Abstract:
Vehicular cloud computing is a technological paradigm shifting which takes advantage of cloud computingto provide vehicles with useful computing resources and services. With the rapid advancementof intelligent vehicles and Intelligent Transportation System infrastructures, some researches on theliteratures have put forth a vision of the combination of vehicular network with could computing inrecent. However, little efforts have concentrated on security features for vehicular cloud services. Inparticular, privacy is one of the critical security issues in vehicular cloud as well as vehicular communicationssince a third-party entity may be involved in cloud service management and operations. Inthis paper, we design a privacy preserving vehicle-to-infrastructure cloud access management systemin which neither global eavesdropper nor any single system management entity can trace a vehiclefor service provision. We make use of pre-loaded pseudonyms to generate anonymous service accesstokens for vehicles and RSU local revocation check to reduce the size of revocation list in the system.

Abstract:
<p>Vehicular Cloud Networks (VCN) is the network that ensures mobility and availability of resources allowing new services and applications like Network as a Service (NaaS), STorage as a Service (STaaS), Computation as a Service (CompaaS) and Cooperation as a Service (CaaS). In this paper, we propose a solution to secure the Vehicular Cloud Network (VCN). Our challenge in this work is to adapt the PKI architecture, which is mainly used in wired networks to be used in VCN. To propose a security solution for Vehicular Cloud Networks (VCN), our work is based on three steps; the first one is to make network architecture study, where we tried to highlight the main network components. The second step is to propose the security solution architecture. Finally, the last step is to program a test and validate the solution using a simulation.</p>

Abstract:
Heterogeneous vehicular communication on the Internet of connected vehicle (IoV) environment is an emerging research theme toward achieving smart transportation. It is an evolution of the existing vehicular ad hoc network architecture due to the increasingly heterogeneous nature of the various existing networks in road traffic environments that need to be integrated. The existing literature on vehicular communication is lacking in the area of network optimization for heterogeneous network environments. In this context, this paper proposes a heterogeneous network model for IoV and service-oriented network optimization. The network model focuses on three key networking entities: vehicular cloud, heterogeneous communication, and smart use cases as clients. Most traffic-related data–oriented computations are performed at cloud servers for making intelligent decisions. The connection component enables handoff-centric network communication in heterogeneous vehicular environments. The use-case-oriented smart traffic services are implemented as clients for the network model. The model is tested for various service-oriented metrics in heterogeneous vehicular communication environments with the aim of affirming several service benefits. Future challenges and issues in heterogeneous IoV environments are also highlighted.

Abstract:
In recent years, cloud computing has gained more and more popularity. The motivation towards implementing cloud computing in vehicular networks is due to the availability of communication, storage, and computing resources represented by communication, vehicles, roadside units (RSUs), and central servers. These resources can be utilized and provided to vehicles, drivers on the road, travellers, and customers on the internet. Intelligent Transportation System (ITS) applications can utilize vehicular cloud computing to provide efficient real-time services, as well as to improve transportation safety, mobility, and comfort levels for drivers. In this paper, all possible vehicular cloud models are presented. Each vehicular cloud model offers different services. Integrating all vehicular cloud models into one integrated system will provide all services and serve internet users, passengers, and vehicles. Therefore, a generic vehicular cloud model is proposed. After that, a new service called Virtual Vehicle is proposed in vehicular cloud computing. The virtual vehicle is a virtual machine that migrates from one physical vehicle to another. It provides the same services as the physical vehicle according to the consumer's requirements.

Abstract:
In vehicular edge computing, vehicles move along the road and request the services from the nearest edge servers with low latency. Due to the limitation of computation capacity of vehicular devices, the services should be offloaded on RSUs equipped with edge servers to provide service with low latency. Noticed that the location of service offloading may affect the service requesting delay directly, and it may exist some interrelationship between interacting services; all of these are rarely considered in recent studies. To address such problems, we propose a collaborative service offloading approach with deep reinforcement learning in vehicular edge computing named CSO-DRL. Our approach first divides the road segments by k-means-based algorithm through analyzing the trajectory data of vehicles, and then the offloading location is determined by observing the vehicle running status. Secondly, the interacting services are discovered by a parallel frequent pattern-based algorithm efficiently. Furthermore, the collaborative service offloading algorithm is presented by the DDPG model for offloading the interacting services, which can minimize the service requesting delay and data communication delay between interacting services. Finally, the efficiency of the algorithm is evaluated by real-world data-based simulation experimental evaluations. The results show our algorithm can obtain a lower delay than other baseline algorithms in searching for the optimal service offloading strategy.

Abstract:
Internet of Vehicles (IoV) enables numerous in-vehicle applications for smart cities, driving increasing service demands for processing various contents (e.g., videos). Generally, for efficient service delivery, the contents from the service providers are processed on the edge servers (ESs), as edge computing offers vehicular applications low-latency services. However, due to the reusability of the same contents required by different distributed vehicular users, processing the copies of the same contents repeatedly in an edge server leads to a waste of resources (e.g., storage, computation, and bandwidth) in ESs. Therefore, it is a challenge to provide high-quality services while guaranteeing the resource efficiency with edge content caching. To address the challenge, an edge content caching method for smart cities with service requirement prediction, named E-Cache, is proposed. First, the future service requirements from the vehicles are predicted based on the deep spatiotemporal residual network (ST-ResNet). Then, preliminary content caching schemes are elaborated based on the predicted service requirements, which are further adjusted by a many-objective optimization aiming at minimizing the execution time and the energy consumption of the vehicular services. Eventually, experimental evaluations prove the efficiency and effectiveness of E-Cache with spatiotemporal traffic trajectory big data.

Abstract:
Vehicular Ad hoc NETwork is a promising technology providing important facilities for modern transportation systems. It has garnered much interest from researchers studying the mitigation of attacks including distributed denial of service attacks. Machine learning techniques, which mainly rely on the quality of the datasets used, play a role in detecting many attacks with a high level of accuracy. We conducted a comprehensive literature review and found many limitations on the datasets available for distributed denial of service attacks on Vehicular Ad hoc NETwork including the following: unavailability of online versions, an absence of distributed denial of service traffic, unrepresentative of Vehicular Ad hoc NETwork, and no information regarding the network configurations. Therefore, in this article, we proposed a novel simulation technique to generate a valid dataset called Vehicular Ad hoc NETwork distributed denial of service dataset, which is dedicated to Vehicular Ad hoc NETworks. Vehicular Ad hoc NETwork distributed denial of service dataset holds information on distributed denial of service attack traffic considering Vehicular Ad hoc NETwork architecture, traffic density, attack intensity, and nodes mobility. Well-known simulation tools such as SUMO, OMNeT++, Veins, and INET were used to ensure that all the properties of Vehicular Ad hoc NETwork have been captured. We then compared Vehicular Ad hoc NETwork distributed denial of service dataset with several studies to prove its novelty and evaluated the dataset using several machine learning models. We confirmed that studied models using this dataset achieved high accuracy above 99.5% except support-vector machine that achieved 97.3%.

Abstract:
A new networking paradigm, Vehicular Edge Computing (VEC), has been introduced in recent years to the vehicular network to augment its computing capacity. The ultimate challenge to fulfill the requirements of both communication and computation is increasingly prominent, with the advent of ever-growing modern vehicular applications. With the breakthrough of VEC, service providers directly host services in close proximity to smart vehicles for reducing latency and improving quality of service (QoS). This paper illustrates the VEC architecture, coupled with the concept of the smart vehicle, its services, communication, and applications. Moreover, we categorized all the technical issues in the VEC architecture and reviewed all the relevant and latest solutions. We also shed some light and pinpoint future research challenges. This article not only enables naive readers to get a better understanding of this latest research field but also gives new directions in the field of VEC to the other researchers.

Abstract:
Dans cette thèse nous nous sommes intéressés à sécuriser les réseaux véhiculaires ad hoc (VANETs) contre les attaques de déni de service (DoS) jugées comme étant les plus dangereuses pour ces réseaux. Notre travail peut être subdivisé en trois grandes parties.Dans un premier temps, nous avons étudié les différentes vulnérabilités auxquelles sont exposés les VANETs, spécialement les attaques DoS. Vu notre expertise en matière de la cryptographie, nous avons exploré, dégagé et classifié des solutions possibles à une grande panoplie de brèches de sécurité VANETs. En effet, nous avons montré que la cryptographie permet de résoudre divers problèmes de sécurité VANETs. Notre première contribution dans ce sens est un algorithme de génération de clés de groupe pour les convois de véhicules. Dans notre deuxième contribution nous avons conçu deux nouvelles méthodes de détection d’attaques DoS. Dans ce contexte, notre premier algorithme de détection est basé sur la régression linéaire, la logique floue ainsi que la définition de trois nouvelles métriques spécifiques VANETs. Dans notre deuxième algorithme de détection nous avons défini une nouvelle métrique à base de l'entropie de Shannon que nous avons introduite pour la première fois pour détecter tel type d’attaques. Notre troisième contribution a été consacrée à la réaction contre les attaques une fois détectées. Pour cela, nous avons eu recourt à l'utilisation des techniques offertes par la théorie des jeux. Nous avons proposé deux jeux non-coopératifs de réaction sous forme stratégique et extensive. Pour chacune des phases de détection et de réaction, les expérimentations ont été faites essentiellement pour les attaques greedy et jamming. Nos algorithmes proposés présentent l'avantage de la rapidité, d'être exécutés par n'importe quel nœud du réseau et ne nécessitent aucune modification du protocole IEEE 802.11p utilisée comme standard de la couche MAC et PHY des réseaux véhiculaires.Au cours de ce travail, nous avons pu participer à la sécurisation des réseaux VANETs. Cependant nous jugeons qu'il reste beaucoup à faire. A savoir par exemple, l'étude des solutions cryptographiques que nous avons menée nous a permis de découvrir à quel point l'usage de la cryptographie pour la sécurité des VANETs est un sujet assez vaste et qui nécessite d'être encore mieux exploré. Ceci constituera pour nous une ouverture assez prometteuse
In this thesis we interested in securing Vehicular Ad hoc Networks (VANETs) against Denial of Service attacks (DoS) judged to be the most dangerous attacks to such networks. Our work can be divided into three main parts. First, we studied all the various possible existing vulnerabilities to which are exposed VANETs, we focused especially on denial of service attacks. Based on our expertise in cryptography, we explored, identified and classified the possible solutions to a wide range of VANET security breaches from a cryptographic point of view. Indeed, we showed that cryptography with its primitives and fairly powerful tools solves many VANET security problems. Our first contribution in this direction is a secure group key generation algorithm for VANET platoons. In our second contribution, we have developed two new techniques to detect denial of service attacks in VANET networks mainly characterized by the high mobility and frequent disconnections which considerably complicate the detection. Our first detection algorithm is based on the linear regression mathematical concept, fuzzy logic and three newly defined VANET appropriate metrics. In our second algorithm we define a new Shannon Entropy based metric that we introduced for the first time to detect DoS attacks in VANET. Our third contribution was devoted to the reaction against the detected attacks. For that, we used the techniques offered by game theory. We have proposed two non-cooperative reaction games in strategic and extensive forms. For both detection and reaction proposed schemes, experiments were made essentially for the greedy behavior and jamming attacks. All our proposed algorithms present the advantage of rapidity, to be executed by any node of the network and do not require any modification of the 802.11p MAC layer protocol used as a standard for VANETs. In this work, we have participated in securing VANETs, however we believe that much remains to be done. Namely, for example the study of cryptographic solutions we have conducted, allowed us to discover how the use of cryptography for VANET security is a fairly broad topic which needs to be better explored. This will be for us a very promising subject

Abstract:
With Vehicular mobile communication becoming a daily requirement and an ever increasing number of services being available to passengers, it is clear that vehicular networks efficient communication systems. VANETs, one of the most significant trends in ad-hoc networking, has much to gain from improved content delivery and one of the leading contenders for mobile networks is the Information-Centric networking approach. Its peculiarities define the Vehicular Environment requires specialized solutions, tailored for highly mobile environments. The main contribution of this thesis is the introduction of a novel architecture and components. We perform extensively discuss Information-Centric Vehicular Ad-hoc Networks. Additionally, we perform an in-depth analysis of bus-based transit systems into VANETs not only as participating members but as service providers and official agents including roles and potential challenges. We perform statistical analysis and analyze world data to denote the intrinsic potential of public transit systems. From the discussions presented, we introduce a novel service-based system architecture for Information-Centric Networking named SEVeN. The proposed model is designed to enable service exchange and service management in highly competitive vehicular ad-hoc networks. The proposed SEVeN architecture includes the introduction of a novel purpose-defined naming policy and service sub-layer as well as a service prioritization policy named LBD. We also discuss the current state of ICN caching in VANET, existing issues faced by vehicular networks and potential approaches based on intermediate cache coordination that can be taken to mitigate existing shortcommings. We perform a series of simulations and analyze the efficiency of popular caching in various network configurations to denote current shortcomings. From this discussion, we propose a cache content insertion policies, UG-Cache and MG-Cache, for ICN-VANETs. In these cache policies, cache insertion decisions are made based on recommendations from content sender dependent on request frequency and cache distance. We also introduce a caching policy based on collaborative observation of locality in request frequency, designed to allow vehicles to preemptively distribute and store in a reserved portion of the cache based on the cooperative observation of requests with provider-based location correlation. All novel elements proposed by this thesis are discussed, described, evaluated within the chapters of this thesis.

Abstract:
Le contrôle de congestion des canaux sans fil pour la communication véhiculaires (V2X) basée sur IEEE 802.11p ont été conçus pour un seul service de sécurité routière notamment ‘Cooperative Awareness’. Les futurs véhicules connectés seront basés sur plusieurs services V2X, avec un besoin de communication hétérogène, auxquels les mécanismes existants ne répondent pas. Dans cette thèse, on analyse plusieurs protocoles de contrôle de congestion et d’allocation de ressources de canaux, normalisés en Europe pour le déploiement V2X initial. Nous présentons des problèmes liés à l’approche existante, notamment l’utilisation inefficace de la capacité des canaux, la coordination dans la pile protocolaire, la gestion des ressources parmi plusieurs services et l’allocation des ressources pour un besoin asymétrique par les véhicules. On propose des améliorations en tenant compte des exigences des futurs scénarios V2X. Nous montrons les limites de la classification statique des services V2X pour la qualité de service et proposons une classification dynamique. Nous concevons un orchestrateur de ressources afin d'améliorer la coordination dans la pile protocolaire et de répartir dynamiquement la ressource de canal parmi plusieurs services d'un véhicule. En outre, on présente un mécanisme permettant d'orchestrer de manière décentralisée les ressources de canal parmi une distribution mixte de véhicules ayant des exigences d'utilisation de canal diverse, dans un canal de communication congestionné. Les résultats analytiques et résultats par simulations montrent la validité de notre approche qui améliore la performance des applications V2X, par rapport aux protocoles standardisés existants
Wireless channel congestion control and decentralized resource allocation for 802.11p based V2X communication have been widely investigated for a single Cooperative Awareness service, considering mostly homogenous communication requirement per vehicle. Future connected vehicles will be based on multiple V2X services, with heterogenous number of services and communication needs, which existing resource allocation mechanisms does not address. In this thesis, we analyze several decentralized congestion control and channel resource allocation protocols standardized in Europe for initial V2X deployment. We present issues with the existing approach, in particular the inefficient channel capacity utilization, problematic cross layer coordination, inability to balance resources among multiple V2X safety services and distributed resource allocation for asymmetric number of services per vehicle. We propose improvements to the shortcomings, considering the requirements of future V2X scenarios. We demonstrate the limitations of classifying V2X services using static priority for Quality of Service and propose dynamic prioritization. We design a resource orchestrator at the Service Layer to improve cross layer coordination and dynamically distribute the limited channel resource among multiple services of a vehicle. Furthermore, we present a mechanism to decentrally orchestrate channel resource among a mixed distribution of vehicles with diverse channel usage requirements under channel congestion. Analytical and simulation-based results show the validity of our proposed approach, and the V2X application performance improvement it renders, compared to existing standardized protocols

Abstract:
Les accidents de la circulation sont un des plus grands problèmes de sureté publique. Par conséquent la sécurité routière a toujours été la principale préoccupation des acteurs de la sécurité des transports. Durant les dernières décennies, les pouvoirs publics et les entreprises du secteur automobile ont été impliqués dans l'amélioration de nos systèmes de transport de la sécurité en réduisant les conséquences des accidents imminents et en diminuant le nombre d'accidents de la route. Néanmoins, la plupart de ces mesures préventives ne peut assurer la sécurité passive , car ils se concentrent sur la phase de collision. En fait, les matériaux comme les airbags réduisent l'impact d'un accident, mais ne l'empêchent pas. Cette reconnaissance de l'insuffisance de ces mesures passives a orienté à des perspectives industrielles nouvelles et innovantes qui cherchent à éviter les accidents et de détecter les dangers à l'avance au lieu de minimiser les dommages. En fait, selon des études pertinentes, 60 pers des accidents peuvent être évités si le conducteur avait été alerté d'une demi-seconde avant la collision. Des mesures drastiques sont déjà prises par les constructeurs automobiles afin d'offrir aux conducteurs une télématique plus large et donc d'améliorer leur gamme de sensibilisation. Si une collision est inévitable, la technologie de sécurité active peut préparer de manière proactive le véhicule pour l'impact à réduire les dommages. Par exemple, les capteurs de véhicules sont utilisés pour mesurer et évaluer l'état et de l'environnement d'un véhicule, permettant l'émission d'alertes précoces aux conducteurs. [...]
Road traffic crashes are one of the world's largest public health and injury problems. Therefore road security has always been the main concern of transportation security stakeholders. During the last decades, public authorities and automotive companies have been involved in the safety improvement of our transportation systems by reducing the consequences of imminent accidents and decreasing the number of road injuries. Nevertheless, most of these preventive measures can only provide passive safety since they focus on the post collision phase. In fact, materials of energy absorption like airbags reduce the impact of an accident but do not prevent it. This recognition of the inadequacy of these passive measures has oriented industrials to new and innovative perspectives that seek to avoid accidents and detect dangers in advance rather than minimize the damage. In fact, according to relevant studies, 60pers of accidents can be avoided if the driver had been alerted half a second before the collision. Drastic steps are already taken by automobile manufacturers to offer to drivers a larger telematics horizon and therefore enhance their range of awareness. If a collision is inevitable, active safety technology can proactively prepare the vehicle for the impact to reduce injuries. For example, vehicles' sensors are employed to measure and assess a vehicle' s condition and environment, enabling the issuance of early warnings to drivers. On the other hand, a remarkable and similar step in that direction is achieved by networking research community using vehicular networks within Intelligent Transportation Systems (ITS)

Abstract:
Intelligent Transportation Systems (ITS) are gaining momentum among researchers. ITS encompasses several technologies, including wireless communications, sensor networks, data and voice communication, real-time driving assistant systems, etc. These states of the art technologies are expected to pave the way for a plethora of vehicular network applications. In fact, recently we have witnessed a growing interest in Vehicular Networks from both the research community and industry. Several potential applications of Vehicular Networks are envisioned such as road safety and security, traffic monitoring and driving comfort, just to mention a few. It is critical that the existence of convenience or driving comfort services do not negatively affect the performance of safety services. In essence, the dissemination of safety services or the discovery of convenience applications requires the communication among service providers and service requesters through constrained bandwidth resources. Therefore, service discovery techniques for vehicular networks must efficiently use the available common resources. In this thesis, we focus on the design of bandwidth-efficient and scalable service discovery protocols for Vehicular Networks. Three types of service discovery architectures are introduced: infrastructure-less, infrastructure-based, and hybrid architectures. Our proposed algorithms are network layer based where service discovery messages are integrated into the routing messages for a lightweight discovery. Moreover, our protocols use the channel diversity for efficient service discovery. We describe our algorithms and discuss their implementation. Finally, we present the main results of the extensive set of simulation experiments that have been used in order to evaluate their performance.

Abstract:
Les réseaux ad hoc de véhicules accueillent une multitude d’applications intéressantes. Parmi celles-ci, les applications d’info-divertissement visent à améliorer l’expérience des passagers. Ces applications ont des exigences rigides en termes de délai de livraison et de débit. De nombreuses approches ont été proposées pour assurer la qualité du service des dites applications. Elles sont réparties en deux couches : réseau et contrôle d’accès. Toutefois, ces méthodes présentent plusieurs lacunes. Cette thèse a trois volets. Le premier aborde la question du routage dans le milieu urbain. A cet égard, un nouveau protocole, appelé SCRP, a été proposé. Il exploite l’information sur la circulation des véhicules en temps réel pour créer des épines dorsales sur les routes et les connecter aux intersections à l’aide des nœuds de pont. Ces derniers collectent des informations concernant la connectivité et le délai, utilisées pour choisir les chemins de routage ayant un délai de bout-en-bout faible. Le deuxième s’attaque au problème d’affectation des canaux de services afin d’augmenter le débit. A cet effet, un nouveau mécanisme, appelé ASSCH, a été conçu. ASSCH collecte des informations sur les canaux en temps réel et les donne à un modèle stochastique afin de prédire leurs états dans l’avenir. Les canaux les moins encombrés sont sélectionnés pour être utilisés. Le dernier volet vise à proposer un modèle analytique pour examiner la performance du mécanisme EDCA de la norme IEEE 802.11p. Ce modèle tient en compte plusieurs facteurs, dont l’opportunité de transmission, non exploitée dans IEEE 802.11p.
The fact that vehicular ad hoc network accommodates two types of communications, Vehicle-to-Vehicle and Vehicle-to-Infrastructure, has opened the door for a plethora of interesting applications to thrive. Some of these applications, known as infotainment applications, focus on enhancing the passengers' experience. They have rigid requirements in terms of delivery delay and throughput. Numerous approaches have been proposed, at medium access control and routing layers, to enhance the quality of service of such applications. However, existing schemes have several shortcomings. Subsequently, the design of new and efficient approaches is vital for the proper functioning of infotainment applications. This work proposes three schemes. The first is a novel routing protocol, labeled SCRP. It leverages real-time vehicular traffic information to create backbones over road segments and connect them at intersections using bridge nodes. These nodes are responsible for collecting connectivity and delay information, which are used to select routing paths with low end-to-end delay. The second is an altruistic service channel selection scheme, labeled ASSCH. It first collects real-time service channels information and feeds it to a stochastic model that predicts the state of these channels in the near future. The least congested channels are then selected to be used. The third is an analytical model for the performance of the IEEE 802.11p Enhanced Distributed Channel Access mechanism that considers various factors, including the transmission opportunity (TXOP), unexploited by IEEE 802.11p.

Abstract:
Today, the increasing number of applications based on the Internet of Things, as well as advances in wireless communication, information and communication technology, and mobile cloud computing have allowed users to access a wide range of resources while mobile. Vehicular clouds are considered key elements for today’s intelligent transportation systems. They are outfitted with equipment to enable applications and services for vehicle drivers, surrounding vehicles, pedestrians and third parties. As vehicular cloud computing has become more popular, due to its ability to improve driver and vehicle safety and provide provisioning services and applications, researchers and industry have growing interest in the design and development of vehicular networks for emerging applications. Though vehicle drivers can now access a variety of on-demand resources en route via vehicular network service providers, the development of vehicular cloud provisioning services has many challenges. In this dissertation, we examine the most critical provisioning service challenges drivers face, including, cost, privacy and latency. To this point, very little research has addressed these issues from the driver perspective. Privacy and service latency are certainly emerging challenges for drivers, as are service costs since this is a relatively new financial concept. Motivated by the Quality of Experience paradigm and the concept of the Trusted Third Party, we identify and investigate these challenges and examine the limitations and requirements of a vehicular environment. We found no research that addressed these challenges simultaneously, or investigated their effect on one another. We have developed a Quality of Experience framework that provides scalability and reduces congestion overhead for users. Furthermore, we propose two theory-based frameworks to manage on-demand service provision in vehicular clouds: Auction-driven Multi-objective Provisioning and a Multiagent/Multiobjective Interaction Game System. We present different approaches to these, and show through analytical and simulation results that our potential schemes help drivers minimize costs and latency, and maximize privacy.

Abstract:
The Virginia Tech Center for Wireless Telecommunicationsâ (CWT) Public Safety Cognitive Radio (PSCR) addresses the radio interoperability issues that plague many of the existing public safety radios â disparate frequency bands, incompatible modulation schemes and lack of active channel detection features. The PSCR allows the operator to scan for active channels, classify the detected channels, connect to any of the recognized waveforms and begin analog audio communication as well as bridge two incompatible waveforms together. The PSCR, although very useful, unfortunately is not portable enough to be used by public safety officials. The power requirement, processing requirement and equipment is respectively large, hungry and bulky. In this thesis, a possible solution to the portability problem is addressed by installing the PSCR in a public safety vehicle and using a Personal Digital Assistant (PDA) for remote access. The PDA allows the user to remotely scan, classify, talk, and bridge waveforms similar in operation to the PSCR. An ergonomically designed interface masks the channel and modulation selection procedure. This architecture can be extended to offer service to any remotely connected device. In the second part of this thesis, the concept of remote access is extended to a wide-area wireless public safety network. A public safety network consisting of heterogeneous devices is proposed utilizing a small number of backbone nodes. The major research focus of this section is the algorithm for distributing services across the network. Service discovery is optimized to reduce the overhead of service messages and multiple service distribution techniques are utilized depending on the location of the services. Simulation is performed to evaluate the performance of the service discovery protocol in terms of overhead, dissemination time and scalability. The proposed protocol is determined to be superior to the competition in the overhead and scalability tests.

Abstract:
Vehicle to Everything (V2X), y compris véhicule à véhicule (V2V) et véhicule à infrastructure (V2I), est la base de communications véhiculaires, où Les messages de sécurité routière active, d’infotainment et de gestion du trafic sont transmis sur des liaisons à bande passante élevée, à faible temps de latence et à haute fiabilité, ouvrant ainsi la voie à une conduite totalement autonome. L’objectif ultime des systèmes de communication V2X de la prochaine génération est de permettre une conduite coopérative sans accident. Pour atteindre cet objectif, le système de communication devra permettre un ensemble diversifié de cas d'usage, chacun avec un ensemble spécifique d'exigences. L'analyse des exigences relatives aux principales catégories de cas d’usage, en particulier les applications de temps réel critiques, souligne la nécessité d'une conception de système V2X efficace, capable de fournir les performances du réseau. La technologie de cinquième génération (5G), avec sa Qualité de Service (QoS) fournie en termes de capacité élevée et de faible temps de latence, est préconisée comme solution pour faire face aux exigences strictes imposées par les applications V2X.Dans cet écosystème 5G véhiculaire, diverses technologies de communication sont envisagés, allant des communications IEEE 802.11p, LTE, LTE-V aux Visible Light Communications. Par conséquent, l’hétérogénéité des technologies d’accès radio suscitera des inquiétudes quant à la gestion transparente de la mobilité et à la garantie de qualité de service.Cette thèse propose un nouveau système de gestion de la mobilité conçu pour les réseaux de véhicules 5G, basé sur la technologie émergente SDN (Software Defined Networking). SDN offre une programmabilité réseau qui vise à obtenir une allocation efficace des ressources du réseau et une gestion de la mobilité.Notre travail de recherche vise trois objectifs. Dans un premier temps, nous concevons une architecture de réseau de véhicules. Au sommet de cette architecture, nous implémentons deux Applications SDN, à savoir application de sélection de réseau et gestion de la mobilité Application. L'architecture proposée est renforcée par une solution de placement de contrôleur visant à réduire le temps de latence des communications. De plus, une préoccupation particulière est consacrée à la conception d’une application de sécurité active de la route SDN contrôlant l’emplacement des capteurs de vitesse sur les routes. L’application proposée vise à réduire le taux d’accidents, objectif principal du futur système de transport intelligent.Le deuxième objectif de cette thèse aborde le problème de la gestion de la mobilité.Ceci est réalisé en implémentant des applications liées à la mobilité SDN au sommet de la topologie de réseau adoptée. La première application est dédiée à la résolution du problème de sélection du réseau. Son objectif est de mapper les sessions V2X en cours sur la technologie correspondante. La deuxième application est conçue pour résoudre le handover; ceci est réalisé en utilisant la duplication de paquets et en introduisant un algorithme de routage efficace.Le troisième objectif de la thèse est axé sur l’approvisionnement en qualité de service pour les communications V2X
Vehicle to everything (V2X), including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure(V2I), is the umbrella for the vehicular communication system, where active road safety, infotainment and traffic management messages are transmitted over high-bandwidth, low-latency, high-reliability links, paving the way to fully autonomous driving. The ultimate objective of next generation V2X communication systems is enabling accident-free cooperative driving that uses the available roadway efficiently. To achieve this goal, the communication system will need to enable a diverse set of use cases, each with a specific set of requirements.The main use case categories requirements analysis, specifically the critical realtime applications, points out the need for an efficient V2X system design that could fulfill the network performance. The Fifth Generation (5G) technology, with its provisioned QoS features in terms of high capacity and low latency, is advocated as a prominent solution to cope with the firm requirements imposed by V2X applications.In this multifaceted vehicular 5G ecosystem, diverse communication technologies are envisioned, spanning from IEEE 802.11p, LTE, LTE-V to vehicular visible light communications. Therefore, the heterogeneity of radio access technologies will raise a concern regarding the seamless mobility management and the quality of service guarantee.This thesis provides a novel mobility management scheme devised for 5G vehicular networks based on the emerging Software Defined Networking (SDN) technology.SDN provides network programmability that strives to achieve an efficient network resource allocation and mobility management.Our research work tackles three objectives. At a first stage, we design a software defined vehicular network topology. On the top of this topology, we implement twoSDN applications, namely Network Selection Application and Mobility Management Application. The proposed architecture is enhanced by a controller placement solution that aims at reducing communication latency. Moreover, a special concern is devoted to design a SDN road active safety application that controls speed traps placement. The proposed application aims at reducing accidents rate which is a main purpose of future Intelligent Transportation System.The second objective of this thesis tackles the mobility management problem. This is achieved by implementing SDN mobility related applications on the top of the adopted network topology. The first application is dedicated to solve the network selection problem; it aims at mapping running V2X sessions to the corresponding technology. The second application is conceived to solve the handover procedure; this is achieved using packets duplication and introducing an efficient routing algorithm.The third thesis objective is focused on QoS provisioning for V2X communications

Abstract:
This research explores the benefits of a pedestrian crosswalk that is physically displaced from the intersection, using simulation software to estimate the benefits in terms of delay and pedestrian travel time. In many cases, the displaced pedestrian crossing may provide benefits such as reduced vehicle delay, reduced crossing distance, increased opportunity for signal progression, and reduced conflicts with turning vehicles. The concurrent pedestrian service that is traditionally used presents potential conflicts between pedestrians and three vehicular movements: right turns, permissive left turns, and right turns on red. The findings of this research suggest that a displaced pedestrian crossing should be considered as an option by designers when serving pedestrians crossing multi-lane arterials. In addition to reduced delay, pedestrian safety may be improved due to the shorter crossing distance, the elimination of conflicts with turning vehicles, and the potential for high driver compliance rates associated with signals, such as pedestrian hybrid beacons.

Abstract:
Over the years, public transit agencies have been trying to improve their operations by continuously evaluating best practices to better serve patrons. Washington Metropolitan Area Transit Authority (WMATA) oversees the transit bus operations in the Washington Metropolitan Area (District of Columbia, some parts of Maryland and Virginia). One practice attempted by WMATA to improve bus travel time and transit reliability has been the implementation of designated bus lanes (DBLs). The District Department of Transportation (DDOT) implemented a bus priority program on selected corridors in the District of Columbia leading to the installation of red-painted DBLs on corridors of H Street, NW, and I Street, NW. This study evaluates the impacts on the performance of transit buses along with the general traffic performance at intersections on corridors with DBLs installed in Washington, DC by using a “before” and “after” approach. The team utilized non-intrusive video data to perform vehicular turning movement counts to assess the traffic flow and delays (measures of effectiveness) with a traffic simulation software. Furthermore, the team analyzed the Automatic Vehicle Locator (AVL) data provided by WMATA for buses operating on the study segments to evaluate bus travel time. The statistical analysis showed that the vehicles traveling on H Street and I Street (NW) experienced significantly lower delays during both AM (7:00–9:30 AM) and PM (4:00–6:30 PM) peak hours after the installation of bus lanes. The approximation error metrics (normalized squared errors) for the testing dataset was 0.97, indicating that the model was predicting bus travel times based on unknown data with great accuracy. WMATA can apply this research to other segments with busy bus schedules and multiple routes to evaluate the need for DBLs. Neural network models can also be used to approximate bus travel times on segments by simulating scenarios with DBLs to obtain accurate bus travel times. Such implementation could not only improve WMATA’s bus service and reliability but also alleviate general traffic delays.

Abstract:
The Tahoma Creek Bridge on the southwest side of Mount Rainier is an essential crossing for year-round vehicular access to Mount Rainier National Park (MORA). This site is also exposed to significant hydrologic variability, which the current structure was not designed to withstand. Locally enhanced vertical increases to the riverbed elevation, known as aggradation, threaten the structure?s long-term viability. The purpose of this report is to (1) clarify the details of channel maintenance operations related to the bridge; (2) synthesize the natural and human influences of sediment deposition in the lower watershed; and (3) discuss the potential solutions for sustainable bridge maintenance. Information was collected through prior structural inspection reports, raw hydrologic data stored by the National Park Service, and both published and unpublished reports focused on Tahoma Creek. It was found that the height and width of the Tahoma Creek Bridge are severely underfit for relatively common flooding events on Tahoma Creek. Additionally, dredging and sediment storage practices employed to maintain the bridge are ineffective and even enhance aggradation in nominal flow conditions. Further research in the Tahoma Creek Watershed suggests the river is generally efficient at exporting produced sediments and maintains a relatively stable vertical profile in its lower reaches, where the bridge is located. The singular variation from this stable vertical trend at the bridge site suggests locally enhanced aggradation at the bridge is entirely due to the presence of the bridge itself and the channel modification actions taken to support the structure. All told, neither the overall size of the Tahoma Creek Bridge nor the channel modification actions taken to maintain the crossing, are viable for long-term access into MORA. With no changes to the existing bridge profile, the status-quo for operations to manage the Tahoma Creek Bridge will eventually fail to maintain access.

Abstract:
The direct benefits of transport projects are well known; paving roads reduces vehicular operating costs, mass transport systems reduce commuting times and road maintenance prolongs their operating lifespan. Impact evaluation reveals a range of ways in which transport projects improve lives. The empirical evidence shows that paved roads encourage preventive healthcare and increase employment opportunities, mass transport systems improve air quality and reduce crime, and satisfaction of road maintenance increases when services are provided by local communities.Impact evaluations generate valuable information for both executing agencies and stakeholders. Their results provide rigorous measurements of the effect of a project, who benefits the most and why. As a result, the evidence generated by well-conducted impact evaluations is increasingly used to attract resources to effective investments and to guide institutional choices.

Abstract:
Modern automobiles collect around 25 gigabytes of data per hour and autonomous vehicles are expected to generate more than 100 times that number. In comparison, the Apollo Guidance Computer assisting in the moon launches had only a 32-kilobtye hard disk. Without question, the breadth of in-vehicle data has opened new possibilities and challenges. The potential for accessing this data has led many entrepreneurs to claim that data is more valuable than even the vehicle itself. These intrepid data-miners seek to explore business opportunities in predictive maintenance, pay-as-you-drive features, and infrastructure services. Yet, the use of data comes with inherent challenges: accessibility, ownership, security, and privacy. Unsettled Legal Issues Facing Data in Autonomous, Connected, Electric, and Shared Vehicles examines some of the pressing questions on the minds of both industry and consumers. Who owns the data and how can it be used? What are the regulatory regimes that impact vehicular data use? Is the US close to harmonizing with other nations in the automotive data privacy? And will the risks of hackers lead to the “zombie car apocalypse” or to another avenue for ransomware? This report explores a number of these legal challenges and the unsettled aspects that arise in the world of automotive data
