Abstract:
A hybrid wireless network handles both ad hoc networks and infrastructure networks, these networks are affected by malicious attacks which affect the routing by packet drops, modifications and selective forwarding. These attacks lead to the link failure in a network. Link failures are the main reason for packet loss and network unreliability in these kinds of networks. Due to link failures, the life time of the network and the performance of routing path is affected. The previous security mechanisms for protecting wireless networks are not sufficient for hybrid networks. In this article, the authors propose a trust-based security model to enhance security factors in hybrid networks. The proposed routing protocols implemented in hybrid network platforms consist of different networks such as a fixed node for WLANs (wireless televisions, personal computers, printers, cellular, etc.) with zero mobility, a sensor node for WSNs with zero mobility, mobile nodes with movements considered MANETs, and nodes with high movements (vehicles) considered as VANETs. This article proposes routing protocols to avoid link failure in the current routing path and provide quick recovery, improve the throughput, reduce end to end delay, maximize the life time of routing path without affecting energy consumption and QoS/QoE while compared with other existing techniques.

Abstract:
A heterogeneous vehicular network (HetVNET) is a promising network architecture that combines multiple network technologies such as IEEE 802.11p, dedicated short-range communication (DSRC), and third/fourth generation cellular networks (3G/4G). In this network area, vehicle users can use wireless fidelity access points (Wi-Fi APs) to offload 4G long-term evolution (4G-LTE) networks. However, when using Wi-Fi APs, the vehicles must organize themselves and select an appropriate mobile gateway (MGW) to communicate to the cellular infrastructure. Researchers are facing the problem of selecting the best MGW vehicle to aggregate vehicle traffic and reduce LTE load in HetVNETs when the Wi-Fi APs are unavailable for offloading. The selection process utilizes extra network overhead and complexity due to the frequent formation of clusters in this highly dynamic environment. In this study, we proposed a non-cluster adaptive QoS-aware gateway selection (AQAGS) scheme that autonomously picks a limited number of vehicles to act as LTE gateways based on the LTE network’s load status and vehicular ad hoc network (VANET) application’s QoS requirements. The present AQAGS scheme focuses on highway scenarios. The proposed scheme was evaluated using simulation of Urban mobility (SUMO) and network simulator version 2 (NS2) simulators and benchmarked with the clustered and non-clustered schemes. A comparison was made based on the end-to-end delay, throughput, control packet overhead (CPO), and packet delivery ratio (PDR) performance metrics over Voice over Internet Protocol (VoIP) and File Transfer Protocol (FTP) applications. Using VoIP, the AQAGS scheme achieved a 26.7% higher PDR compared with the other schemes.

Abstract:
Mobility management is an essential challenge for supporting reliable multimedia data streaming over wireless and mobile networks in the Internet of Things (IoT) for location-based mobile marketing applications. The communications among mobile nodes for IoT need to have a seamless handover for delivering high quality multimedia services. The Internet Engineering Task Force (IETF) mobility management schemes are the proposals for handling the routing of IPv6 packets to mobile nodes that have moved away from their home network. However, the standard mobility management scheme cannot prevent packet losses due to longer handover latency. In this article, a new enhanced data streaming route optimization scheme is introduced that uses an optimized Transmission Control Protocol (TCP) realignment algorithm in order to prevent the packet disordering problem whenever the nodes in the IoT environment are communicating with each other. With the proposed scheme, data packets sequence realignment can be prevented, the packet traffic speed can be controlled, and the TCP performance can be improved. The experimental results show that managing the packet order in proposed new scheme remarkably increases the overall TCP performance over mobile networks within the IoT environment thus ensuring the high quality of service (QoS) for multimedia data streaming in location-based mobile marketing applications.

Abstract:
The number of wireless services and devices have remarkably increased, especially since the introduction of smart phones. The population of mobile nodes (MNs) is now exceeding the traditional non-mobile nodes. Mobility is a key factor in mobile core networks as it is responsible for providing continuous communication when a MN is on the move. Currently, a centralized mobile core network architecture is implemented, which has certain limitations. Distributed mobility management (DMM) is often seen as a solution to the problems associated with centralized mobility management (CMM). Address and tunneling management are big challenges for current DMM-based mobility protocols. Keeping in mind the current advancement of mobile network architecture, this paper proposes a novel tunnel-free distributed mobility management support protocol intended for such an evolution. In addition, the performance of the existing DMM IPv6 mobility management protocols in the context of handover latency, handover blocking probability, and data packet loss is analyzed and compared to the proposed framework. The performance analyses show that the proposed tunnel-free method can reduce about 12% of handover latency, 71% of handover blocking probability, and 82% of data packet loss.

Abstract:
<p>The IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) was proposed for various applications of IPv6 low power wireless networks. While RPL supports various routing metrics and is designed to be suitable for wireless sensor network environments, it does not consider the mobility of nodes. Therefore, there is a need for a method that is energy efficient and that provides stable and reliable data transmission by considering the mobility of nodes in RPL networks. In this paper a new heuristic flabellum algorithm inspired by physical and biological behaviour of flabella in the sea is presented, and bottleneck and swarm problems are resolved through managing the moving nodes by flabellum algorithm. Finally, the proposed algorithm’s performance is evaluated using the Cooja simulator. The proposed algorithm;Flabellum RPL; shows significant improvements with regards to packet delivery, and convergence and lifetime.</p>

Abstract:
Wireless networks incorporate Mobile Nodes (MNs) that use wireless access networks to communicate. However, the communication among these MNs are not remained stable due to the poor network coverage during inter mobility. Moreover, the wireless nodes are typically small that results in resource-constrained. Thus, it is uphill to use algorithms having giant processing power or memory footprint. Accordingly, it is essential to check schemes consistently to evaluate the performance within the probable application scenario. To do so, numerical analysis could be a notable method to grasp the performance of mobility management schemes as well as the constraint of evolving mobility management solutions specifically for multi-interfaced MR in Proxy NEMO environment. This paper analyzes handoff performance by using a mathematical model of Multihoming-based scheme to support Mobility management in Proxy NEMO (MM-PNEMO) environment. Moreover, a comparative study has been made among the standard Network Mobility Basic Support Protocol (NEMO BSP), Proxy NEMO (PNEMO) and MM-PNEMO scheme respectively. The performance metrics estimated for these schemes are mainly handoff delay and packet loss. This paper also analysed the packet loss ratio and handoff gain as a function of cell radius, number of SMR and velocity respectively. It is apparent that, the MM-PNEMO scheme shows lower packet loss ratio (1%) compared to NEMO-BSP (11%) and P-NEMO (6%).

Abstract:
Mobility models, synthetic or trace, try to accurately model the movement of a single user or a group of users. Models can be used in simulators and emulators to investigate the consequences of mobility on new protocols or network management techniques. A limitation with current trace mobility models is they are based on empirical data which are limited to specific network types and environments. Limitations with synthetic models are that they are complex, computationally heavy, and lack realism. To address these issue a new approach needs to be taken. One such approach is the use of fluid mechanics and transport theory to represent user mobility. A model based on viscous free irrotational fluid mechanics with empirical data from pedestrian and vehicular studies provide a means of creating realistic group movement characteristics with smooth non random trajectories and smooth continuous velocity. The model is used in an example to provide boundary crossing rates for users in a cellular network and optimising the size of cellular location areas.

Abstract:
Information Centric Networks (ICNs) have been considered one of the most promising candidates to overcome the disadvantages of host-centric architectures when applied to IoT networks, having the potential to address the challenges of a smart city. One of the foundations of a smart city is its sensory capacity, which is obtained through devices associated with the IoT concept. The more sensors spread out, the greater the ability to sense the city. However, such a scale demands high energy requirements and an effective improvement in the energy management is unavoidable. To improve the energy management, we are proposing an efficient forwarding scheme in energy-constrained wireless ICNs. To achieve this goal, we consider the type of devices, their internal energy and the network context, among other parameters. The proposed forwarding strategy extends and adapts concepts of ICNs, by means of packet domain analysis, neighbourhood evaluation and node sleeping and waking strategies. The proposed solution takes advantage of the neighbourhood to be aware of the moments to listen and forward packets in order to consistently address mobility, improving the quality of content delivery. The evaluation is performed by simulation with real datasets of urban mobility, one from the lagoon of “Ria de Aveiro” and the other from a vehicular network in the city of Porto. The results show that the proposed forwarding scheme resulted in significant improvements in network content availability, in the overall energy saving and, consequently, in the network lifetime.

Abstract:
In heterogeneous wireless networks, service providers typically employ multiple radio access technologies to satisfy the requirements of quality of service (QoS) and improve the system performance. However, many challenges remain when using modern cellular mobile communications radio access technologies (e.g., wireless local area network, long-term evolution, and fifth generation), such as inefficient allocation and management of wireless network resources in heterogeneous wireless networks (HWNs). This problem is caused by the sharing of available resources by several users, random distribution of wireless channels, scarcity of wireless spectral resources, and dynamic behavior of generated traffic. Previously, resource allocation schemes have been proposed for HWNs. However, these schemes focus on resource allocation and management, whereas traffic class is not considered. Hence, these existing schemes significantly increase the end-to-end delay and packet loss, resulting in poor user QoS and network throughput in HWNs. Therefore, this study attempts to solve the identified problem by designing an enhanced resource allocation (ERA) algorithm to address the inefficient allocation of available resources vs. QoS challenges. Computer simulation was performed to evaluate the performance of the proposed ERA algorithm by comparing it with a joint power bandwidth allocation algorithm and a dynamic bandwidth allocation algorithm. On average, the proposed ERA algorithm demonstrates a 98.2% bandwidth allocation, 0.75 s end-to-end delay, 1.1% packet loss, and 98.9% improved throughput performance at a time interval of 100 s.

Abstract:
La qualité de communication dans un réseau sans fil est déterminée par la qualité du signal, et plus précisément par le rapport signal à interférence et bruit. Cela pousse chaque récepteur à se connecter à l'émetteur qui lui donne la meilleure qualité du signal. Nous utilisons la géométrie stochastique et la théorie des extrêmes pour obtenir la distribution de la meilleure qualité du signal, ainsi que celles de interférence et du maximum des puissances reçues. Nous mettons en évidence comment la singularité de la fonction d'affaiblissement modifie leurs comportements. Nous nous intéressons ensuite au comportement temporel des signaux radios en étudiant le franchissement de seuils par un processus stationnaire X (t). Nous démontrons que l'intervalle de temps que X (t) passe au-dessus d'un seuil γ → −∞ suit une distribution exponentielle, et obtenons 'egalement des r'esultats caract'erisant des franchissements par X (t) de plusieurs seuils adjacents. Ces r'esultats sont ensuite appliqu'es 'a la gestion de mobilit'e dans les r'eseaux cellulaires. Notre travail se concentre sur la fonction de 'handover measurement'. Nous identifions la meilleure cellule voisine lors d'un handover. Cette fonction joue un rôle central sur expérience perçue par l'utilisateur. Mais elle demande une coopération entre divers mécanismes de contrôle et reste une question difficile. Nous traitons ce problème en proposant des approches analytiques pour les réseaux émergents de types macro et pico cellulaires, ainsi qu'une approche d'auto- optimisation pour les listes de voisinage utilisées dans les réseaux cellulaires actuels.

Abstract:
Group communication, security and 5G technology present a unique dimension of challenges and security remains crucial in the successful deployment of 5G technology across different industry. Group key management plays a vital role in secure group communication. This research work studies various group key management schemes for mobile wireless technology and then a new scheme is proposed and evaluated. The main architecture is analysed, while the components and their roles are established, trust and keying relationships are evaluated, as well as detailed functional requirements. A detailed description of the main protocols required within the scheme is also described. A numerical and simulation analysis is employed to assess the proposed scheme with regards to fulfilling the security requirement and performance requirements. The impact of group size variation, the impact of mobility rate variation are studied with regards to the average rekeying messages induced by each event and 1-affects-n phenomenon. The results obtained from the simulation experiments show that the proposed scheme outperformed other solutions with a minimal number of rekeying messages sent and less number of affected members on each event. The security requirements demonstrate that backward and forward secrecy is preserved and maintained during mobility between areas. Finally, the research work also proposes a 5G-enabled software-defined multicast network (5G-SDMNs), where software-defined networking (SDN) is exploited to dynamically manage multicast groups in 5G and mobile multicast environment. Also, mobile edge computing (MEC) is exploited to strengthen network control of 5G-SDMN.

Abstract:
Abstract Substantially growing data traffic over wireless networks poses increased challenges for mobile network operators in deploying sufficient network resources and managing user mobility. This dissertation considers these challenges to providing satisfactory Quality of Service (QoS) for end-users and studies solutions for better utilization of the heterogeneous network environment. First, the dissertation examines what solutions mobile devices and network management entities can use to dynamically collect valid cross-layer information from different network entities. Cross-layer information allows monitoring of the condition of the network in multiple layers on a user and application basis. The second research topic considers the techniques the network management entities can use to improve resource usage in wireless networks based on the collected cross-layer information. The IEEE 802.21 standard, specified to facilitate handovers between heterogeneous networks, is used as the basis for cross-layer information delivery. This dissertation also focuses on utilization of the standard beyond the inter-access technology handovers. In order to improve resource usage in wireless networks dynamically, event delivery enhancements are proposed for the standard so that it better applies to the requirements of different techniques. Such techniques are traffic priority adjustment, traffic adaptation, packet aggregation, and network protocol header compression. The results show that when a handover is not feasible, these techniques effectively allow sharing of the limited radio resources for the user data according to applications’ importance and type. Mobility management is studied in terms of network information service, one of the main services of IEEE 802.21. The thesis proposes enhancing the information service with a base station cell coverage area database. The database provides significant improvements for the selection of a handover target in a dense base station environment. With all the results taken together, the dissertation provides mobile network operators various means to improve the usage of wireless networks on the basis of applications’ varying QoS requirements
Tiivistelmä Voimakkaasti kasvava langattomien tietoverkkojen dataliikenne aiheuttaa verkko-operaattoreille haasteita tarjota riittävät verkkoresurssit ja hallita käyttäjien liikkuvuutta. Väitöskirja huomioi nämä haasteet tarjota loppukäyttäjille tyydyttävä palvelunlaatu (QoS) ja tutkii ratkaisuja, joilla heterogeenistä verkkoympäristöä voidaan hyödyntää tehokkaammin. Aluksi väitöskirja tutkii, mitä ratkaisuja päätelaitteet ja verkkohallintatoimijat voivat käyttää keräämään protokollakerrosten välistä (cross-layer) tietoa eri verkkotoimijoilta. Protokollakerrosten välinen tieto mahdollistaa verkon tilan seuraamisen usealla eri kerroksella käyttäjä- ja sovelluskohtaisesti. Toinen tutkimusaihe tarkastelee protokollakerrosten välistä tietoa hyödyntäviä tekniikoita, joita verkonhallintatoimijat voivat käyttää tehostamaan resurssien käyttöä langattomissa verkoissa. IEEE 802.21-standardia, joka on määritetty helpottamaan verkonvaihtoja heterogeenisten verkkojen välillä, käytetään pohjana protokollakerrosten välisen tiedon jakelulle. Väitöskirjassa keskitytään standardin hyödyntämiseen myös muussa kuin verkkoteknologioiden välisen verkonvaihdon yhteydessä. Väitöskirja ehdottaa parannuksia standardin tapahtumatietovälitykseen, jotta se täyttäisi paremmin eri tekniikoiden asettamat vaatimukset dynaamisesti toteutettavista toimista langattomien verkkojen resurssikäytön tehostamiseksi. Nämä tekniikat ovat liikenteen prioriteetin muutokset, liikenteen adaptointi, pakettien yhdistäminen ja verkkoprotokollaotsikoiden pakkaus. Tulokset osoittavat, että kun tukiasema- tai verkonvaihto ei ole mahdollinen, nämä tekniikat mahdollistavat rajattujen verkkoresurssien jakamisen tehokkaasti sovellusten tärkeyden ja tyypin mukaan. Liikkuvuudenhallintaa tutkitaan verkkoinformaatiopalvelun, joka on myös yksi IEEE 802.21-standardin pääpalveluista, kautta. Väitöskirja ehdottaa, että informaatiopalvelua tehostetaan liittämällä siihen tietokanta tukiasemasolujen peittoalueista. Tietokanta tehostaa huomattavasti verkonvaihdon kohteen valintaa tiheissä tukiasemaympäristöissä. Kun väitöskirjan tulokset huomioidaan kokonaisuutena, väitöskirja tarjoaa verkko-operaattoreille useita tapoja tehostaa langattomien verkkojen käyttöä sovellusten vaihtelevien palvelunlaatuvaatimusten perusteella

The convergence of wireless networks both fixed and mobile with the Internet is creating a revolution in the way wireless networked resources interact with each other. This thesis is concerned with mobile networks and proposes to deal with the mobility management problems for the mobile computing devices in the next generation of multi-technologies integrated IP based mobile networks. In order to do this, a new distributed home agent approach for mobility management has been developed that harmonizes the concept of micro-mobility and macro-mobility management in order to enable seamless mobility management on different kinds of wireless network environment especially interaction with the legacy cellular network in which resources are limited and expensive. The major contribution of this thesis is three-fold. Firstly, this thesis proposes network access architecture and a distributed mobility management scheme, which enables the mobility of a mobile device in a cellular packet data network in order to reduce the latency and network traffic required to handle the mobility management functionality. A detailed design of the distributed mobility management scheme is presented for the implementation and the conceptual model is analysed. Secondly, simulation of the mobility management schemes using two different network simulation packages to enable a comparison of the simulator functionalities is presented. Finally, the results of the simulation and suggested future work are presented.

Abstract:
In order to provide full end-to-end IP based service, 3GPP proposes the concept of an IP based access network. Recently, multi-protocol label switching (MPLS) has begun deployment in the Internet backbone to provide traffic engineering. MPLS is also proposed as a transport option in the access network of next generation wireless networks. One of the critical problems associated with mobile networks is mobility management; thus, it is important to handle mobility management in an MPLS based access network. In this thesis, a domain-based MPLS mobility management scheme for wireless cellular networks, including label switched path setup when the mobile host first powers on and mobile host handoffs, is presented. A medium access control layer assisted packet recovery scheme is proposed to recover packet loss during handoff. In order to reduce the power consumption of the mobile host and signalling load in the access network, a paging server is introduced, which brings in a hierarchical structure in addition to the function of paging. Route optimization is proposed to handle situations when the two communicating parts are in the same domain, thus reducing communication delays and load on the access network. The performance of the MPLS-based mobility management scheme is studied in terms of UDP packet loss and TCP throughput. In addition, the performance of MPLS-based mobility management is compared with three other schemes for IP mobility management, Cellular IP, HAWAII, and Hierarchical Mobile IP.

Increasing number of sophisticated services provided by the current wireless communication systems have caused a significant transition from E-commerce to M-commerce. Enterprises have provided considerable new opportunities to promote their businesses accessible from small mobile devices such as personal digital assistant (PDA) or mobiles phones. These facilities are envisioned as the most convenient way of using M-commerce. Using such services from mobile phones or PDAs equipped with GSM/GPRS involve effective mobility management mechanisms in cellular networks¿a popular architecture for wireless networks. Success of such systems will largely depend on the reliable connection for the roaming users. Consequently, Quality of Service (QoS) provision is one of the most challenging issues in the heterogeneous wireless network-based m-commerce systems. Such m-commerce systems enable users to roam between different wireless networks operators and geographical areas while providing interactive broadband services and seamless connectivity. This paper presents an analytical framework to model scarce channels in any cell for maximizing channel utilization and efficient handling of handover requests. Typical numerical experiments are presented to validate the analytical solution against simulation to study the effect of bursty traffic upon the performance of the cell in any cellular networks.

Abstract:
Two-tier macrocell-femtocell network is considered an efficient solution to enhance area spectral-efficiency, improve cell coverage and provide better quality-of-service (QoS) to mobile users. However, interference and mobility management are considered to be the major issues for successful deployment of macrocell-femtocell network. In this thesis, a unified framework is developed for interference management, resource allocation, and call admission control (CAC) for two-tier macrocell-femtocell network. Fractional frequency reuse (FFR) is considered to provide both link-level and call-level QoS measures for mobile users. In this framework, joint resource allocation and interference coordination problem is formulated as an optimization problem to obtain design parameters for sectored FFR. The CAC problem is formulated as Semi-Markov Decision Process and Value Iteration Algorithm is used to obtain optimal admission control policy. Performance of this framework is evaluated through simulations. The performance evaluation results show that the proposed framework outperforms traditional non-optimized FFR scheme in two-tier network.

Abstract:
Fourth Generation wireless networking (4G network) is expected to provide global roaming across different types of wireless and mobile networks. In this environment, roaming is seamless and users are always connected to the best network. Moreover, 4G networks will be packet switched systems entirely based on the IPv6 protocol. The essentiality of Quality of Service (QoS) and the heterogeneous nature of 4G pose high demands onto the mobility management technology. Due to this, one of the most challenging research areas for the 4G network is the design of intelligent mobility management techniques that take advantage of IP-based technologies to achieve global roaming among various access technologies. In order to address the issue of heterogeneity of the networks, IEEE 802.21 working group proposed Media Independent Handover (MIH). The scope of the IEEE 802.21 MIH standard is to develop a specification that provides link layer intelligence and other related network information to upper layers to optimize handovers between heterogeneous media. The IEEE 802.21 group defines the media independent handover function that will help mobile devices to roam across heterogeneous networks and stationary devices to switch over to any of the available heterogeneous networks around it.

Abstract:
Dynamic location of mobile users aims to deliver incoming calls to destination users. Most location algorithms keep track of mobile users through a predefined location area. The design of these location algorithms is focused to minimize the generated signaling traffic. There are three basic approaches to design location algorithms, namely distance-based, time-based and movement-based. In this Chapter we focus only on the movement-based algorithm since it achieves a good compromise between complexity and performance. We minimize a cost function for this dynamic movement-based location algorithm in order to find an optimum threshold in the number of updates. Counting the number of wireless cell crossing during inter-call times is a fundamental issue for our analysis. We use renewal theory to capture the probabilistic structure of this model, and it is general enough to include a variety of probability distributions for modeling cell residence times (CRT) in exponentially distributed location areas and hyperexponentially distributed intercall times. We present numerical results regarding some important distributions.

Abstract:
Existing mobility support models in cellular communications misinterpret mobility loss in cellular networks as congestion loss, thus it degrades the performance by invoking unnecessary congestion control action. In this paper, we investigated the performance of Double Buffer Technique (DBT) model for mobility support in wireless IP networks. The DBT model uses the END message and the TQRS timer to maintain the packet sequence and decrease the load on the new foreign agent when the timer expires, respectively. Also, the protocol showed improved performance degradation caused by the handover of the mobile terminal. In order to demonstrate the superiority of our scheme over the existing ones, we used the following performance metrics: packet out-of-sequence, cell loss ratio, bandwidth overhead, and suitability for real-time services. The numerical results obtained revealed that the buffer size, the waiting time, and the packet loss probabilities in the model were suitable to the wireless IP environment.
