Multi-access Edge computing is an emerging paradigm within the Internet of Things (IoT) that complements Cloud computing. This paradigm proposes the implementation of computing servers located close to users, reducing the pressure and costs of local network infrastructure. This proximity to users is giving rise to new use cases, such as the deployment of mobile servers mounted on drones or robots, offering a cheaper, more energy-efficient and flexible alternative to fixed infrastructures for one-off or exceptional events. However, this approach also raises new challenges for the deployment and allocation of resources in terms of time and space, which are often battery-dependent.In this thesis, we propose predictive tools and algorithms for making decisions about the allocation of fixed and mobile resources, in terms of both time and space, within dynamic environments. We provide rich and reproducible datasets that reflect the heterogeneity inherent in Internet of Things (IoT) applications, while exhibiting a high rate of contention and interference. To achieve this, we are using the FIT-IoT Lab, an open testbed dedicated to the IoT, and we are making all the code available in an open manner. In addition, we have developed a tool for generating IoT traces in an automated and reproducible way. We use these datasets to train machine learning algorithms based on regression techniques to evaluate their ability to predict the throughput of IoT applications. In a similar approach, we have also trained and analysed a neural network of the temporal transformer type to predict several Quality of Service (QoS) metrics. In order to take into account the mobility of resources, we are generating IoT traces integrating mobile access points embedded in TurtleBot robots. These traces, which incorporate mobility, are used to validate and test a federated learning framework based on parsimonious temporal transformers. Finally, we propose a decentralised algorithm for predicting human population density by region, based on the use of a particle filter. We test and validate this algorithm using the Webots simulator in the context of servers embedded in robots, and the ns-3 simulator for the network part

Data stream processing and analytics (DSPA) applications are widely used to process the ever increasing amounts of data streams produced by highly geographically distributed data sources, such as fixed and mobile IoT devices, in order to extract valuable information in a timely manner for actuation. DSPA applications are typically deployed in the Cloud to benefit from practically unlimited computational resources on demand. However, such centralized and distant computing solutions may suffer from limited network bandwidth and high network delay. Additionally, data propagation to the Cloud may compromise the privacy of sensitive data. To effectively handle this volume of data streams, the emerging Edge/Fog computing paradigm is used as the middle-tier between the Cloud and the IoT devices to process data streams closer to their sources and to reduce the network resource usage and network delay to reach the Cloud. However, Edge/Fog computing comes with limited computational resource capacities and requires deciding which part of the DSPA application should be performed in the Edge/Fog layers while satisfying the application response time constraint for timely actuation. Furthermore, the computational and network resources across the Edge-Fog-Cloud architecture can be shareable among multiple DSPA (and other) applications, which calls for efficient resource usage. In this PhD research, we propose a new model for assessing the usage cost of resources across the Edge-Fog-Cloud architecture. Our model addresses both computational and network resources and enables dealing with the trade-offs that are inherent to their joint usage. It precisely characterizes the usage cost of resources by distinguishing between abundant and constrained resources as well as by considering their dynamic availability, hence covering both resources dedicated to a single DSPA application and shareable resources. We complement our system modeling with a response time model for DSPA applications that takes into account their windowing characteristics. Leveraging these models, we formulate the problem of scheduling streaming operators over a hierarchical Edge-Fog-Cloud resource architecture. Our target problem presents two distinctive features. First, it aims at jointly optimizing the resource usage cost for computational and network resources, while few existing approaches have taken computational resources into account in their optimization goals. More precisely, our aim is to schedule a DSPA application in a way that it uses available resources in the most efficient manner. This enables saving valuable resources for other DSPA (and non DSPA) applications that share the same resource architecture. Second, it is subject to a response time constraint, while few works have dealt with such a constraint; most approaches for scheduling time-critical (DSPA) applications include the response time in their optimization goals. To solve our formulated problem, we introduce several heuristic algorithms that deal with different versions of the problem: static resource-aware scheduling that each time calculates a new system deployment from the outset, time-aware and resource-aware scheduling, dynamic scheduling that takes into account the current deployment. Finally, we extensively and comparatively evaluate our algorithms with realistic simulations against several baselines that either we introduce or that originate / are inspired from the existing literature. Our results demonstrate that our solutions advance the current state of the art in scheduling DSPA applications

Network management is undergoing drastic changes due to the high expectations of the infrastructure to support new services. The diverse requirements of these services, call for the integration of new enabler technologies that complicate the network monitoring and planning process. Therefore, to alleviate the burden and increase the monitoring and planning accuracy, more automated solutions on the element/device level are required. In this thesis, we propose a semi-automated framework called AI-driven telemetry (ADT) for collecting, processing, and assessing the state of routers using streaming telemetry data. ADT consists of 4 building blocks: collector, detector, explainer, and exporter. We concentrate on the detection block in ADT and propose a multi-variate online change detection technique called DESTIN. Our study on the explainer block of ADT is limited to exploring the potential of the input data and showcasing the possibility of the automated event description. Then, we tackle the problem of planning and dimensioning in radio access networks equipped with distributed edge servers. We propose a model that satisfies the service requirements and makes use of novel enabler technologies, i.e. network slicing and virtualization techniques. We showcase the advantages of using our holistic model to automate RAN planning by utilizing simulated annealing and greedy methods

Mobile Edge Computing (MEC) is an emerging computing model that extends the cloud and its services to the edge of the network. Consider the execution of emerging resource-intensive applications in MEC network, computation offloading is a proven successful paradigm for enabling resource-intensive applications on mobile devices. Moreover, in view of emerging mobile collaborative application (MCA), the offloaded tasks can be duplicated when multiple users are in the same proximity. This motivates us to design a collaborative computation offloading scheme for multi-user MEC network. In this context, we separately study the collaborative computation offloading schemes for the scenarios of MEC offloading, device-to-device (D2D) offloading and hybrid offloading, respectively. In the MEC offloading scenario, we assume that multiple mobile users offload duplicated computation tasks to the network edge servers, and share the computation results among them. Our goal is to develop the optimal fine-grained collaborative offloading strategies with caching enhancements to minimize the overall execution delay at the mobile terminal side. To this end, we propose an optimal offloading with caching-enhancement scheme (OOCS) for femto-cloud scenario and mobile edge computing scenario, respectively. Simulation results show that compared to six alternative solutions in literature, our single-user OOCS can reduce execution delay up to 42.83% and 33.28% for single-user femto-cloud and single-user mobile edge computing, respectively. On the other hand, our multi-user OOCS can further reduce 11.71% delay compared to single-user OOCS through users' cooperation. In the D2D offloading scenario, we assume that where duplicated computation tasks are processed on specific mobile users and computation results are shared through Device-to-Device (D2D) multicast channel. Our goal here is to find an optimal network partition for D2D multicast offloading, in order to minimize the overall energy consumption at the mobile terminal side. To this end, we first propose a D2D multicast-based computation offloading framework where the problem is modelled as a combinatorial optimization problem, and then solved using the concepts of from maximum weighted bipartite matching and coalitional game. Note that our proposal considers the delay constraint for each mobile user as well as the battery level to guarantee fairness. To gauge the effectiveness of our proposal, we simulate three typical interactive components. Simulation results show that our algorithm can significantly reduce the energy consumption, and guarantee the battery fairness among multiple users at the same time. We then extend the D2D offloading to hybrid offloading with social relationship consideration. In this context, we propose a hybrid multicast-based task execution framework for mobile edge computing, where a crowd of mobile devices at the network edge leverage network-assisted D2D collaboration for wireless distributed computing and outcome sharing. The framework is social-aware in order to build effective D2D links [...]

This thesis is intended to meet the expectations of the scientific community and the needs of Cloud operators on network insolation in a virtualized datacenter. It focuses on the layer 2 scaling in order to better identify the locks and the opportunities on the modern virtualized datacenter networks. First, it presents a new algorithm for dynamic bandwidth allocation at the physical nodes in order to overcome the problem of internal denial of service attacks while respecting all tenants SLA. Second, it uses an adaptation of TRILL (RFC 6325) switches, called RBridge on physical nodes within a virtualized data center, thus enabling to address the layer 2 scalability problems. Finally, it proposes a new mechanism called VNT (Virtual Netwotk over TRILL), allowing flexible logical networks creation. This mechanism, which includes a new identifier VNI (Virtual Network Identifier), allows the coexistence of more than 16 million logical networks within the same physical network

Computation offloading is one of the most promising paradigm to overcome the lack of computational resources in mobile devices. Basically, it allows the execution of part orall of a mobile application in the cloud. The main objective is to reduce both execution time and energy consumption for the mobile terminals. Unfortunately, even if clouds have rich computing and storage resources, they are usually geographically far from mobile applications and may suffer from large delays, which is particularly problematic for mobile applications with small response time requirements. To reduce this long delay, one of the emerging approach is to push the cloud to the network edge. This proximity gives the opportunity to mobile users to offload their tasks to “local” cloud for processing. An Edge Cloud can be seen as small data center acting as a shadow image of larger data centers. This geographical proximity between mobile applications and edge cloud means that the access delay can be greatly reduced, but affects also higher throughput, improved responsiveness and better scalability. In this thesis, we focus on computation offloading in mobile environment (Mobile Edge Computing - MEC), composed of several edge servers. Our goal is to explore new and effective offloading strategies to improve applications performances in both execution time and energy consumption, while ensuring application requirements. Our first contribution is a new offloading strategy in the case of multiple edge servers. Thenwe extend this strategy to include the Cloud. Both strategies have been evaluated theoretically and experimentally by the implementation of an offloading middleware. Finally, we propose a new elastic approach in the case of multitasking applications characterized by a graph of dependencies between tasks
