Internship proposal
A Cross layer solution to Improve Network Connectivity and Capacity in Cooperative Vehicular Networks using Distributed Wireless Network Coding
Context and object:
The Intelligent Transportation Systems (ITS) is a universal initiative whose objective is to add information and communication technology to transport infrastructure and vehicles. It aims to manage different factors in order to improve safety and comfort to drivers/passengers, and reduce transportation times and fuel costs. With the advances in wireless communications technology and positioning systems many applications could become a reality. Vehicular networks became though a basic part in ITS attracting more and more attention. Thus, in addition to the improvement of traffic safety as well as the reduction of traffic congestion and fuel consumption, a plethora of new applications such as mobile infotainment emerges. To facilitate both safety and non-safety applications, there is a necessity to integrate communications and computing technologies into vehicular and transportation systems. These result in various types of vehicular communications modes: vehicle-to-infrastructure (V2I), vehicle-to-roadside (V2R), and vehicle-to-vehicle (V2V).
In order for vehicular communication and networking technologies to be widely deployed, many research challenges still need to be addressed. These challenges are related to the characteristics of vehicular networks: a large range of medium-to-high velocities, predictable mobility patterns and frequent network partition, to name a few. So, among the different issues that need to be handled in order to cope with the above mentioned challenges we can quote the wireless coverage enhancement and capacity augmentation at the physical layer and the improved MAC and routing protocol to deal with the specificities of such networks. Indeed, augmenting the wireless coverage allows reducing network partitioning situations and once connectivity is available, maximizing the capacity usage is the target. This will be possible only if the physical, MAC and routing layers are revisited. In that frame, the objective of this internship is to design a cross-layer solution, involving physical, MAC and routing layers, to enhance the performances of vehicular networks. As a first step, the objective is to combine three novel concepts, namely multi-input multi-output (MIMO), cooperative relaying and wireless network coding (WNC), in order to reach coverage enhancement and capacity augmentation. These three novel concepts being introduced at the physical layer, the second step of this internship is to propose the necessary changes at the MAC and routing layers in order to take full advantage from the above mentioned relay-assisted MIMO network with WNC.
This new network architecture targeting vehicular networks, the final aim of this internship is to investigate its performance under vehicular mobility requirement. More precisely, the project will provide solutions through both theory and simulation, and aim to prove whether a higher QoS for wireless users is enabled or not when such cross-layer solution is used.
