Firstly, an analytical model of the scenario will be developed for a given network topology and user demand. The objective will be to determine the minimum set of WiFi-based mesh Access Points and backhauls that can satisfy the demand subject to some resource usage constraints in order to reach a good understanding of how traffic demands, network topology and amount of receivers are related. Following this initial analytical work, a simulation based approach will be employed to determine how dynamic application-level multicast tree construction mechanisms can work to announce location-based and infotainment services. Also, these latter services will be characterized in terms of traffic pattern and QoS requirements in or order to devise distributed mechanisms to support their delivery and mobility in the mesh network. Finally, different approaches will be investigated to complement the weak GPS signal in large cities using in-network support mechanisms. Once the analytical and simulation-based works are complete, the project members will implement and prototype a concrete mesh technology supporting automotive services.
