Performance Analysis of Full-Duplex Cooperative Communication in Vehicular Ad-Hoc Networks

:This paper evaluates the use of full-duplex nodes to increase the performance of a vehicular ad hoc network (VANET) composed of one transmitter, multiple full-duplex relays and one destination, where the best relay is selected to assist communication. With the use of full-duplex communication, it is possible to obtain a better use of the radio resources, eliminating the multiplexing loss of half duplex systems. We consider Nakagami-m fading, aimed at analyzing the schemes in scenarios with line-of-sight and where the channel condition is critical, for instance a sub-Rayleigh channel, which are typical propagation scenarios to model vehicular networks. Furthermore, the analysis includes the self-interference at the relay node. Results presented in terms of outage probability shown that the full-duplex scheme is suitable for improving communication over vehicular channels.
