Abstract

A reliable vehicle-to-vehicle (V2V) communication is essential for safe and highly automated driving system. The use of roadside relay stations (RSs) has been studied to assist the V2V communication and improve its reliability. However, its improvement is limited by possible packet congestion at RSs. In order to mitigate the packet congestion at RSs, in this letter, we propose a network coding based payload concatenation forwarding with a payload sorting and selection algorithm. Large-scale computer simulations confirm that the proposed scheme remarkably improves the reliability of V2V communications.
