Location Based Channel Resource Allocation for V2V Communications

This paper proposes a channel Resource Allocation (RA) scheme based on location information for Vehicle-to-Vehicle (V2V) communications. The fast time-varying character of the wireless channel makes the channel resource allocation of V2V communications a challenging problem. However, the wireless channel, between the transmitter and the receiver depends on their locations, which are slowly changing. It is better to take the location information into consideration for the channel allocation scheme of V2V. Therefore, we propose a novel location-based RA scheme to maximize the system energy efficiency of both Cellular User Equipments (CUEs) and Vehicular User Equipments (VUEs). Simulation results show that the algorithm effectively improves the energy efficiency of CUEs and VUEs, reducing the algorithm's computational complexity in a large number of user scenarios.
