Resource Allocation for V2V-Enabled Vehicular Communications Based on Hypergraph Partition

In cellular networks that support Vehicle-to-Vehicle (V2V) direct communication, a new resource allocation algorithm based on hypergraph partitioning is proposed to solve the resource allocation problem of Vehicle-to-Infrastructure (V2I) uplink multiplexing, in order to obtain the best resource allocation and robust channel change. Under the interference of V2V, the large scale fading information of wireless channels that changes slowly is used to combine communication reliability and power control, and the optimization model of maximizing the channel capacity of V2I is established to meet the heterogeneous requirements of vehicle network services, and then the minimum capacity maximization is considered to provide more uniform capacity performance. Simulation results show that the proposed algorithm improves the channel capacity of V2V and the channel is more robust on the premise of ensuring the reliability of V2V communication.
