non-orthogonal multiple access vehicle to vehicle vehicle to infrastructure subchannel assignment power control
To solve fast channel variations induced by the mobility of the vehicles and achieve effective and reliable vehicular communications, the non-orthogonal multiple access is applied to the vehicle to vehicle(V2V)pairs underlaid vehicle to infrastructure(V2I)users to solve the downlink resource allocation. A geographic position-based clustering algorithm for V2V users is proposed. The base station preassigns the channel resources and the Kuhn-Munkres algorithm is used to complete the channel assignment. Then, the verified particle swarm optimization(PSO)is adopted to achieve the optimal power allocation. The simulation results show that the proposed scheme outperforms the existing device to device(D2D)mechanism by improving the network connectivity, spectrum efficiency and data transmission rate.
