Abstract :
RSU-assisted VANETs should provide vehicles and mobile users with reliable safety applications as well as various non-safety services with different QoS levels. We present a dedicated multi-channel MAC plus a QoS-provision channel allocation scheme based on the EDCA channel throughput analysis to improve the QoS performance of non-safety services for the RSU-assisted centralized VANETs. Simulation results show that the proposed scheme outperforms the other two existing centralized MAC schemes.
