[Abstract]:Aiming at the problem that there are more vehicles, faster moving speed and fixed road topology in urban scenarios, the communication performance of VANET routing protocol is greatly degraded. A city cross-layer multi-hop geography routing protocol (city cross-layer multi-hop geography routing CCMGR) based on geographical location is proposed for urban scenarios. The protocol synthetically considers the mobile information and physical layer of the vehicle and the cross-layer information of the data link layer as the weight of data forwarding. The node selection algorithm and the weight decision method are proposed to transmit the data to nodes with small dynamic selection value. Simulation results based on NS-3 network show that the CCMGR routing protocol is superior to the GPSR-DSDV OLSR and DSR protocols in data transmission success rate and end-to-end average delay performance, and is suitable for urban VANETs.
