基于负载均衡的VANET跨层贪婪路由算法

iming at the problem of unbalanced load of VANET nodes in GPSR, this paper proposes a cross-layer greedy routing algorithm based on load balance. In the algorithm, the routing parameters are divided into motion parameters and communication parameters. The motion parameters are used to filter out the stable candidate node set, while the communication parameters are used to select the next hop forwarding node. In the communication parameter selection, this paper combines the sending queue occupancy rate of the Mac layer and the refresh times as the reference factors of routing. The simulation results show that the proposed routing algorithm performs better than GPSR in terms of end-to-end delay and packet delivery ratio.
