| 摘 要： | 针对城市环境下车载自组网的特点及AODV协议广播式路由探测的不足,采用贪婪转发的单播式路由探测和经典AODV协议的广播式路由探测相结合的路由探测方式,并且单播路由探测在选择下一跳转发节点时同时考虑贪婪转发和链路稳定两个因素,减少了广播帧的发送,提高了路由的稳定性。仿真实验表明,改进后AODV协议比经典AODV协议更加适合城市车载自组网。

| Abstract: | Considering the characteristics of VANET in urban traffic environment and the shortage of broadcast routing detection of the AODV protocol, proposes an improved AODV routing protocol, where the routing detection combines the greedy forwarding unicast routing detection with the broadcast routing detection of classical AODV protocol. Furthermore, selecting the next hop forwarding node in the unicast routing detection takes into account both the greedy forwarding and the link stability to reduce the broadcast frames and improve the routing stability. The simulation results show that the improved AODV protocol is more suitable for Urban Vehicular Ad Hoc Networks. |
