针对城市道路车辆密集和路侧节点间隔较小的特点，利用路侧节点覆盖范围大的优势，借助了节点定期发送心跳信息的机制，通过在路由建立阶段提高路侧节点的选择优先级、周围节点队列本地查找、心跳信息用于路由维护等方法，对传统AODV算法进行了优化。仿真结果显示，优化后的效果明显。

The vehicular communication need simple and quickly convergence routing protocol because of the fast moving of the on board units (OBU). Base on the characteristics of vehicle density and smaller in-tervals between road side units (RSU)on city roads, this paper presents a AODV optimization method ex-ploiting the advantage of REU on long range covering and the periodicbroadcast heartbeat information among the nodes. Compare to the traditional AODV, this method raised the choice priority of the RSU, next ship node finding in local queue in routing establish-ment, and utilize the heartbeat information to route maintenance.The simulationresultsindicate obvious im-provement of optimization.
