根据MANET中的AODV路由协议,采用跨层设计的方法,通过节点距离估计模块、延时发送模块和高效广播模块对AODV路由协议进行了改进,提出一种适用于传感器网络的CAODV路由协议。计算机仿真证明CAODV在保证网络数据成功传送率不下降的情况下,能在降低网络开销、减少路由建立时间等方面取得良好的性能。
Based on AODV (Ad hoc on-demand distance vector)routing protocol in MANET, using cross-layer designing, put forward a CAODV (cross-layer AODV ) routing protocol which was suitable in WSN. CAODV improved AODV by using module of node' s distance estimating, delaying transmission and efficient broadcasting. Computer simulations show that, CAODV decreases the routing overhead, reduces route setting time, and keeps the successful packet delivery rate of routing protocol at same time.
