For wireless mesh networks has no support infrastructure and shows a highly dynamic feature, routing becomes a key problem to be solved. Data packets are transmitted on a path that had least hops in AODV protocol. It couldn't consider the path stability. When the node of wireless mesh networks moved quickly and the path had short lifetime, the path recovery and routing again is caused. It is a lot of network resource. For network performance, AODV_D that improvement of AODV based on DSDV is provided to improve AODV protocol in the paper. It used structuring a DSDV-based routing table driven technology to select the less hops but high stability path to send data packets. Static node activates AODV_D routing protocol, sports node can choose artificially to activate or not activate this routing mechanism. NS-2 simulation results show that AODV_D routing protocol can improve the delivery rate of data packets, reduce the average end to end delay and packet-loss-rate.
