摘　　要：针对AODV路由协议中无路由备份和路由维护的不足以及改进策略的单一性,提出一种利用RREQ报文中Reserved字段中的前两比特位对AODV路由协议进行扩展,即Improved-AODV。采用Improved_AODV有效地减少了节点间的平均时延,提高了收发包成功率。最后,建立数学模型分析,并通过OPNET14.5仿真证明了改进的AODV路由协议明显优于传统方案。AODV routing protocol suffers from some limitations in routing backup and maintenance as well as the unicity of its improving strategy.In light of these,we put forward the Improved-AODV,which makes use of the first two bits of Reserved field of RREQ message to extend AODV routing protocol.The adoption of Improved-AODV effectively reduces the average time delay between nodes and improves the success rate of packet receiving and delivering.In the end,we set up the mathematical model analysis and demonstrate through OPNET14.5 simulation that the improved AODV routing protocol obviously outperforms the traditional protocol.
