摘要
研究了AODV路由协议,分析了多路径路由实现机制,提出了一种可应用于无线多媒体传感器网络的能量均衡多路径AODV路由协议。该协议建立从源节点到目的节点的多条路径,在路径的选择上综合考虑了路径跳数和节点剩余能量,用以保证负载均衡,延长网络生存期,该算法使用了分流的方式避免拥塞。通过使用NS2仿真软件对EEMP-AODV路由协议进行仿真,结果显示其在拥塞避免、实时性、吞吐量和网络生存期方面的性能有明显提升。
This paper researches the AODV routing protocol, analyzes the muhipath routing protocol, and putsforward an energy efficient multipath AODV routing protocol for wireless multimedia sensor networks. EEMP-AODVbuilds muhipath from source node to destination node. In order to achieve load balancing and extend the entire net-work lifetime, it takes hop count and nodes＇ residual energy into account in route choice. EEMP-AODV avoids con-gestion by divide rate into multipath. Finally, NS2 is used to simulate the proposed routing protocol. The resultshows EEMP-AODV routing algorithm has a significant improvement in congestion avoidance, real-time performance,throughput and lifetime
