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。

Abstract:

This paper researches the AODV routing protocol,analyzes the multipath routing protocol,and puts forward an energy efficient multipath AODV routing protocol for wireless multimedia sensor networks.EEMP-AODV builds multipath from source node to destination node.In order to achieve load balancing and extend the entire network lifetime,it takes hop count and nodes' residual energy into account in route choice.EEMP-AODV avoids congestion by divide rate into multipath.Finally,NS2 is used to simulate the proposed routing protocol.The result shows EEMP-AODV routing algorithm has a significant improvement in congestion avoidance,real-time performance,throughput and lifetime.

Key words: wireless multimedia sensor networks;routing;energy efficient;multipath
