| 摘 要： | 无线传感器网络多对一的数据流使节点能耗不均衡，影响网络公平性，缩短了网络生存时间。该文提出一种AODV改进方案，通过改进RREQ协议帧，使节点的剩余能量值参与到路径中，优化RREQ洪泛传播。经J-Sim仿真证实，该方案能有效均衡网络能量消耗，改善网络流量的不均匀性，缓解热点区域问题，从而延长网络寿命。

| Abstract: | Energy of nodes is exhausted unbalancedly due to many-to-one data stream in wireless sensor network,which influences the network fairness and reduces its life span.An improved AODV scheme is put forward.By the alteration of RREQ protocol packets,the reserved energy of nodes is transported to the route and the flood transmission is also optimized.The simulation by J-Sim illustrates this scheme can effectively balance all the nodes' energy,amend the unbalanced problem of network flux,and prolong the network l... |
