摘要
针对现有多路径路由协议AOMDV的不足,提出了适用于无线传感器网络的能量感知多路径路由协议IMEA。IMEA在建立链路不相关的多路径时能优先建立节点不相关的多路径,在主路径失效时能优先选择与主路径共用节点最少的作为次优路径,而能量感知的路径选择策略能均衡网络中节点的能量消耗,实现数据传输路径的低能耗。对IMEA进行了仿真实验,结果表明IMEA有效延长了网络的生存时间。
According to the existing multi-path route protocol AOMDV＇ s drawback, the IMEA is presented （improved multi-path routing protocol with energy-aware based on AOMDV） which works well in the wireless sensor network. IMEA gives priority to the establishment of the node-disjoint multi-path when established the link-disjoint multi-paths and gives priority to the selection of the second best path which shares lest nodes with the main path when the main path does not work. The path selection strategy of energy-aware has balanced the energy consumption of nodes in the network and realized the low-energy consumption of data transmission. The simulation performance of IMEA is analyzed and results show that IMEA can prolong the network life time effectively.
