一种无线传感器网络能量感知路由协议

摘要

为延长无线传感器网络生命周期,将节点能量补充与节能路由相结合,在分簇网络的基础上提出一种能量感知路由协议MAPA-MIPC.利用太阳能作为能量补充方式,根据链路上每个节点的能量剩余、消耗以及预测的下一时刻太阳能的收集情况,计算出该节点数据的最佳上传路径.同时在簇首和中转节点选举时检查能量阈值,对于未达到阈值的节点不能成为簇首或转发节点,以确保簇首和能量低的节点具有更长的生命周期.仿真结果表明,与MRRCE和EHA-LEACH协议相比,MAPA-MIPC能够更好地延长网络生命周期.%In order to prolong the life cycle of wireless sensor network,this paper proposes an energy aware routing protocol MAPA-MIPC based on clustering network,which combines the supplement of nodes' energy and the energy saving routing.Using solar energy as an energy supplement,according to the energy remaining of each node on the link,consumption and prediction of the next moment of solar energy collection,it calculates the best upload path of the node data.At the same time,the energy threshold detection is introduced to the cluster head and the relay node election.Nodes that do not reach the threshold value cannot become a cluster head or a forwarding node,thus ensures that the cluster heads and the low energy nodes have a longer life cycle.Simulation results show that compared with MRRCE and EHA-LEACH protocol,MAPA-MIPC has obvious advantage in extending the network life cycle.
