在低功耗自适应分簇( LEACH,Low Energy Adaptive Clustering Hierarch)算法中,由于每一轮循环都要重新构造簇,距离较远的簇头节点可能会因长距离发送数据而过早耗尽自身能量,能量较低的节点当选为簇头节点时将会加速该节点的死亡,影响整个网络的生命周期。针对LEACH算法分簇机制中存在的不足,提出了一种改进的路由算法。仿真结果表明,改进算法通过考虑节点的剩余能量与固定分簇的方法,有效的改善了网络能量均衡,提高了网络生存时间。

LEACH algorithm is the typical layered routing protocol of WSN, as it reconstructed clusters each loop,the distant cluster head nodes could be out of work easily owing to long-distance-sending data. When the distant node is selected to the cluster head one,it could accelerate the death of the nodes, disrupting the network life cycle. Aiming at the defect of the LEACH algorithm clustering mechanism, a kind of improved routing algorithm is proposed. Experimental result indicates that with the residual energy of node and fixed clustering, the equipoise of network energy could be improved, and the network lifetime increased.
