摘　　要：由于无线传感器网络节点能量有限,为均衡无线传感器网络节点之间的能量消耗,提高整体网络的生命周期,针对LEACH协议中簇首选举时未考虑节点剩余能量因素、随机分簇等不足,提出了一种改进的LEACH协议。改进的LEACH协议在簇首选举时,以节点的剩余能量作为重要参考依据,优化节点担任簇首的概率。仿真结果表明,与传统的LEACH协议相比,改进的LEACH协议达到了能量消耗均衡的目标,从而延长了网络的生存寿命。There is limited energy inside the wireless sensor network nodes. In order to balance the energy consumption among wireless nodes and extend the life cycle of the whole network, a revised LEACH protocol is proposed, with the consideration on residual node energy to address the shortage of random clustering when choosing the cluster-head in LEACH. The cluster-head is chosen by improved LEACH protocol mainly based on the remaining energy inside nodes, and the probability of a cluster-head with higher residual energy of a node is raised. Simulations reveal that improved LEACH protocol is better at balancing energy distribution among nodes and extending network life cycle than traditional LEACH protocols.
