摘　　要：根据LEACH协议提出一种改进的路由算法,利用能量和距离参数对簇头进行成链创建,既减轻了负载过重簇头节点的负担,又减少了能量消耗。通过MATLAB仿真实验验证,新算法比LEACH算法更加节约能量,同时延长了网络生命周期,提高了网络寿命。Due to the constrained energy of nodes in wireless sensor networks, how to reduce en- ergy consumption of nodes becomes an important target of routing protocols. A novel routing al- gorithm based on LEACH is proposed. In this routing algorithm, cluster head linked into chains is established by energy and distance parameters. As a result, the burden of overload cluster heads is eased and energy consumption of nodes is reduced. It is testified by MATLAB simula- ring that the new algorithm, compared with LEACH, can save more energy and prolong the net- work lifetime.
