摘　　要：减少传感器节点的能量消耗,延长网络生命周期是无线传感器网络路由协议的首要设计目标。针对LEACH协议在簇的形成过程中节点只考虑自身的通信代价的不足,提出了一个基于权值的新协议,它融入了簇头的剩余能量以及簇头到基站的距离等因素。仿真实验表明,新的协议减少并平衡了各节点的能耗,延长了网络的生存时间。Reducing the energy consumption of the sensor nodes and prolonging the lifetime of the networks is the primary goal for designing route protocol.Since the nodes only consider their own communication cost in the formation of the cluster in LEACH,this paper proposes a new protocol based on the weight,it concerns about the residual energy of the cluster head and the distance between the cluster head and the Base Station.The simulation results show that the improved protocol reduces and balances the energy consumption of the nodes,also prolongs the lifetime of the networks effectively.
