摘要: 无线传感器网络中节点的能量主要由电池供给,其能量严重受限。因此,设计新的更加节能的协议来支持无 线传感器网络的运行,使网络的有效生存时间尽可能延长成为研究的热点之一。针对延长无线传感器网络的有效生 存时间这一问题,展开以下两个方面的研究:第一,对传统的最大连通度分簇路由协议进行改进;第二,对LEACH协 议中形成非簇头节点选择最优簇的算法进行改进,使节点在加入簇头时综合考虑距离和能量两方面的因素,实现负载 均衡,从而延长网络的生存周期。仿真结果显示,新方法提高了传感器网络的能效,延长了系统的工作寿命。

Abstract: hhe nodes in wireless sensor networks energy is supplied by the battery, and the energy is very limited. hherefore,we need to design more energy-efficient wireless sensor network protocols to support the operation of the network as much as possible extend the effective lifetime of the current study to become one of the hotspots. This wire- less sensor networks extend the effective lifetime of the issues in the following two aspects; Firstly, we improved the protocol about, number(ID). Second, based on the LEACH protocol, we proposed an optimal algorithm for the non-clus- to head nodes to choose the best cluster. The new algorithm considers both the current energy of the cluster-head and the distance when the non-cluster head node determines its cluster. I3y balancing energy depletion over the whole net- work,simulation results show that our algorithm outperforms LEACH protocol and prolongs the network lifetime.
