摘要

有效地降低能耗,延长网络生存时间一直是无线传感器网络的研究热点.分析了LEACH协议并提出一种改进算法,该算法通过控制网络内冗余节点休眠,采用中转节点转发较远节点的监测信息,以减少网络中的冗余节点个数和簇首的数据通信量.仿真结果表明:新算法能有效节约网络能量,平衡节点能耗,延长网络生存时间.%How to reduce the energy consumption of nodes effectively and prolong the lifetime of network is the hot topic for research on wireless sensor networks. The classic low energy adaptive clustering hierarchy protocol is analyzed. A novel algorithm is improved. The algorithm contrails the redundant nodes' sleeping and uses intermediary node to transfer further nodes' information,which aims to reduce the number of redundant nodes and data communication amount of cluster head. The energy consumption of network is reduced. The results of simulation show that the novel algorithm can save energy effectively,balance energy consumption of the nodes and prolong the network lifetime.
