摘要: 为了降低能耗,均衡网络开销,提出了一种高效节能的TSSM算法。该算法规定在网络初始化时进行簇的划分,以后各轮簇内的成员节点将不再发生改变,从而降低了多次生成簇的能量消耗;通过循环选举簇头节点来分散网络的开销;通过划分虚拟单元格以及规定非活动节点休眠,活动节点设定软、硬门限工作的方法,有效降低了网络冗余度;通过簇间多跳将距离网关较远节点的能耗分散到了网络中的其它簇头节点。仿真结果表明,TSSM算法更能有效利用网络资源,均衡节点能源的分配,在一定程度上延长了网络的生命周期。Abstract: In order to reduce energy consumption and balance network overhead, the paper proposed a TSSM algorithm with high efficiency and energy saving. The algorithm formulates network to be divided into clusters when it is initialized, and member nodes within each cluster will not change in subsequent rounds, which can reduce energy consumption of multiple clustering. It spreads network overhead through circularly electing cluster head node. It reduce redundancy of network effectively through dividing virtual cells, regulating non-active node sleeping and setting soft and hard threshold of active node. It makes energy consumption of nodes which are far from gateway spread to the other cluster head nodes in network through method of inter-cluster multi-hop. The simulation result showed that TSSM algorithm can make use of network resources more effectively, balance distribution of node energy and prolong lifetime of network.
