摘　　要：基于矿井巷道等狭长区域的地理特征,提出了一种无线传感器网络(WSNs)的能耗均衡部署策略(EDNU).将狭长WSNs抽象成线性链状网络,分成等距的若干区间段,在整个线性链状网络中部署感知节点、通信节点和数据汇集节点(Sink)共3种设备.感知节点在每个区间段内部署数量是相等的;通信节点的部署数量在各个区间段内是不等的,并且从最外层区间段向内层Sink节点的靠近过程中,数量呈等差方式递增.结果表明:EDNU可以实现通信节点能耗均衡,解决狭长区域中WSNs能量空洞问题,延长了整个网络的生命周期,并且可通过调整各区间段的通信节点数量来适应矿井巷道长度的动态变化.ased on the geographical characteristics of the mine roadway and other long-narrow regions,an energy-balancing deployment strategy named EDNU of wireless sensor networks（WSNs）was proposed.Long-narrow WSNs were depicted as linear chain network with several equidistant segments,and three types of devices including sensor nodes,communication nodes and sink nodes were distributed along the entire network.Equal numbers of sensor nodes were deployed in each segment while incremental numbers with arithmetic sequence of communication nodes were deployed in segments from the segment far away the sink node to the nearest one.It was theoretically proved that EDNU strategy can achieve a balance in energy consumption,and overcome the problem of energy hole of WSNs in long-narrow region,also prolong the life cycle of the entire network.In addition,the number of communication nodes of each segment can be adjusted to fit the dynamic length changes of the mine roadway.
