摘 要:针对矿井巷道结构狭长而造成无线传感器网络节点能耗不均的问题,提出了一种新的矿井无线传感器路由机制,即矿井非均匀分簇LBUC-M协议:构造一个新的阈值公式以一定周期选举候选簇首,以非均匀半径确定最终簇首,使得远离汇聚节点的簇数量少、簇内节点多,靠近汇聚节点的簇数量多、簇内节点少,从而减轻靠近汇聚节点的簇首节点转发数据的负担,达到负载均衡的目的。仿真结果表明,LBUC-M协议有效减小了节点能耗,延长了网络生命周期。In view of problem of undistributed energy consumption of nodes of WSN caused by narrow and long mine roadway, the paper proposed a new routing mechanism of mine WSN, namely LBUC-M protocol: constructing a new threshold formula to elect candidate cluster-head in certain cycle and determining final cluster-head by non-uniform radius to realize less clusters far away from sink node and more nodes in these clusters, and vise versa, more clusters near sink node and less nodes in these clusters, so as to reduce burden of data transmission of cluster-head nodes near sink node and get goal of load balancing. The simulation result showed that LBUC-M protocol effectively reduces energy consumption of nodes and prolongs life cycle of WSN.
