在矿井中布署无线传感器网络可以提高应对突发事件的能力,而能量消耗是无线传感器网络路由协议设计中需要考虑的首要因素。针对LEACH协议中存在问题,设计了一种基于分簇的路由协议,改进了簇头选择与分簇算法,采用最小生成树算法来减少簇头节点的能量消耗,并通过仿真实验验证了新协议的性能改进。
Deployed wireless sensor networks in underground mines can improve the ability to handle emergencies.Energy consumption is first issue to be considered for routing protocol of wireless sensor networks.Aimed to the problem of LEACH,a new cluster routing protocol is presented,which improves the algorithm of selection cluster head and creating cluster and reduces energy consumption of cluster head using minimum spanning tree algorithm.The simulation results show performance improvement of new protocol.
