基于虚拟网关节点的采空区无线传感网络控制协议

Control Protocol of Wireless Sensor Network in Goaf Based on Virtual Gateway Node

煤矿采空区无线传感网络(WSN)是一种特殊的传输空间,存在时空变化性。目前应用于煤矿采空区的WSN路由算法监测效率不高。针对煤矿采空区监测时不断有新节点加入,旧节点逐步失去监测意义的实际情况,提出了一种基于虚拟网关节点的混合算法。该算法捆绑多个节点作为一个虚拟节点工作,集成了分层结构与平面网络的优点,增加了采空区网络的生存时间。

Coal mine goaf wireless sensor network(WSN)is a special transmission space,which has temporal and spatial variability.At present,WSN routing algorithm used in goaf monitoring efficiency was not high.In view of the fact that new nodes were constantly added and old nodes gradually lost the significance of monitoring,a hybrid algorithm based on virtual gateway node was proposed.The algorithm combined the advantages of hierarchical structure and planar network,and increased the survival time of goaf network.
