基于事件驱动的采煤工作面动态空间无线传感器网络路由协议研究

Research of routing protocol for wireless sensor network in dynamic space of coal face based on event-driven

针对无线传感器网络节点随采煤工作面移动不断动态变化的问题,提出了一种基于事件驱动的动态成簇路由协议。该协议根据节点的剩余能量和事件对节点的刺激程度来选取事件区域内的簇头节点,并引入功率发射等级来确定成簇范围。仿真结果表明,该协议对突发事件区域内信息融合更为合理,数据链路传输速度更快,可有效降低网络能耗。

In view of problem that wireless sensor network node dynamically changes with coal face moving forward, the paper proposed a dynamic clustering routing protocol based on event-driven. The protocol chooses cluster head node in event area based on residual energy and excited intensity of node, introduces power emission levels to determine clustering range. The simulation results show that fusion information of emergent event area of the protocol is more reasonable, transmission speed of data link is faster, which can reduce energy consumption of network effectively.
