中文摘要：
提出了一种将有线工业以太网和WSN有机结合的矿井监控与应急通信系统,结合该系统的应用要求,设计了一种基于分层的工作面路由协议（LRWF,Layer-based Routing for Working Face）。LRWF利用分簇的思想,将工作面节点按照跳数分层后,根据各层的不同负载形成不同规模的簇以便均衡网络能量,之后以簇首间时变的传输延时、节点剩余能量和传输能耗构建的复合指标选取路径,实现簇间数据的多跳转发。OMNET＋＋仿真实验结果表明,LRWF与现有的矿井WSN路由协议相比,具有较低延时和更好的能量有效性,更适合于矿井环境。
英文摘要：
A mine monitoring and emergency communication system combining Ethernet and WSN was we put forward. Combined with the application demands of system,a Layer-based routing for working face was designed. LRWF will first divide the monitoring area into different layers,and according to the different data load of layers,formulate different size clusters to balance the network energy,and then based on the time-varying discovery delay,residual energy and communication cost to build compound index for choosing road,realizing the data transmission between clusters. Finally,with the application of OMNET ＋ ＋ software,LRWF has lower latency and better energy efficiency than other existing WSN routing protocol for mine,and is more suitable for the mine environment.
