摘要
煤矿智能救援系统,通过井下无线传感器网络监测数据,为系统提供安全预警支持。由于井下巷道错综复杂,不同的节点部署方法会影响井下监测数据传输的可靠性。为了节省无线传感器网络资源及维持网络的可靠通信,提出一种分级部署无线传感器网络节点方法,主干网节点采用最大通信距离算法部署,备用节点采用分级部署方法。仿真结果表明该方法有助于提高网络通信的可靠性,延长网络寿命,提升网络健壮性。
In coal mine intelligent rescue system, the monitoring data is used to provide support for the safety early warning by the underground wireless sensor. The underworkings are complex, so dif- ferent methods of nodes deployment will have influence on the reliability of underground monitoring data transmission. In order to save the wireless sensor network resources and maintain the reliability of network communication, the paper proposes a kind of hierarchical deployment method, backbone nodes are deployed through the maximum communication distance deployment algorithm and spare nodes are deployed through hierarchical deployment method. The simulation results show that the method helps to improve the reliability of the network communication, prolongs the network lifetime and improves the network robustness.
