摘要: 为提高煤矿井下局部网络抗破坏能力和自修复能力，本文研究了一种煤矿井下移动无线传感器网络(MWSN)的局部节点部署方法，通过采用提高区域节点部署密度和节点分级的方法提高局部网络的抗破坏能力，并对该部署方法下局部网络的初始覆盖率和灾后覆盖率和网络连通性进行了分析，结果表明该方法具有较好的抗破坏能力。同时本文还设计了一种针对局部网络的受损检测和修复算法，充分利用网络区间内的移动机器人节点实现网络检测和自修复，通过对一段连续模拟空间的仿真实验，验证了该算法具有较好的网络连通修复能力。

Abstract: In order to improve the coal mine’s localized network ability to resist damage and self-repairing capability, this paper studies a kind of the coal mine mobile wireless sensor networks (MWSN) localized node deployment method. By improving the deployment density of localized nodes and nodes classification, the anti-failure capability of localized networks is improved. The initial deployment method under localized network coverage and post-disaster coverage and network connectivity is analyzed, and the results show that this method has better ability to resist damage. At the same time, this paper also designs a damage detection and repair algorithm for localized networks. Using mobile robot nodes in the network interval to achieve network detection and self-repairing through the simulation experiment of a continuous simulation space, it is verified that the algorithm has a good network connectivity repair ability.
