矿井无线传感器网络覆盖问题研究

Research of Coverage Problem of Mine Wireless Sensor Network

  • 摘要: 具体分析并比较了现有的三种矿井巷道网络结构:Line型结构、Meshroof型结构及Meshchain型结构;在Line型结构和Meshroof型结构的基础上,设计了一种2-覆盖、2-连通的Line-2型网络结构,优化了井下无线网络传感器节点的配置。仿真结果表明,Line-2型网络的覆盖冗余度比Meshroof型网络的覆盖冗余度低,且Line-2型网络结构更简单,能够更好地适应煤矿井下环境。

     

    Abstract: Three existing mine network structures of Line structure, Meshroof structure and Meshchain structure were analyzed and compared in details, and a Line-2 network structure of 2-coverage and 2-connectivity was designed to optimize configuration of underground wireless network sensor nodes based on Line structure and Meshroof structure. The simulation results showed that the coverage redundancy of Line-2 network is lower than Meshroof network, and Line-2 network has more simple structure, and better adaptability to coal mine environment.
