摘要
本文探讨了连接与覆盖模型对矿用无线传感器网络工程设计的影响,一方面,采用概率统计和图论方法推导出了网络的覆盖率与网络节点数以及感知覆盖半径的关系模型表达式;另一方面,利用扩散理论及其仿真方法,分析得到了连接性与连接度的关系模型。大量仿真实验结果证明了提出的连接与覆盖模型有效性,包括网络节点连接可靠性、端到端连接性以及网络覆盖率。最后给出了矿用无线传感器网络覆盖规划设计的一般准则,对矿用无线传感器网络应用部署具有一定的实用参考价值。
The Impacts of Connectivity and Coverage Model on the Design of WSN in Coal Mine are focused and discussed. On the one hand,the formula of relationship model among network coverage ratio,number of nodes and sensing radius of nodes is obtained by stochastic and statistic methods as well as graph theory. On the other hand,the relationship model between the connectivity and connection degree is obtained. The extensive simulation results verified the validation of the proposed model of connectivity and coverage,including connection reliability of node,end-to-end connectivity,and network coverage ratio. Finally,the usual design criteria for coverage are proposed and it is very useful for deployment and appli-cation of WSN in Coal Mine.
