摘要:节点部署是无线传感器网络(WSN)研究的一个基本问题,如何进行合理的节点部署,是提高网络工作效率、优化利用网络资源的关键所在。针对WSN中覆盖、连通与节点布置等方面存在的问题,在现有正六边形网格划分的基础上,提出了一种基于泊松分布的节点部署方法,并利用Matlab软件进行了仿真。仿真结果表明,该模型不仅能够实现任意期望的连通覆盖,还能够在较小密度的节点分布下实现网络的无缝覆盖,保持网络的连通。

Abstract: One fundamental issue in wireless sensor networks(WSN) is sensor deployment, which affects the performance and effectiveness of WSN. Aiming at the problems of connectivity, coverage and sensor deployment in the WSN, based on the method of regular hexagonal grid plot for WSN, a node based on Poisson distribution was presented. This approach was implemented on Matlab software. The simulation results show that the model can achieve the partial coverage with any expectant percentage,achieve seamless network coverage in the deployment of the smaller node density, and maintain the network connectivity.
Key words: wireless sensor networks(WSN); grid; connectivity; Poisson distribution; coverage optimization
