对无线传感器网络中存在的两种节点配置模型,随机节点配置模型和四连通全覆盖优化节点配置模型进行性能分析.根据通信半径(表示为rc)和感知半径(表示为rs)的不同比率,提出一种新的仿真方法,并对这两种配置模型在不同Ad Hoc路由协议下的性能进行分析.大量的实验结果表明,四连通全覆盖优化节点配置模型不仅能减少配置成本和通信开销,而且对于不同的网络拓扑,其覆盖度、连通度和多个网络性能指标都有较大的提高.
Two kinds of node configuration models, random node configuration model and four-connection full-coverage optimization node configuration model exist in WSN for performance analysis.According to different ratios of communication radius (denoted by rc) and perceived radius (expressed as rs) This paper proposes a new simulation method and analyzes the performance of these two configuration models under different Ad Hoc routing protocols.A large number of experimental results show that the four connected full coverage optimization node configuration model can not only reduce the configuration cost and communication overhead, And for different network topologies, its coverage, connectivity and multiple network performance indicators have greatly improved.
