摘要
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.
This paper is a performance analysis of two node deployment strategies proposed for Wireless Sensors Networks.One is random node deployment strategy and the other is optimal node deployment strategy to achieve four connectivity and full coverage.Extensive simulations are made on different scenarios where different ratios of sensors′ communication range（denoted by c） to their sensing range（denoted by rs）.A novel simulation model is used to study two node deployment strategies and their performance implications.This experience not only presents the results of the optimal node deployment strategy can provide significant benefits to WSNs in terms of minimize cost and communication overhead,but also the performance differentials are analyzed using varying network topology in terms of degree of coverage,degree of network connectivity,and routing performance metrics.
