摘要
研究了一维区域上的无线传感器网络覆盖问题,首先提出了一维区域上的传感器节点随机覆盖模型并给出了节点覆盖概率计算公式;其次研究了一维区域上的传感器节点发射半径的确定方法,理论证明了传感器节点发射半径应大于或等于2倍感知半径;最后讨论了一维区域覆盖数计算方法.仿真实验表明节点感知半径是影响节点覆盖率和覆盖数的主要参数.论文的研究结果可作为一维区域上传感器网络设计的技术参考.
The coverage problems of the wireless sensor networks on the one-dimensional region are mainly studied in this paper.Firstly,the one-dimensional random coverage model is processed for the sensor nodes on the one-dimensional monitoring region,and the formula is given to calculate the node covering probability.Secondly,the method of determining the launching radius of the sensor nodes is studied.It is proved theoretically that the launching radius of the sensor node should be greater than or equal to 2 times to the sensing radius.Lastly,the calculation of the covering number is discussed.Simulation results show that the sensing radius of nodes has significant impact on the covering number and the node covering probability.The result of the study can be the technical specification used in the designing of the sensor networks on the one-dimensional region.
