| 摘 要： | 针对无线传感器网络对目标区域覆盖过程中会产生大量冗余节点,从而导致网络能量消耗过快以及节点覆盖的不完全性等不足,提出了一种基于优化点集覆盖算法.该算法利用高斯正态密度函数和覆盖区域的概率函数对点集进行优化,通过节点感知半径与节点数之间的定量关系给出满足一定覆盖率要求下最优节点集,进而优化了网络资源,提高了网络生存周期和...

| Abstract: | A coverage algorithm based on optimization node sets is put forward to solve the problem that large amount of redundant node in the coverage of target area in WSN lead to large consumption of network energy and incompleteness of node coverage.The optimized node sets under certain coverage requirement are presented through optimization of node sets by Gaussian normal density function and probability function in the target area and perception of node on the quantitative relation between radius and the node am... |
