基于UT-邻接矩阵的水下传感器网络1-栅栏覆盖算法性能

摘要

The adjacency matrix-based 1-barrier coverage algorithm is applied to the underwater sensor net-works.That algorithm is deeply analyzed utilizing the attenuated disk senging model.The number of required sen-sors constructing 1-barrier coverage is studied under different constructing radius.The influence on the detection probability of the system using that algorithm exerted by the constructing radius and the signal to noise ratio is dis-cussed.The experimental results show that the adjacency matrix-based 1-barrier coverage algorithm can ensure the high detection probability and less number of required sensors constructing 1-barrier coverage at the same time.%基于UT-邻接矩阵的1-栅栏覆盖算法是一种适用于水下传感器网络的栅栏覆盖策略.采用圆盘衰减模型,对该算法进行了深入研究.首先,分析了该算法在构建半径不同时,所需的传感器数目.再分析了构建半径、信噪比对采用该算法的系统检测概率的影响.实验结果表明,UT-邻接矩阵的1-栅栏覆盖算法在保证较高的检测概率的同时,所需的传感器数目比较少.
