摘要
近年来,随着对无线传感器网络研究的不断深入,节点定位问题受到了国内外研究者的极大关注。在深入研究无线传感器网络节点定位和模拟退火算法的基础上,提出了一种新颖的无线传感器网络节点定位算法,着重介绍了算法的基本原理和实现方法。仿真实验结果表明,该算法取得了良好的定位效果。该算法设计简单,计算量小,比较适合于无线传感器网络的节点定位。
In recent years, the problem of node localization has attracted much attention from researchers both at home and abroad while the wireless sensor networks become the focus for study. Based on an in-depth study of node location of wireless sensor networks and simulated annealing algorithm, this paper presents a novel node location algorithm. In this paper, the basic principle and the imp.lementation of the algorithm is emphatically described. Simulation results indicate that this algorithm has acquired good position performance. Since the algorithm is very simple and the computational loads are very small, it is suitable for node location of wireless sensor network.
