摘　　要：节点定位问题是无线传感器网络中的最重要的基本问题之一。通过引入和声搜索算法来优化无线传感器网络中的节点定位计算,降低了测距误差的影响,提高了节点的定位精度;减少了计算的复杂度,加快了运算速度。仿真实验中通过与基于模拟退火、遗传算法的求解方法进行比较,结果表明定位计算技术在定位精度、运行性能方面的效果较好。Node localization in wireless sensor networks is one of the most important basic problems. By introducing harmony search algorithm to optimize the wireless sensor network node position calculation, it reduces the impact of ranging error and im-proves the positioning accuracy node. It also reduces the computational complexity and accelerates the speed of operation. By compared the simulation experiment to the solving methods based on the annealing and genetic algorithms, the results show that the positioning computing technology of this paper are better in positioning accuracy, operational performance.
