摘要
为了进一步提高井下无线传感器网络待测节点定位精度,文章提出了将节点定位算法和遗传算法结合在一起的基于遗传算法的节点定位算法,通过迭代寻优,提高定位精度。该算法是一种基于距离的三边测量定位算法,根据待测节点到信标节点的距离推测出待测节点的坐标。实验结果表明,该算法具有更高的定位精度。
To further enhance the location precision of unknown nodes in wireless sensor networks,a location method based on genetic algorithm is presented: the combination of wireless sensor network and genetic algorithm.It can improve positioning accuracy through iterative optimization.The method is dependent on distance,which can get the coordinates of the unknown node through the distance of unknown node and known node.Finally,the result is better.
