摘要
为了提高定位精度,提出了基于蚁群算法的井下无线传感器网络的定位算法,从而获得更高的定位精度。为了适应井下有限的硬件条件要求,采用不需外加硬件条件的DV-Hop算法获得节点间距离,从而由三边测量法确定未知节点位置。为了验证提出算法的可行性,通过MATLAB进行仿真验证,实验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 Ant Colony Algorithm is presented, which is optimize trilateration positioning error function with Ant Colony Algorithm. In order to meet the limited hardware conditions of underground, the distance between nodes is got by DV-Hop Algorithm, then get the unknown node by trilateration. In order to verify the feasibility of the proposed algorithm, it is verified by MATLAB and the positioning accuracy is better.
