中文摘要：

针对无线传感器网络（WSNs）节点定位技术中未知节点覆盖率低、成本高的问题，采用移动信标节点技术，提出对高斯一马尔可夫移动模型（GMM）规划路径的优化策略，使信标节点更有效地在待测区域移动，提高对未知节点的覆盖率，并分析了不同参数对未知节点覆盖率的影响。仿真结果表明：此方法覆盖迅速、覆盖率高，能很好地适应大规模随机布撒节点的应用需求。

英文摘要：

Aiming at problems of low coverage rate and high cost existing in node localization technology of WSNs,moving beacon nodes technology is used, optimization strategy for path planning of the Gauss-Markov mobile model（GMM） is put forward, to make the beacon node moving more effectively in the detected region and improve coverage rate of unknown nodes, influence of coverage of different parameters on the unknown nodes is analyzed. The simulation results show that the proposed method covers the unknown nodes rapidly and has high coverage rate. And can well adapt to application requirement of large scale randomized nodes lavout_
