摘　　要：在无线传感器网络应用当中,位置数据向来是关键信息之一。怎样用最小的代价,使得定位算法更加稳定健壮、更精确、更高效,是目前无线传感网定位算法追求的一个方向。因为无线传感网络有着很强的应用相关性,Monte-Carlo中心定位算法以井下环境为背景,设计的一种基于Monte-Carlo算法的改进的定位算法,定位方法简单,定位计算量小。最后通过实验将该算法和Monte-Carlo算法进行了仿真,结果显示在井下环境条件下,该算法有很强的稳定性和更好的精度。For most wireless sensor network applications, position data is one of key information. How to make the positioning algorithm more stable and robust, more accurate, more efficient with the minimum cost is a direction which wireless sensor net- work localization algorithm to pursue. Applications of wireless sensor network are attached great relevence to application. It takes tunnel environment as the background, designs an improved localization algorithm based on the Monte-Carlo localization （Center Monte-Carlo Location, CMCL）, CMCL method is simple and uses bitty computation. Compared and analyzed the CMCL and Monte-Carlo localization though the experiment of simulation, the result reveals that the CMCL has strong stability and better accuracy.
