Abstract: 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 network 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.
