It is widely used, a fixed network structure has been unable to meet the new needs of the application

Determine the location of the incident or the access to information is a sensor network node position one of the most basic functions. As the wireless sensor network research, their applications become more widespread, a fixed network structure has been unable to meet the new needs of the application, the introduction of  mcb circuit breaker  extends the wireless sensor applications, but it also brings technical challenges. Currently, the mobile node localization in wireless sensor networks has become one of the hot research. This paper first discusses the wireless  power transformers  node positioning the basic principles, review its own positioning algorithm for wireless sensor networks, performance evaluation and classification methods, and the current thinking based on Monte Carlo localization mobile node localization algorithm are summarized. Next, Monte Carlo  air circuit breaker algorithm for posterior density values ​​in the larger area of ​​the small number of samples, the algorithm requires a lot of samples in order to achieve better positioning effect, this paper proposes an approach based on Monte Carlo Voronoi diagram positioning algorithm (MCVD, monte carlo localization based on Voronoi diagram).
