Abstract：The three-dimensional spatial target localization based on wireless communication and networking technology is a hot research topic in the field of Internet of Things.However,there are still some problems including location is not accurate enough,the calculation overhead is too high and power consumption is too large.Thus,a distributed three-dimensional localization mechanism for the environment of the Internet of Things is proposed.The algorithm use Cooperative Location-Sensing(CLS) to mesh grid and determine the target location by the estimated distance.It combines Gaussian fitting ,signal sorting mechanism and Bounding-inbox algorithm which have effectively reduced signal interference.Moveover,it use local meshing to reduce the grid voting overhead.Simulation results show that the algorithm is better than the existing three-dimensional localization algorithm in positioning accuracy and have a lower power consumption.
