Research on Space Location System Based on WSN

This article presents a low-energy-cost space location system based on WSN technology by applying random sampling algorithm, this system can locate a person real time who holds sensor node and adopt a representation method based on random sampling, so that the location algorithm can represent arbitrary distribution. According to the comparison of the simulation results demonstrates that the movement trajectory acquired by this system is very close to the real movement trajectory, and the number of location errors does not rely on the number of sampling numbers very obviously.
