Abstract

Localization is a key technology in wireless sensor network and localization in three dimensional environments is very popular and will be leading the future development of localization technology. This paper proposed a DCP3D (the degree of coplanarity three dimensional) algorithm which used the degree of coplanarity and multiple threshold constraint strategy to improve the accuracy by analyzing the beacon node topology. Simulation results show that the improved method has a good performance in accuracy, bad node control and stability.
