A Location Algorithm Integrating GPS with WSN in a Pervasive Computing Environment

An integrated location algorithm using satellite location and wireless sensor networks(WSN)is put forward to solve the issues of seamless location both indoors and outdoors in a pervasive computing environment in this paper.A global positioning system(GPS)integrating observation data with WSN distance observation data is utilized to carry out location compute.Simulation results show that comparing with traditional GPS location algorithm,adaptation range is increased and location with less than four satellites is realized using the algorithm.
