Abstract

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. Pseudorange observation data of global positioning system (GPS) and distance observation data of WSN are utilized to carry out positioning. Simulation results show that comparing with traditional GPS location algorithm, adaptation range is increased and positioning with less than four satellites is realized using the algorithm; and comparing with WSN location algorithm, the algorithm has a higher precision.
