Abstract

In recent years, the indoor positioning systems using the existing wireless local area network and Location fingerprinting schemes are the most popular system. The accuracy of the system is the most important indicator. In this paper we present experimental studies to emphasize on location error. Two experimentation stages are realized. The first one is based on selected reference points. The second one is based on precision indicators. The obtained results give more insights for environment parameters and their impact on location error. Finally, we propose an optimization algorithm to effectively increase the location accuracy.
