Filter design by using map information on Wireless-LAN location awareness system

Technologies to identify people and determine their positions are developing rapidly day by day. Many means exist to estimate a person´s position. Mainly, wireless sensors are used. Nevertheless wireless sensors have problems in accuracy. Because of multipath problem, wireless sensors cannot actually measure one´s position as the level of their specifications. This causes some fatal problems to estimate an area where person is. In this paper, we present a way to improve position information by filtering data which was obtained by a wireless location awareness system. We also show designed filter which is based on particle filter is effective by simulations and experiments.
