The wireless LAN(Wi-Fi) infrastructure is widely used and many location-aware systems and services are researched. In this paper, wireless LAN based indoor positioning system WiPS is proposed. WiPS uses wireless LAN technology to measure the location of each mobile terminal. Mobile terminals equip only wireless LAN device to communicate and measure its location, so it can be made without any additional devices for location sensing. Existing wireless LAN based location systems measure the signal strength by only access points. On WiPS, each mobile terminal also measures the signal strength of neighboring terminals. Thereby WiPS can achieve more precise location estimation than existing systems, where there are many mobile terminals. We simulate the case that disntance measurement has probablistic error. The result shows improvement of accuracy in WiPS.
