In this paper, we propose a position estimation technique using directional antenna to assist users detecting wireless access points. In our technique, the system measures the current position of the user, the direction of the antenna and the recieved signal strength of the wireless access point periodically, and estimates the position of the wireless access point from accumulated data using the signal strength model based on directivity to assist the user in real-time.
