Abstract (in Japanese) (See Japanese page) 
(in English) We have developed an adhoc wireless positioning network (AWPN) that can temporarily and easily provide a positioning area, even in indoor environments. An AWPN provides a network-side positioning capability on a wireless mesh network; i.e., the network is constructed by deploying wireless LAN access points (APs) in the positioning area. However, the positioning performance is not enough due to the fact that an AWPN is mainly intended to make its deployment and configuration easier. In this paper, we propose a multilateration-based localization scheme which can improve the positioning accuracy in network-side localization with terminal-originated RSSI variations. Moreover, we evaluate the effectiveness of the proposed scheme in an actual environment. As a result, the proposed scheme improves the accuracy for estimating the position of a fixed terminal over 13.4% as compared with an existing method, and reduces terminal-originated RSSI variations. In addition, we confirm that it can stably estimate the trajectory of a moving terminal.
