Abstract
Wireless mesh networks (WMN) is a new type of wireless access network that combines the advantages of wireless local area networks (WLAN) with those of mobile ad hoc networks (MANET). The localization of mobile nodes in WMN has not been paid much attention as of yet in comparison with that of WLAN and MANET. As an essential component of user mobility support, localization in WMN should be more accurate in order to meet the need of mobile users in WMN. In this paper, we propose a ring overlapping based localization algorithm (ROL) that is based on subtle partial range aware (SPRA) distance measurement method. The experiments show that our new algorithms receive better results than existing methods and can reduce localization error within 3 meters in buildings.
