An adaptive parameter estimation method for wireless localization using RSSI measurements

Abstract

In location-based service (LBS), it is important to determine the location of a mobile user more, exactly and efficiently. In case of a wireless network, such as IEEE 802.11, a method using a received signal strength indicator (RSSI) for each access point is advantageous because it does not require additional infrastructure and it is suitable for the simplification. However, this technique of localization is required to investigate the propagation environment to determine the location of mobile user in advance. We propose a method in which the parameters of the propagation environment are determined using only RSSI measurements obtained during localization. © 2011 Springer-Verlag.
