  Localization of mobile nodes in a wireless sensor networks (WSNs) is an
active area of research. In this paper, we present a novel RSSI based
localization algorithm for 802.15.4 (ZigBee) based WSNs. We propose and
implement a novel range based localization algorithm to minimize cross
technology interference operating in the same band. The goal is to minimize the
mean square error of the localization algorithm. Hardware implementation of the
algorithm is in agreement with ideal (no interference) simulation results where
an accuracy of less than 0.5m has been achieved.
