In this study, we evaluate the performance of three types of techniques, namely neural based, Kalman filter based and trilateration based techniques, having been proposed to tackle the problem of real-time mobile sensor node tracking in a wireless sensor network with passive architecture. To investigate the performance of the aforementioned techniques under real-world circumstances, a small-scale wireless sensor network is deployed in an environment prone to multiple noise sources, multi-path and signal attenuation phenomena. The network makes use of a 433 MHz MICA2 based Cricket platform, which is comprised of 6 Cricket motes, at least one of which is mobile. The network utilizes a passive architecture in which any mobile mote receives the Beacon signals to localize itself. Subsequently, a neural based approach is compared with a trilateration and a Kalman filter based technique. The results obtained corroborate the efficiency and advanced performance of the neural based approach.
