In this study, we propose a novel mobile tracking method based on Multi-Criteria Decision Making
(MCDM), in which uncertain parameters such as Pilot Signal Strength (PSS), the distance between
the mobile and the base station, the moving direction, and the previous location are used in the
decision process using the aggregation function in fuzzy set theory. In the microcell- or
picocell-based system the frequent movements of the mobile bring about excessive traffics into the
networks. A mobile location estimation mechanism can facilitate both efficient resource allocation
and better Quality of Service (QoS) provisioning through handoff optimization. Through numerical
results, we show that our proposed mobile tracking method provides a better performance than the
conventional method using the received signal strength.
