On Composability of Localization Protocols for Wireless Sensor Networks

Realistic, complex, outdoor environments pose significant challenges for node localization in Wireless Sensor Networks. In spite of the fact that many elegant and clever solutions have been proposed, no robust localization system has emerged. This status quo is because existing solutions work well for single sets of assumptions which, however, do not always hold in complex environments. In this paper, the authors review the state of art for node localization in Wireless Sensor Networks and show how localization protocol composability has the potential to provide the robust solution that is needed.
