Description
Summary:Wireless Sensor Networks (WSNs) attract a large variety of applications. The physical localization of sensors is one of the fundamental tasks in such networks. This task is challenging due to technical and financial constraints of nodes that need sophisticated solutions. Existing satellite-based methods might be cost, require high-energy consumption with no guarantee of full coverage of that area. Therefore, other methods, which use the local connectivity information to deduce sensors position, provide an approximate or a relative localization. In this work, we propose a new localization protocol called SL-Free protocol (Self Localization protocol based range-free), which provides a fine localization for node. The main goal of this proposal is to give the most precised coordinates with less cost. The performance study shows that, SL-Free outperforms its peers in terms of precision and energy use.
