New Hybrid RSS-based Localization Mechanism For Underwater Wireless Sensor Networks

Majid Hosseini


Localization is an important stage in Wireless Sensor Networks (WSNs) in order to make the collected information meaningful. For Underwater Wireless Sensor Networks (UWSNs), received signal strength (RSS) has been used for distance measurement through the state-of-the-art Lambert function \cite{Hosseini2010}. In this work, a hybrid RSS-based localization mechanism is presented which is comprised of three different stages including initialization, distance measurement, and position estimation. The simulation results, from comprehensive simulations, demonstrate the accuracy and efficiency of the hybrid localization mechanism compared to other existing distance measurement technique like Time of Arrival.
