Abstract :
Power efficiency and accuracy are among the primary design requirements of the localization algorithms in wireless sensor networks. However, to the knowledge of the authors, there has been neither previous detailed study on the energy consumption of localization algorithms, nor previous algorithm that considers the power consumption as the main metric. In this paper, we propose a power-aware and range-free localization algorithm, LR-DV-hop algorithm, which can effectively reduce the communication overhead and energy consumption. It is shown in the simulation results that, our algorithm can save up to 50% power consumption of the classical DV-hop algorithm while achieve better localization accuracy
