Abstract

The localization process in wireless sensor networks must produce precise positions at minimal requirements. It is hard to comply with these conditions, due to the strong resource limitation of each sensor node. Although numerous algorithms have already been presented, so far there exist neither an extensive simulative comparison of them nor a qualified parameter to indicate their efficiency. Thus, this paper introduces a selected number of the most important algorithms for sensor networks. These algorithms are compared with each other considering achieved localization error and consumed energy. Then, we propose an adequate parameter to quantify their efficiency - the "Power Error Product" (PEP).
