Abstract :
This paper proposes a new approach to solve the localization problem in wireless sensor networks with received signal strength measurements by using delta method, when the transmit power is unknown. We transform the radio path loss model to an equivalent form in order to get an alternative optimization problem which is much easier to solve and the global optimization solution can be obtained. Simulation results show the effectiveness of this scheme in a certain non-cooperative localization scenario.
