Sensor localization is a fundamental and crucial issue for wireless sensor networks operation and management. In this paper, we present a new localization scheme with mobile beacon for wireless sensor networks. The scheme relies on TDoA (time difference of arrival) of the mobile beacon RF signals measured locally at a sensor to detect range differences from the sensor to the different position of the mobile beacon. We analyze the performance of our scheme and identify possible sources of position errors and suggested measures to avoid them. We conduct simulations to test the performance of our scheme, the obtained results show that the scheme is an effective scheme for localization in wireless sensor networks
