摘要：

Sensor localization is a fundamental and crucial issue for wireless sensor networks operation and management. In this paper, we present a new TDoA-based localization scheme for wireless sensor networks. The scheme relies on TDoA (Time Difference of Arrival) of beacon RF signals measured locally at a sensor to detect range differences from the sensor to three beacon nodes. 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 location measurement in wireless sensor networks.
