Abstract
In this paper, we propose an efficient and practical localization technique especially designed for mobile sensor networks. It uses a single mobile anchor travelling with a predefined trajectory while periodically broadcasts its current location coordinates to the nearby sensors. Using previous location information, the node predicts its speed and direction. The evaluation of our solution shows that our technique takes benefit from both, prediction and anchor trajectory, in a more effective manner than previous solutions. The simulation results show that our algorithm outperforms conventional Monte Carlo localization schemes and its variant MCB.
