Wireless sensor networks are usually deployed to monitor environmental fields. In this work, we take a different viewpoint by dual-using the wireless sensor networks beyond their original purpose and exploit the general spatial information fields associated with wireless networks to assist position verification and refine conventional localization results. We developed the Flex - EP algorithm. And further our experimental evaluation results provide strong evidence that our approach can achieve the similar performance as traditional localization algorithms, without requiring the deployment of a localization infrastructure.
