Wireless sensor networks (WSNs) can be used in many applications. Object tracking is one of the most important applications. There are many researches about tracking individual object but few researches on tracking continuous object. Continuous object affects a large number of nodes so needs more communication and cooperation to track it comparing with individual object. In this paper we propose an...
In order to resist the attack from malicious Cognitive Radio (CR) users, a reputation-based collaborative spectrum sensing model is proposed in this paper. In this model, each collaborative CR user has a reputation degree, which is set by the central controller and used to weight the sensing result from corresponding CR user in the fusion process at the central controller. We analyze and evaluate...
