摘要：Node replication detection is a challenging problem. Though the defending against node replication attacks demands immediate attention as compared to the extensive exploration on the defense against node replication attacks in static networks, only a few solutions in mobile networks have been presented. Additionally, whereas most of the presented schemes in static networks exist on the witnessfinding strategy that cannot be applied to mobile networks, the velocity-exceeding strategy used in existing schemes in mobile networks incurs efficiency and security problems. Thus, based on our devised challenge-and-response and encounter-number approaches, required algorithms are proposed to resist node replication attacks in mobile sensor networks. The advantages of our proposed algorithms include 1) localized detection; 2) efficiency and effectiveness; 3) network-wide synchronization avoidance; and 4) networkwide revocation avoidance. The Performance comparisons with existing methods are provided to demonstrate the efficiency of our proposed algorithms. Prototype implementation on TelosB mote demonstrates the practicality of our proposed methods
