Paper Details

Several distributed protocols have been proposed to detect node clone attack in Wireless sensor. On the otherhand, they need too strong assumptions to be realistic for large-scale, randomly deployed sensor networks. In thismanuscript, we suggest two new node clone detection protocols. The first one is distributed hash table (DHT). DHT is one ofthe most powerful node clone detection system with fully decentralized, key-based caching and checking system. The protocolperformance on efficient storage consumption and high security level is theoretically deducted through a probability model,and the resulting equations, with necessary adjustments for real application, are supported by the simulations. Although theDHT-based protocol incurs similar communication cost as previous approaches, it may be considered a little high for somescenarios. To address this concern, our second distributed detection protocol, named randomly directed exploration,presents good communication performance for dense sensor networks, by a probabilistic directed forwarding techniquealong with random initial direction and border determination. The simulation results uphold the protocol design and show itsefficiency on communication overhead and satisfactory detection probability.
