Detecting Sinkhole Attacks by Observing the Quality of Link in Wireless Sensor Networks

摘要

A sinkhole attack is one of the severe attacks in wireless sensor networks. This attack compromises nodes of a particular are, and diverts the traffic from the base station into the sinkhole. To determine a sinkhole, we first derive the quality of the link using forward and reverse transmission metrics and a stochastic model. We then use the sampling technique to confirm the quality of the link. The two methods along with root mean square formula detect the area concentrated by the malicious nodes. The proposed model for quality of link leads to determine the compromised nodes in the path and the sinkhole.
