Detecting SF attacks in WSNs using CRS-A

In this system, we have proposed a channel-aware reputation system with adaptive detection threshold (CRS-A) to detect selective forwarding attacks in WSNs. To accurately distinguish selective forwarding attacks from the normal packet loss, CRSA evaluates the forwarding behaviors by the deviation between the estimated normal packet loss and monitored packet loss. To improve the detection accuracy of CRS-A, we have further derived the optimal evaluation threshold of CRS-A in a probabilistic ...
