Paper Details

we propose a channel-aware reputation system with adaptive detection threshold (crs-a) to detect selectiveforwarding attacks in wsns. The crs-a evaluates the data forwarding behaviors of sensor nodes, according to thedeviation of the monitored packet loss and the estimated normal loss. To optimize the detection accuracy of crs-a, wetheoretically derive the optimal threshold for forwarding evaluation, which is adaptive to the time varied channelcondition and the estimated attack probabilities of compromised nodes. Furthermore, an attack-tolerant data forwardingscheme is developed to collaborate with crs-a for stimulating the forwarding cooperation of compromised nodes andimproving the data delivery ratio of the network. Extensive simulation results demonstrate that crs-a can accuratelydetect selective forwarding attacks and identify the compromised sensor nodes, while the attack-tolerant data forwardingscheme can significantly improve the data delivery ratio of the network.we will extend our investigation into wireless adhoc network with mobile sensor nodes, where the detection of selective forwarding attacks becomes more challenging,since the normal packet loss rate is more fluctuant and difficult to estimate due to the mobility of sensor nodes.
