Mitigating Selective Forwarding Attacks with a Channel-Aware Approach in WMNs Mitigating Selective.doc (Size: 27 KB / Downloads: 35) Abstract: Denial of service (DoS) attack in wireless mesh networks (WMNs) known as selective forwarding attack (a.k.a gray hole attacks). With such an attack, a misbehaving mesh router just forwards a subset of the packets it receives but drops the others. we consider a more practical and challenging scenario that packet dropping may be due to an attack, or normal loss events such as medium access collision or bad channel quality. Specifically, we develop a channel aware detection (CAD) algorithm that can effectively identify the selective forwarding misbehavior from the normal channel losses. The CAD algorithm is based on two strategies, channel estimation and traffic monitoring. If the monitored loss rate at certain hops exceeds the estimated normal loss rate, those nodes involved will be identified as attackers. Moreover, we carry out analytical studies to determine the optimal detection thresholds that minimize the summation of false alarm and missed detection probabilities. Existing System: 1. Only attack is detection 2. Packet Loss is not found Proposed System: 1. Selective forwarding attack / gray hole attack 2. Channel aware detection (CAD) algorithm 3. False Alarm. |
