Using a Cache Scheme to Detect Misbehaving Nodes in Mobile Ad-Hoc Networks

-- This paper presents a hardware based cache scheme to detect misbehaving nodes in mobile ad hoc network. In this scheme, the hardware monitors the activities of the upper-layer software and reports the misbehavior of the software to other mobile nodes in the network. The hardware cache stores the identity information of recently received packets. The detection mechanism uses the cache to detect packet dropping and packet misrouting. The simulation results show that the cache scheme can detect nearly 100% misbehaving nodes with nearly 0% false positive in the packet dropping scenario. In the packet misrouting scenario, the detection has nearly 0% false positive and more than 90% detection rate. The detection result could be used by other nodes to protect the network.
