Using a Two-Timer Scheme to Detect Selfish Nodes in Mobile Ad-Hoc Networks
Source: Washington State University
The cooperation of wireless nodes in ad hoc networks is crucial to ensure the proper working of the whole network due to the absence of infrastructure. Misbehaving nodes can dramatically decrease the performance of ad hoc network. Detecting and isolating the misbehaving nodes can not only make sure the participating nodes forward and route packets correctly, but also discourage the individual nodes from gaining advantages by not providing services to other nodes. This paper proposes a novel hardware assisted scheme which can detect one kind of misbehavior: Selfish nodes.
