Abstract
A novel node misbehavior detection system called GIFTED is proposed for a multihop wireless ad hoc network (WAHN) whose nodes may selfishly refuse to forward transit packets. The system guesses the nodes’ intrinsic forwarding trustworthiness (IFT) by analyzing end-to-end path performance rather than utilizing unreliable and incentive incompatible low-layer mechanisms. It can work with occasional IFT jumps, directional antennae, multichannel transmission, end-to-end encrypted packets, any single-path source routing protocol, and any number of selfish nodes; this makes it a valuable alternative to existing misbehavior detection schemes. GIFTED relies on approximate decomposition of a path equation system arising from successive performance reports from source nodes. The ability to near-perfectly guess IFT in the presence of various perturbations is demonstrated through Monte Carlo and time-true simulations, and compared with an existing weighted path trust scheme.
