Abstract
Consider multi-path routing and forwarding scenarios in wireless ad hoc networks. Rational and Byzantine nodes both might deviate from the protocol. However, their intentions and behaviors are different. To extend our previous work on generalized second price (GSP) auction for stimulating rational nodes for cooperation, we propose FORBID mechanism in this work to cope with Byzantine behaviors. The core of the FORBID mechanism is a decentralized reputation system. Based on available evidence, each node relies on Bayesian inference to internally update its reputation beliefs that how reliable each other node is. Different from the passive overhearing techniques such as ''watchdog'', each source node under FORBID actively triggers detection process to collect evidence towards Byzantine behaviors. In addition, FORBID includes a flocking algorithm to allow careful dissemination of reputation information and thus shortens the misbehavior detection time. © 2011 IEEE.
