Nodal cooperation equilibrium analysis in multihop wireless ad hoc networks with a reputation system

Abstract

Motivated by the concerns of cooperation security, this work examines selected principles of state-of-the-art reputation systems for multihop adhoc networks and their impact upon optimal strategies for rational nodes. An analytic framework is proposed and used for identification of effective cooperation-enforcement schemes. It is pointed out that an optimum rather than high reputation can be expected to be sought by rational nodes.
