Selfishness detection in mobile ad hoc networks: How dissemination of indirect information turns into a strategic issue

For a mobile ad hoc network, the tradeoff between a selfish node´s power expense and ill reputation is discussed.

Fake recommendations, however, such as false appraisals or false accusations, necessitate an additional revocation scheme.
