Abstract
Technological advances are leveraging the widespread deployment of
mobile ad hoc networks. An interesting characteristic of ad hoc
networks is their self-organisation and their dependence of the
behaviour of individual nodes. Until recently, most research on ad hoc
networks has assumed that all nodes were cooperative. This assumption
is no longer valid in open (spontaneous) networks formed by
individuals with diverse goals and interests. In such environment, the
presence of selfish nodes may degrade significantly the performance of
the ad hoc network. In open mobile networks, users may become selfish
to defend their devices from the unfair load distribution presented by
many protocols, designed to optimise other criteria, such as the
number of hops in the message path.
This paper summarises research results addressing the problem of
unfairness in open mobile ad hoc networks from a two-side perspective:
the detection and punishment of selfish users and the definition of a
more fair network environment that attempts to leverage the load among
the participants to prevent selfish behaviour.
