Abstract:
Estimation of trust in ad-hoc networks is an inevitable
basis for hybrid networks to inter-operate. The
contributions in this paper provide a framework for
estimating the trust between nodes in an ad hoc network
based on quality of service parameters. Probabilities of
transit time variation, deleted, multiplied and inserted
packets, processing delays are used to estimate and
update trust. Functions which facilitate this are provided
and evaluated. It has been shown that only two end nodes
need to be involved and thereby achieve reduced
overhead. The framework proposed is applicable and
useful to estimate trust in covert unobservable and
anonymous communications.
