Abstract: Packet delivery of Ad hoc networks depends on collaboration among distributed entities. Different needs on the trust models of varieties of routing protocols were analyzed separately. The robust trust mechanisms(RTM) were proposed to meet the new demands of source routing protocols for trust models. A new scheme for gathering first hand trust information from non-neighbor nodes using acknowledgements was presented in paper. The RTM expands the OTMF by providing recommendation trust revision support, which is based on I3ayesian Decision-Making theory and minimum-loss principle and promotes accuracy of trust value. Simulations show that compared with the OTMF, the RTM is helpful to reduce the impact of some threats on trust management and has better convergence.
