    (IEEE, 2015-08-24) Karunaratne, K. H. M. C. D; Karunaratne, K. H. M. C. T; Peiris, M. H. D; Peiris, P. A. S; Rupasinghe, L; Senarathna, A. N
    Trust is an indispensable component in mobile ad-hoc networks since the devices involved in the network can be complete strangers to each other. In a situation where there is a need of a suddenly build network and exchange of data, a trust establishment mechanism plays a vital role. In developing a trust implementing system, the traditional methods such as cryptography and centralized certificate based solutions are ill-suited due to the lack of processing power and energy in mobile devices. In this paper, we propose a trust mechanism based on the predictive theories of probability, Markov Chains and Hidden Markov Models.
