Usman, Aminu Bello, Gutierrez, Jairo.  2016.  A Reliability-Based Trust Model for Efficient Collaborative Routing in Wireless Networks. Proceedings of the 11th International Conference on Queueing Theory and Network Applications. :15:1–15:7.

Different wireless Peer-to-Peer (P2P) routing protocols rely on cooperative protocols of interaction among peers, yet, most of the surveyed provide little detail on how the peers can take into consideration the peers' reliability for improving routing efficiency in collaborative networks. Previous research has shown that in most of the trust and reputation evaluation schemes, the peers' rating behaviour can be improved to include the peers' attributes for understanding peers' reliability. This paper proposes a reliability based trust model for dynamic trust evaluation between the peers in P2P networks for collaborative routing. Since the peers' routing attributes vary dynamically, our proposed model must also accommodate the dynamic changes of peers' attributes and behaviour. We introduce peers' buffers as a scaling factor for peers' trust evaluation in the trust and reputation routing protocols. The comparison between reliability and non-reliability based trust models using simulation shows the improved performance of our proposed model in terms of delivery ratio and average message latency.
