Um novo modelo para confiança em redes ad hoc

Pedro B. VellosoRafael P. LauferOtto Carlos M. B. DuarteGuy Pujolle

This paper proposes a new approach to assign trust in ad hoc networks. Our system is inspired on the human concept of trust. The trust level considers the recommendation of trustworthy neighbors and their own experience. For the recommendation computation, we take into account not only the trust level, but also its accuracy and the relationship maturity. We also propose the Recommendation Exchange Protocol (REP), which aims at minimizing the number of exchanged messages. We analyze through simulations the main characteristics of the proposed model. The results show its eficacy and how parameters can be tuned to different network conditions.
