Title: Fuzzy Logic based Trust Management Framework for MANET
Authors: V. R. Ghorpade and Y. V. Joshi and R. R. Manthalkar
Abstract: In order to advance the goal of anywhere anytime computing, the exposure to the risky transactions in mobile ad hoc networks has to be reduced as much as possible. This requires an existence of a trust management framework that enables nodes to form, maintain and exchange trust opinions. These opinions can then be used to customize the way interactions take place. A trust management framework for mobile ad hoc network (MANET) must be fully decentralized, highly customizable and selfish. In this paper, a fuzzy logic based trust management framework to establish, evaluate and propagate trust in MANET has been presented. In the proposed framework, trust is established by directly monitoring the evidences and obtaining fuzzy logic based recommendations from the neighboring nodes. A membership function is devised to take trust decision in a more accurate manner. This approach is optimistic in the sense that it allows more and more number of nodes to participate in network operations with different grades of trustworthiness. Mathematical analysis and simulations show that the proposed trust management framework can significantly improve the number of motivated nodes in the network which ultimately improves the network performance.
