Fuzzy logic based reputation system for mobile Ad Hoc networks

Mobile ad hoc networks (MANET) consist of some mobile nodes, but do not have the requirement of infrastructure or centralized management. As a result, there may have a lot of critical issues occurred in mobile ad hoc networks, such as the security of data transmission, routing, and so on. The misbehavior of nodes which are due to selfish or malicious may lead to the losing of packets, rejecting of services, etc. In this paper, a new scheme based on reputation, bandwidth and hop count is proposed to solve these problems. This scheme employs the fuzzy logic to perform the routing path decision in order to choose the best and feasible routing path. Finally, the SMPL, a simulation too], is utilized to estimate the efficiency of the proposed scheme. From the results, the proposed scheme is superior to other existing schemes.
