FUZZY-BASED ROUTING SCHEME IN MOBILE AD HOC NETWORKS

摘要

In mobile ad hoc networks, mobile nodes have to communicate to each other without any infrastructure or base station. Thus, a lot of critical routing decision factors should be taken into considerations, such as reputation, reliability, availability, security, and mobility. Specially, the misconduct nodes due to unreliability, malfunction, migration, or malice may result in the loss and delay of packets. This paper proposes a fuzzy-based routing scheme based on reputation, bandwidth, and distance to overcome the misconduct mobile nodes and to enhance the performance of throughput. The scheme utilizes the ad hoc on-demand distance vector, the exponential smoothing model, and the fuzzy multiple-criteria group decision-making method to perform the routing path decision. Finally, the simulation is used to illustrate the performance of proposed scheme and existing methods. From the simulation results, the proposed scheme has better throughput than other schemes.
