Access Aware Routing Protocol (AARP) Towards Trust Management for Mobile Ad Hoc Networks

In this paper, Access Aware Routing Protocol (AARP) towards Trust Management problem for Mobile Ad hoc Network (MANET) is proposed. In MANET, nodes periodically move over the terrain space with transmission range. In this research work a scheme to handle trust establishment and aggregation issues are proposed. Unlike trust management in previous schemes, trust management in MANET involves neighbor trust relationship along with location and time factors. Trust relations as a trust graph is modelled in order to enhance accuracy and efficiency of trust establishment among mobile nodes. The proposed mechanism is a decentralized and self-configurable trust aggregation scheme. To evaluate the performance, the proposed scheme is implemented in NS2. Packet delivery ratio, delay and overhead are the performance metrics chosen for the comparison with the existing scheme. Simulation results proved that the proposed scheme outperforms in terms of the chosen performance metrics.
