Mobile Ad Hoc Network Security for Reactive Routing Protocol with Node Reputation Scheme

A. Suresh and Dr. K. Duraiswamy


The mobile node’s reputation in the Mobile Ad hoc Network (MANET) identifies its trust worthiness for secured multiple data communication. Unknown nature of the node’s communication status for initial period has great impact in the effective data transfer as MANET is self-organized and distributed. Problem statement: The functional operation of the mobile network relies on the trusty cooperation between the nodes. The major factor in securing the MANET is based on the quantification of node’s reputation and trustworthiness. The previous literatures provided uncertainty model to reflect a node’s confidence in sufficiency of its past experience and effect of collecting trust information from the unknown node status. With node mobility characteristic, it reduces unknown nature and speed up trust convergence. Approach: Mobility-assisted uncertainty reduction schemes comprised of, proactive schemes, that achieve trust convergence and reactive schemes provide node authentication and their reputation. They provide an acceptable trade-off between delay and uncertainty. The mobility based node reputation scheme presented in this study, identifies and monitor the node’s trustworthiness in sharing the information within the ad hoc network. Mobile nodes information uncertainty is handled with the mobility characteristics and its reputation is evaluated to trust or discard the node’s communication. Results: Simulations are carried out to evaluate the performance of mobility based node reputation scheme by measuring the nodes consistency behavior, neighboring communication rate and path diversity. Conclusion: The average node’s neighboring communication rate is high for the proposed mobility based reputation scheme compared to the reactive routing protocols.
