Enhanced AODV Authentication Mechanism in MANET

MANET networks are vulnerable to many security attacks ranging from passive eavesdropping to active impersonation, message replay or message distortion. To mitigate some of the above issues, this paper will introduce a new authentication mechanism between certain nodes that form a MANET Network. The protocol studied is AODV (Ad-hoc On-Demand Distance Vector Routing) because of its popularity and lack of many security features. The paper will review the latest research papers on this field and will describe our proposed solution that can mitigate certain security vulnerabilities. Some performance aspects will be also taken into account because any new security enhancements should not have a major impact on the overall network performance.
