ABSTRACT

Dynamic nature of adhoc networks leads to challenges in securing the network. Due to vulnerable nature of adhoc networks there are many security threats. Much work is going on to provide security to the network. One of the solution to the problem is ARAN – Authenticated routing protocol which is a secure protocol and provides Integrity, Availability, Confidentiality, Authenticity, Non repudiation, Authorization & Anonymity but an authenticated selfish node can infer to this protocol performance and can disturb the network by dropping packets. This paper discusses reputation based schemes that can be applied to ARAN to detect selfish node and improve the performance.
