Many proposed routing protocols for ad hoc networks operate in an ad hoc fashion, as on demand routing protocols often have low overhead and faster reaction time than other types of routing based on periodic protocols. Dynamic nature of ad-hoc networks leads to challenges in securing the network. Due to the vulnerable nature of ad-hoc networks there are many security threats. One of the solutions 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 interfere this protocol and disturb the network by dropping packets. However varieties of attacks targeting routing protocols have been identified.
