Abstract
Mobile Ad hoc Network (MANET) is a self creating, self-configuring and self healing network that is formed automatically by a collection of mobile nodes without the help of a fixed infrastructure or centralized management. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Security has become a primary concern in order to provide protected communication in wireless as well as wired environment. In recent years mobile ad hoc networks (MANETs) have received tremendous attention because of their self-configuration and selfmaintenance capabilities. The various attacks which are likely to occur in MANET are blackhole attack, grayhole attack, replay attack, wormhole attack, rushing attack, and etc. In this research paper an attempt is made to find a solution for this challenge by implementing data integrity using hash chain mechanism on hop to hop basis and confidentiality using digital signatures on end to end basis. The light weight Elliptic curve cryptography (ECC) is used to generate the digital signatures. In this research paper an attempt is made to find a solution for this challenge by introducing a new routing protocol called Elliptic Curve Cryptography Enabled AODV (ECCEA) as an extension to the conventional Ad-hoc On-demand Distance Vector (AODV) routing protocol. The proposed routing protocol is simulated by using the discrete event network simulator NS-2 and performance evaluation is carried out by calculating the QOS parameters such as Packet Delivery Ratio, Average End-to-End Delay, Throughput, and Normalized Overhead.
