The self-configuring ability of nodes in Mobile Adhoc Network (MANETs) made it popular among critical applications like military use or natural emergency recovery. Most of the proposed protocols assume that all nodes in the network are cooperative, and do not address any security issue. To adjust such trend, it is vital to address its potential security issues. The main objective of this paper is to define the path for security and to further improve delay, energy, throughput, routing overhead, packet delivery ratio and at the same time to create energy enhanced way with excellent security. In this paper, performance analysis of hybrid cryptography with reactive protocol Elliptic Curve Cryptography - Ad hoc On- Demand Distance Vector Routing (ECC-AODV) designed for MANET. In this design there is a two key encryption technique based on elliptic curve based theory that can be used to create faster, smaller, and more energetic and efficient cryptography. Network Simulator (NS2) is used to implement and test the proposed system.
Due to the mobility of the nodes, the topology often changes, causing the link to fail. Lack of infrastructure support and limited resources are the main causes of dishonest and uncooperative nodes, and in finding a route to a destination and opening new routes. As a result of the frequent discovery, there is large network congestion that occurs. Multipath routing protocols are designed to find multiple routes to a target, and switch to a backup secondary path if the primary route is violated to avoid this. These protocols also provide better routing performance and security. This paper examines two ondemand MANET protocols, a Trusted Secure Dynamic Source Routing (TS-DSR) and a Modified Trusted Secure Dynamic Source Routing (MTS-DSR), as well as a mechanism for gateway discovery on demand.
