ECAODV: Enhanced classified ad-hoc on demand distance vector routing protocol

Abstract

Mobile Ad-hoc Network (MANET) is independent, self-organizing and infrastructure less Ad-hoc network. Ad-hoc based routing protocols are being used for route discovery and route establishment. Among these Ad-hoc based protocols; Ad-hoc on Demand Distance Vector (AODV) is one of the reactive Ad-hoc routing protocols designed with inherited best features of DSR and DSDV. Using AODV a number of techniques have been presented for maintaining secure communication between communicating parties using symmetric and asymmetric cryptography, which have significant limitation of key management and high cost. In this paper we have proposed Enhanced Classified Ad-hoc on Demand Distance Vector protocol with a unique key management infrastructure for building cost effective and establishing secure links between nodes in MANET. Our proposed technique establishes session key between nodes in an authenticated way using signcryption and symmetric cryptographic technique Blowfish for secure data communication. The proposed protocol Enhanced Classified-AODV (ECAODV) provides all security features with tremendous low computation and communication cost. This work will greatly contribute to the security of AODV for secure MANET communication over other preceding proposed security techniques for AODV. © 2012 Springer-Verlag.
