ASRMalNets: Acknowledgement Based Secure Routing Scheme for Malicious MANETs

Abstract

A m o b i l e ad hoc network is a wireless commu- nication network, where communicating nodes are not within direct transmission range of each other. Since the radio links between t h e nodes b r e a k frequently, routing is a key issue in MANETs. The wide distribution of nodes makes M A N E T s vulnerable to malicious attacks. Hence huge researches are going on in this area. Efficient routing always c o n f l i c t s with secure packet transmission. Both these issues are highly challenging in MANETs and should go by hand. The paper presents a technique to address this tradeoff. Malicious n od es interrupt t h e communication by dropping all the data packets. The paper is an Acknowledgment b a s e d Secure Routing Scheme in Malicious MANETs. According to this mechanism, the packet delivery is ensured even in the presence of malicious nodes. The main objective of this scheme is to achieve reliable data delivery in a malicious network. Performance of the proposed s y s t e m is compared with the existing routing algorithm AODV using Network Simulator.
