Abstract

Jamming attack is quite serious threat for Mobile networks that collapses all necessary communication infrastructure. Since mobile nodes in Mobile Ad Hoc Networks (MANET) communicate in a multi-hop mode, there is always a possibility for an intruder to launch a jamming attack in order to intercept communication among communication nodes. In this study, a network simulation has been carried out in order to explore and evaluate the possible impacts of jamming attack on MACAW protocol. Ad-hoc network modelling is used to provide communication infrastructure among mobile nodes in order to modelling the simulation scenarios. In simulation model, these nodes have used AODV routing protocol which is designed for MANET while second scenario contains simulated MACAW node models for comparison. On the other hand, this paper is the first study that addresses performance evaluation of MACAW protocol under a constant Jamming Attack. The performance of MACAW protocol is simulated through OPNET Modeler 14.5 software.

Highlights

Wireless networks take important place in the world of communication
Multiple Access with Collision Avoidance for Wireless (MACAW) protocol has been exposed to a constant Jamming Attack which results high collision occurrence rate in the network
It is seen in the simulation results that, a Jamming Attack in a mobile ad-hoc network leads to loss of performance of MACAW

Summary

Introduction

Wireless networks take important place in the world of communication. Today a great number of people such as businessmen, managers, students and employees can access to the internet or to the corporate networks through wireless connections. Wireless technologies expand the limits of communication area, they are exposed to some problems due to their nature. These problems violate quality of wireless communication.
