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.
