Activity Modelling and Countermeasures on Jamming Attack

In last few decades, there has been a wide demand of wireless sensor networks (WSNs) in extensive mission critical applications such as monitoring, industrial control, military, health and many more. The larger demand of WSN in mission critical applications makes it more prone towards malicious users who are trying to invade. These security assaults worsen the performance of WSN in large extent in terms of energy consumption, throughput, and delay. Therefore, it is necessary to save the WSN from these attacks. The major aim of researchers working on WSN security is to enhance the performance of WSN in presence of these attacks. The major concentration of this paper is to model the behaviour of different kinds of jamming attacks using activity modelling and to find countermeasure against it. Jamming attack is the one of the ruinous invasion which blocks the channel by introducing larger amount of noise packets in a network. The activity modelling of jamming attack gives the perfect understanding of its accomplishment on WSN and it is useful to develop the security countermeasure against the attack. This paper also gives the survey of different countermeasures of WSN and proposes the new countermeasure on jamming attack. The paper suggests the Threshold based Jamming Countermeasure (TJC) on reactive jamming attack which detects the jamming in network and save the network against reactive jamming attack. The implementation of proposed mechanism in different realistic conditions shows that TJC saves the network in case of reactive Journal of Cyber Security and Mobility, Vol. 2, 1–27. c © 2013 River Publishers.
