Identifying Jammers in Wireless Sensor Network with an Approach to Defend Reactive Jammer
Apurva A. Bodkhe, Archana R. Raut · 2014
The jamming attack is one of the major security issues where a jammer node interferes with the signal of neighboring sensor nodes and thus disrupts the message delivery of its neighboring nodes. In wireless sensor network which is having a broadcast nature as well as limited resources such as battery power, memory, computational capabilities these jammers can create mass destruction to legitimate sensor communication. Reactive jamming attack is a light weight attack performed by the adversary but they are easy to launch and difficult to identify. Hence in this paper various techniques to identify the jamming attack has been discussed moreover the emphasis is laid on detecting the reactive jammers also a more efficient method has been proposed to identify and defend the reactive jammers in wireless sensor network using the sensing trigger nodes.
