Game theoretic modelling of WSN jamming attack and detection mechanism

Nowadays wireless sensor networks (WSNs) are going to be more prone to different security threats and attacks. The different attack reduces the capability of WSN, to work for long time. It largely effects on resource consumption of network and increases the energy consumption, delay, and reduces the throughput. Among all the different WSN security attacks, jamming attack affects largely on performance of WSN. Jamming attack jams the network by making resources busy for long time and increases the crunch of resources, which leads to reduction in performance. The aim of the paper is to form the game theoretic model of the jamming attack, to understand the different strategies of jamming game when jammer behaves in different ways. The paper also proposes the game theory based detection mechanism for all kind of jamming attacks. The proposed detection mechanism shows better energy consumption, throughput, and delay in different realistic situations of network (e.g. varying- amount of traffic and number of malicious nodes) as compared with existing optimal strategy solution.
