The Jamming-style Denial of Service (J-DoS) attacks are significant causes of malfunctioning of Wireless Sensor Networks (WSNs). The nodes of WSNs are prone to external disturbances especially when they are used in hostile environments. The attackers mainly operate in the wireless communication medium by following a couple of diverse scenarios. In this paper, we have developed two detection mechanisms used for J-DoS attacks in order to differentiate the legitimate and adversary scenarios. The detection mechanisms designed utilize some network parameters and additional packets to separate and classify normal conditions and adversary ones. Having detected the type of the attacker, appropriate counter measures can be applied.
Two jamming detection algorithms are proposed to detect the presence of different jamming attacks in the sensor network REF .
