Techniques for Identifying Denial of Service Attack in Wireless Sensor Network a Survey

Abstract: Wireless Sensor Networks is a type of computer network, which is commonly used for environmental monitoring and military observation. Wireless sensor networks are frequently affected by jamming attacks and broadcast attacks. Securing WSN is a challenging task. The prominent attack in WSN is Denial of Service (DoS) attack. DoS attack is caused by jamming single or group of nodes and there by disrupting the communication. This paper depicts the different types of DoS attacks. It also elaborates the techniques adopted by several researchers for Detecting DoS attacks.
