Analysis of DoS attack in various layers of Wireless Sensor Network

Abstract

A wireless sensor networks (WSN) is a recent advancement of technology of computer networks and electronics. They have a wide variety of applications ranging from data gathering to data transmission through wireless media. Along with these applications, WSN also has some weakness due to which its sensor nodes are vulnerable to most of the security threats. Denial-of-Service (DoS) attack is one of the most popular attack. This attack affects different layers of WSN and each layer has different type of DoS attack. Tackling this attack requires knowledge of all these types of DoS attacks. In this paper, WSN security requirements are studied. DoS attack on various layers of WSN and most common techniques to avoid these attacks are also analysed.
