A Survey on variants of DoS attacks: Issues and defense mechanisms

Abstract

Wireless-based networks encompass assisted human life in distinct domains like Agriculture, health, infrastructure, climate, transportation and defense. In particular, the wireless sensor networks have been addressed in this article. Though it has many advancements, providing secure data transmission needs a major focus on these platforms. The disruptions or interference is one of the vulnerable security problems in Wireless Sensor Networks. Inside the network, an intruder can encroach and interrupt the whole transmission process. The involvement of an intruder in the device must be remembered in the network. WSN encompasses a wide geographical region and focus on rectification of issues in protocols for routing, interoperability, connectivity, and defense plays a major role. Hence, this article addresses about routing protocols of WSN, applications, recent network security issues and their variants of defense mechanisms. The conclusion depicts the classification of network security issues, requirements, and descriptive defense mechanisms for secure data transmission.
