Denial of Service Attacks and Their Countermeasures in WSN

Wireless sensor network consists of tiny miniaturized motes which gather information about their vicinity and collaborate with each other through wireless link. These motes are mostly deployed in a harsh environment and left unattended for the duration of their lifetime. Hostility of the environment and physical intervention possess various threats to these energy-thirsty sensor motes which results in severe catastrophic affects. In this paper, the authors have provided a brief overview of denial of service attacks at various layers and proposed countermeasures available in literature and their proposed solutions in wireless sensor network. In Denial of Service attack, a sensor node is deprived of resources in one way or another. Also, security is classified into four major classes in this paper.
