A survey on various detection techniques of sinkhole attacks in WSN

Wireless Sensor Network (WSN) is a network consists of many sensor nodes that are capable of sensing and communicating with in a shortest range. Security is one of the main issues in WSN due to its communication nature. The sensor nodes been prone to various attack such as sinkhole attack, wormhole attack, gray hole attack etc. Sinkhole attack is one of the attacks in WSN where the sinkhole node showcases itself having the shortest path to sink or destination node. Researchers proposed different methodologies to detect the sinkhole attack. In this paper, we have studied sinkhole attack and we have classified the sinkhole detection method by using various parameters. It also reviewed the threats and challenges in WSN through this attack.
