A Review on Detecting and Isolating Sinkhole Attack in Wireless Sensor Networks

Wireless Sensor Network is a diverse system combining of small sensors with general purpose computing elements. Although various routing protocols have been proposed for Wireless Sensor Network, most of which do not take security into account seriously. Routing attacks can have ruining effects on Wireless Sensor Network and present a major challenge when designing powerful security mechanisms. Among them Sinkhole attack is the most destroy routing attack for these networks. It may cause the opponent to draw all or most of the data flow captured at the base station. The main aim of this paper is to study the various techniques and methods to detect and isolate the sinkhole attack in the wireless sensor networks and to compare these techniques. This paper also focuses on exploring and analyzing the existing solutions which used to detect and isolate sinkhole attack in wireless sensor network.
