Abstract- Wireless Sensor Network (WSN) [1] is a network which has several small sensor devices responsible for communicating and sensing data wirelessly with each other. WSN have a various field of applications such as military, healthcare monitoring, traffic monitoring, industrial monitoring, undersea monitoring, agriculture monitoring etc. These networks are implemented in unprotected environments, thus vulnerable to various kind of security threats results in breaching network security[2]. Blackhole attack is one of such kind of attack. Different techniques have been studied which detects and prevents blackhole attack. Various advantages and disadvantages of different techniques are also discussed which helps in finding best approach for blackhole attack. This paper focuses on analysis of various detection and prevention methods of blackhole attack in WSN.

Keywords WSN, Malicious node, Blackhole attack.
