Security Attacks in Wireless Sensor Networks: A Survey

Wireless Sensor Network (WSN) is being emerged as a prevailing technology in future due to its wide range of applications in military and civilian domains. These networks are easily prone to security attacks, since once deployed these networks are unattended and unprotected. Some of the inherent features like limited battery and low memory make sensor networks infeasible to use conventional security solutions. There are lot of attacks on these networks which can be classified as routing attacks and data traffic attacks. Some of the data attacks in sensor nodes are wormhole, jamming, selective forwarding, sinkhole and Sybil attack. In this paper, we discussed about all these attacks and some of the mitigation schemes to defend these attacks.
