Security Analysis of Routing Protocols for Wireless Sensor Networks

The demand for security is increasing day by day because of the awareness, technology and the increased applications of wireless networks, so there is a need to secure routing protocols which traverses across networks and contains user data. However, Wireless Sensor Networks (WSN) are vulnerable to various kinds of attacks and existing security mechanisms are not robust enough in the deployment of WSN. Lot of research has been done to incorporate improvisation in the existing routing algorithms with the objective of overcoming the impact of security attacks on WSN. This article highlights the work of eminent researchers who have given their contributions to improve the performance under the potential occurrence of Sinkhole, Grayhole, Blackhole, Wormhole and Selective forwarding attacks. This paper discusses on some of the improvements in the Routing protocols in Wireless Sensor networks or means of overcoming impact of security attacks on the Wireless sensor networks. This paper focuses on attacks like Sinkhole, Selective Forwarding, Grayhole, Wormhole and Blackhole. Related works on these attacks have also been discussed.
