Security mechanisms Analysis of Wireless Sensor Networks specific Routing attacks

Secure routing is a challenging task because ad-hoc and resource constrained nature of wireless sensor networks. In this paper, we discuss several specific routing attacks, such as wormhole attack, sinkhole attack, Sybil attack, false data insert attack etc. Some security mechanisms, which are used to defend against these attacks, are analyzed. This paper also points out the open research challenges in this field
