Sensor nodes, when deployed to form Wireless sensor network operating under control of central authority i.e. Base station are capable of exhibiting interesting applications due to their ability to be deployed ubiquitously in hostile & pervasive environments. But due to same reason security is becoming a major concern for these networks. Wireless sensor networks are vulnerable against various types of external and internal attacks being limited by computation resources, smaller memory capacity,

This survey paper is an attempt to analyze threats to Wireless sensor networks and to report various research efforts in studying variety of routing attacks which target the network layer. Particularly devastating attack is Wormhole attack-a Denial of Service attack, where attackers create a low-latency link between two points in the network. With focus on survey of existing methods of detecting Wormhole attacks, researchers are in process to identify and demarcate the key research challenges for detection of Wormhole attacks in network layer.
