Detection of Wormhole Attack in Wireless Sensor Networks

Although Secure routing is the demand of the hour in the application of wireless sensor networks (WSN), secure routing is a challenge in itself due to the inherently limited capacities of sensor nodes. Routing attacks are a major challenge in the process of designing of effective and robust security mechanisms for WSNs. This main focus of this paper is on wormhole routing attack. The measures which have been proposed till now to counter the routing attacks suffer from flaws that essentially prove the fact that they are not good enough for use in large-scale WSN deployments. We need light weight and hard-bearing security mechanisms due to inherent limitations found in WSNs. In this paper, we discuss a wormhole detection method: WGDD (wormhole geographic distributed detection).
