Abstract
Wireless sensor network (WSN) is a network of sensors which are deployed in a surrounding to sense any physical phenomenon. These nodes can be deployed randomly or manually. Usually, randomized deployment is done in hard to reach territories and manual deployment is done in easy to reach areas. This emerging technology has several applications however, it also has several issues viz., power efficiency, scalability, responsiveness, reliability and security etc. Wormhole attack is one of such issues related to network security. This attack is done at network layer. There are various modes of this attack. Among these modes, wormhole attack based on high transmission power is focused in this paper. Here, we proposed a scheme for detection of this type of wormhole attack by using Received Signal Strength Indicator (RSSI) and the results of simulation are shown with various performance metrics.
