A Survey on Different Methods for Secure Measure against Wormhole Attack in Wireless Sensor Networks

Abstract

Wireless sensor networks (WSN) consists of a limited set of sensor devices that are regionally distributed in a particular indoor or external environment (generally predetermined). Generally, sensors are utilized for the environmental sensing and transfer the information to the base station. Wireless sensor networks are susceptible to attack or danger due to different kinds of extrinsic and internal attacks that are being restricted by computational resources, reduced memory capacity, low battery life, processing power & deficit of tamper resilient packaging. Security is emerging to be a primary challenge for these networks. This survey paper tries analyzing the threats posed on Wireless sensor networks and different routing attacks targeting the network layer. Especially, a highly dangerous attack is Wormhole attack and when the worm hole is set, adversarial nodes can exploit it to launch a Denial of Service attack, and it is an attack with the motive of shutting down a machine or network, so that it becomes unavailable to its respective users, where the attackers form a low-latency link between two points in the network. Highlighting the survey of previous techniques used for the detection of Wormhole attacks, researchers are endeavoring to find and distinguish the primary research concerns for Wormhole attacks detection in network layer.
