Security Analysis of Wormhole Attack in WSN

Abstract

With the tremendous growth of mobile devices, the deployment of wireless sensor networks in the
unfavorable environment makes it very popular for research field. Wireless sensor networks (WSN) is widely used in
various fields, like Military, Health (Scanning), Space Exploration, Vehicular Movement, Mechanical stress levels on
attached objects, Environment monitoring, Weather forecasting, Traffic control, Natural disaster prevention etc. WSN is
made of by significant number of nodes deployed in an unfavorable area in which not all nodes are directly connected.
The data exchange carried by multihop communications. Routing protocols are responsible for discovering and
maintaining the routes in the network. Now a day, Security is prime concern for wireless sensor network. Wireless sensor
networks are very weak and susceptible to many types of security attacks, like Sybil attack, Blackhole attack, Flooding
attack, Wormhole attack etc. The wormhole attack creates serious issues in WSN, such as routing error, a reduction in
sensor lifetime and broken network topology. Several wormhole detection approaches have been proposed, but most of
them need special hardware devices and consume a lot of system resources. The main aim for this research to detect
wormhole attack in wireless sensor Network (WSN) and at the same time perform rescue task to defend against attack.
All the simulation will be performed in NS2.
