Approaches and Measures to Detect Wormhole Attack in Wireless Sensor Networks: A Survey

Wireless sensor networks (WSNs) contain a collection of sensor nodes. These nodes are linked with one another and have low computational power. Wireless sensor network is used for sending messages, data, and other important information over a wireless link for military purpose, environmental monitoring, Health checkups for patents, habitat monitoring, target tracking, and disaster management. Security is most important concept in WSN while sending such important message over wireless link. This permit attacker to penetrate the network and carried out various possible attacks with the purpose of stealing or editing actual data/information. In this paper, discussions are made on different techniques available to avoid and detect wormhole attack.
