Detection and Prevention Analysis of Wormhole Attack in Wireless Sensor Network

摘要

Wireless sensor network (WSN) is a collection of various sensor nodes. These sensor nodes sense data from the surrounding and send it to its destination following a proper route. A sensor network has various applications to monitor physical phenomenon in military, agriculture and medical applications where it can be used to make human life better in many ways. There are many issues in WSN like security, energy efficiency and QoS etc. which needs attention of today's research. There are several security attacks which affect the process of data dissemination. These security attacks spawn at various layers of Internet model which hampers the security of the network. In this paper, a comparative study of some detection and prevention methods of wormhole attack is presented. The various wormhole attack models and different modes of wormhole attack are also discussed in the paper.
