Prevention of Wormhole Attack in Wireless Sensor Network

Abstract

Ubiquitous and pervasive applications, where the Wireless Sensor Networks are typically deployed, lead to the susceptibility to many kinds of security attacks. Sensors used for real time response capability also make it difficult to devise the resource intensive security protocols because of their limited battery, power, memory and processing capabilities. One of potent form of Denial of Service attacks is Wormhole attack that affects on the network layer. In this paper, the techniques dealing with wormhole attack are investigated and an approach for wormhole prevention is proposed. Our approach is based on the analysis of the two-hop neighbors forwarding Route Reply packet. To check the validity of the sender, a unique key between the individual sensor node and the base station is required to be generated by suitable scheme.Comment: 14 pages; International Journal of Network Security & Its Applications Year: 2011 Vol: 3 Issue:

Detection of Wormhole Attack and Mintroute Protocol

“…They can also spy on the packets going through and use the large amount of collected informat ion to break any network security. The wormho le attack [3] will also affect connectivity-based localization algorith ms and protocols based on localization, like geographic routing, will find many inconsistencies resulting in further network d isruption.…”
