A WORMHOLE ATTACK SURVEY IN WIRLESS NETWORKS

Sara Ali, Dr S Krishna Mohan

Abstract :

Wireless networks have gained tremendous importance in the last decade. The users desire to use wireless connectivity regardless of their geographic location. This has led to increase in the treats face by the network. The nodes operating in a mobile network act as both client and intermediate router, as a result the resulting multi–hop communication is not secure. Wormhole attack is one of the most serious routing threats launched at the network layer. This attack can be implemented by creating a tunnel at two ends of the network by one or more malicious nodes which disrupts the routing paths in a wireless network. In this paper we try to conduct a detailed study on the wormhole attacks by classifying the attacks and considering different prevention and detection mechanism for the same
