Survey on Wormhole Attack Detection Techniques in Mobile Ad-hoc Network
Dipika Baid, Kriti Dugar, Pratima Sarkar · International Journal of Computer Applications · 2015
Mobile Ad-hoc Network (MANET) exposes itself to wide range of security attacks due to its broadcast nature and lack of central authority, wormhole attack is one of devastating attack that can easily be launched by attacker without the knowledge of the network of compromising any legitimate nodes or cryptographic mechanisms.Here a malicious node can drop, delay, tunneling or replay the packets depending nature of the attack.As malicious nodes in wormhole attack hide their original identity and they do not compromise any node so detection of this attack is difficult.In this paper several detection techniques of wormhole attack in a MANET are discussed that uses on demand AODV or DSR routing protocol.The result shows comparison between different wormhole attack detection techniques.
