Study of Various Wormhole Attack Detection Techniques in Mobile Ad hoc Network

Security is a service for wireless ad-hoc networks communications. The success of mobile ad hoc network will depend on people's confidence in its security. The characteristics of MANET are both challenges and opportunities in achieving security models, such as confidentiality, integrity, authentication, availability, non-repudiation and access control. We provide a survey of wormhole attack types and various detection techniques in MANET and at last Qualitative Comparison of Wormhole Detection Methods. The countermeasures are features or functions that reduce or eliminate vulnerabilities and attacks.
