A Secure Hashed Variable Bit Rate Source Routing Protocol and Mitigation of Wormhole Attack for Manets
V. Rajamani · 2014
2 Abstract: In Mobile ad hoc networks, security is one among the many challenges to be taken care of Passive attacks and active attacks are the common types of attacks in Mobile ad hoc networks of which active attacks are more harmful than passive attacks, as there is no central coordination in MANETs. Examples of active attacks are: Worm hole attack, Black hole attack and Distributed Denial of Service (DDoS) attack and etc., In this paper, Hashed VBSR is taken into consideration. In Hashed VBSR clusters are formed based on the distance from all the nodes to a central node. Then the one time keys are managed among the user inside the cluster. Gateway members are playing the main role in group formation and preventing these attacks. In this Secure Hashed VBSR proposed work, the wormhole attack is discussed and security is analyzed.
