In mobile ad hoc networks, security is the main among the challenges to be considered. There are various types of attacks such as passive attacks and active attacks. Active attacks are more harmful than passive attacks. Examples of these attacks are: Worm hole attack, Black hole attack, Distributed Denial of Service (DDoS) attack, etc. In this paper, Secure VBOR is taken as the authors' base paper. In Secure VBOR, groups are formed based on the residual energy of the node. Then the keys are exchanged among the user inside the group. Gateway members are playing the main role in group formation and preventing these attacks.
