MANET is having mobile platforms and is freely moving. In MANET the connectivity nodes changes frequently. The MANET network thus needs to be authenticated, where authentication is a form of authorization which gives access to system based on identity.
Keywords: Mobile Adhoc Network (MANETs), On-demand routing protocols, security Mechanisms, Anonymous protocol for MANETs, security attacks.
