An enhanced Scheme for Reducing Vertical handover latency

Authentication in vertical Hand over is a demanding research problem. Countless methods are commenced but all of them have insufficiencies in term of latency and packet loss. Standard handover schemes (MIPv4, MIPv6, FMIPv6, and HMIPv6) also practice these shortages when a quick handover is desirable in several genuine circumstances like MANETs, VANETs etc. This paper will evaluate the literature of the work done in past and present for undertaking the authentication concerns in vertical handover and will put down a basis for building the latency and packet loss more effective in such a huge shared situation that can produce to an extremely bulky level. This effort will mostly focus on the existing tendency in vertical handover mostly with the authentication, latency and packet loss issues.
