Mobility is the ability to move freely. And this free movement of any node can only be done by an Internet Engineering Task Force (IETF) Standard Communication Protocol i.e. Mobile IP. A mobile node always passes through many of the processes of handovers as it is changing its networks again and again. And these handovers increases latency. This paper evolved with a survey on handover latencies with many of the extensions of Mobile IP by discussing and comparing them and their related problems with latency and also proposes the best scheme for it.
