摘要：In the recent years popularity of different wireless devices has increased by leaps and bounds. This is due to their portability, low cost and lesser energy consumption. But since these devices are wireless and don’t have any fixed infrastructure, they change their locations very frequently. As a result it becomes difficult to maintain an un-interrupted connectivity to these wireless devices. Situation becomes tougher when the Mobile Nodes reside in the vehicle, which is also in motion. We are now witnessing the emergence of mobile networks as a set of hosts, which move collectively as a unit, such as the ships and the aircrafts. One protocol widely used to maintain mobility is Mobile IP (MIP) or its version 6 (MIPv6). It is a better solution for host mobility but not for network mobility. A modified version based on MIP called Network Mobility Basic Support protocol (NEMO) was developed by IETF. But NEMO protocol requires a lot of global registrations and de-registrations during the handoff and could lead to heavy signalling overhead. To reduce this problem different micro mobility protocols such as Micro-NEMO and its enhanced version were developed. In this paper we have shown the motivations behind the developments of these protocols, their different versions and comparative analysis of their respective performances in terms of Data transfer time, Signalling time, Response time and Delay in mobile nodes.
