On the Design of Micro-Mobility Scheme for Mobile Networks

After 90’s, the improvement of production and material, more and more mobile devices become common and more and more people use them everyday. At the same time, the growth of Internet let people communication tightly. So when wireless technology is invented, it bundles mobile devices and Internet, people now can access Internet any time and any place. But because the limit of application and protocol, most mobile devices just have “Portable”, not “Mobility”. For this purpose，”Mobile IP” is proposed in 90’s, we hope it can help us to build a mobile environment. But we need a management scheme to manage more and more mobile devices, so a new field “Mobility Management’was born. Now, the main issue Mobility Management concerned is about “Host Mobility”, but next big issue is “Network Mobility(NEMO)”. Because when everyone has mobile devices, a large number of mobile devices will aggregate at the same place, for example, Bus or boat. Those devices will access internet at the same time, it is an un-efficient procedure, and they maybe access the same entity for the same information. So a new protocol “NEMO Basic Support” is proposed, it is designed for a Mobile Network. But this document is a basic standard, still have many drawbacks.
The contribution of our work is combine Micro-Mobility and NEMO. Initially, NEMO do not have Micro-Mobility scheme. And we solve the problems which are result from the combination of Micro-Mobility and NEMO. Our target is improve the efficiency of NEMO, let user can get more faster experience.
In our evaluation, we use four criteria
1. Number of Binding Update
2. Hand-off latency
3. Packet overhead
4. transmission cost
to evaluate our work is better than previous works
