It starts with understanding the network mobility scenarios. Then the principle of mobile IP is revisited to serve as the basis for the subsequent discussion on the basic and advanced requirements and approaches for network mobility support. Finally, the network mobility research activities in the EU project OverDRiVE are reported. EU project. IETF NEMO working group. OverDRiVE. Beyond-3G systems. Mobile IP. Network mobility research.
