Infrastructure-based route optimization for NEMO based on combined local and global mobility

ABSTRACT

Global mobility management protocols have been standardized and are gaining more and more momentum for deployment. At the same time network-based local mobility management has been identified as an important cornerstone for an overall mobility management framework and is currently covered by PMIPv6. However, local and global mobility management are separated and serve different purposes with little interaction. In the light of the work on NEMO route optimization we propose to combine both approaches more tightly, reusing existing functionality. We show how PMIPv6 can be used to build a network-based route optimization procedure for NEMO/MIPv6 based on globally distributed Home Agents. We also show that this approach can directly benefit from future evolvements of the PMIPv6 protocol.
