GRS: Global Resolution Service for mobility support in the Internet

As it becomes a common need to support mobility in the Internet, there is a growing trend towards providing a general mobility management function in the protocol stack by resolving identifiers of mobile nodes to their locations. However, current mechanisms have drawbacks in both performance and functionality, especially when they are partially deployed. In this paper, we propose a Global Resolution Service (GRS) offered by Resolution Service Providers (RSP), which resolves identifiers in a flexible way according to diverse mobility scenarios. Simulation results show the advantages of our approach compared to existing solutions in terms of both flexibility and deployability.
