ID/Locator Split-Based Mobility Scheme for Heterogeneous New Generation Network

The new generation network or the future Internet should treat mobile hosts as first-class objects and allow them to move freely across different networks that use heterogeneous protocols. For this purpose, this paper presents a mobility scheme, designed on the basis of the ID/locator split concept. The scheme provides mobility support from the identity layer, a shim layer inserted between the transport and network layers in the new generation network architecture. Mobility functions are independent of network layer protocols, thus they support mobility across heterogeneous network protocols. These functions are distributed in both end hosts and edge routers so that the scheme provides seamless mobility by reducing handover delay and consequent interruption in communication sessions.
