A novel dynamic mobility management scheme in LISP architecture

LISP is an important development and implementation effort toward the resolution to the Internet routing table scalable issues. Although the LISP is based on the idea of the Locator/ID separation, it could not support mobility very well until now. This paper proposes a novel dynamic mobility management scheme in LISP architecture. It improves the LISP by introducing three name spaces and two mapping systems. By dynamic configuring the IDs to the mobile nodes, the proposed scheme could provide flexible mobility support with lower overhead, while maintaining the scalability and aggregatability of the global ID/locator mapping system. Furthermore, a fast location update method is presented in the proposed scheme to provide smooth handover. The proposed scheme is evaluated by comparing with the LISP Mobile Node in handover cost and handover latency.
