NEMO-based mobility management in LISP network

Extending the basic Locator Identifier Separation Protocol (LISP), LISP-MN has been proposed to support mobility. However, LISP-MN only supports host-based mobility, and has some limitations in network mobility scenario. With the number of mobile nodes (MNs) as a group roaming among different network domains becoming larger, the signaling overhead in the system linearly increases. In this paper, we propose a NEtwork MObility supported scheme in LISP network (NEMO-LISP). In NEMO-LISP, a Mobile Router (MR) is introduced instead of a group of MNs to implement the registration and handover processes. Numerical performance analysis results show that NEMO-LISP can significantly reduce signaling overhead in the system than the existing LISP mobility scheme.
