Network-based distributed mobility control in localized mobile LISP networks

In Locator-Identifier Separation Protocol (LISP), the existing mobility control scheme is based on a centralized approach, in which the Map Server is used as a mobility anchor. However, such a centralized scheme has some limitations, including traffic overhead at central server, service degradation by a single point of failure, and larger handover delay. In this Letter, we propose a network-based distributed mobility control in localized mobile LISP networks. From numerical analysis, it is shown that the proposed distributed scheme can provide better performance than the existing centralized scheme in terms of the signaling loads for binding update/query and the handover delay.
