Abstract

The Locator Identifier Separation Protocol (LISP) has been made as an identifier-locator separation scheme. However, the issue of handover for mobile host is still a serious challenge in LISP. The existing LISP-based handover schemes tend to induce large handover delay and packet loss. To overcome such problems, we propose a new handover control scheme, in which the Map Request and Reply messages are exchanged between old access router and new access router after handover. Then, the locator update operation is performed so as to provide the route optimization. From the ns-2 simulation results, it is shown that the proposed scheme can give better performance than the existing LISP-based schemes in terms of handover delay and throughput.
