Managing fast mobility in wireless multi-hop networks with LISP

Abstract

The Locator/ID Separation Protocol (LISP) has been developped in recent years in order to solve the scalability issues the current Internet Architecture is facing. Differently from the current addressing system, where end-systems' identifier and location information are merged in one single entity, i.e., the IP address, LISP aims at using two different address spaces to identify and to locate end-systems. Such a separation turns out to be very useful in the context of networks with highly mobile end-systems, where the information "who is where" changes rapidly. In the present paper, we propose and show how LISP can be used in the context of wireless multi-hop network in order to provide support for fast mobility to end-systems. Furthermore, we present our efforts to provide a LISP implementation, using the Click Modular Router, running over the BOWL (Berlin Open Wireless Lab) testbed deployed in our Labs.
