Wide-Area IP Network Mobility

Abstract

Abstract-IP network mobility is emerging as a major paradigm for providing continuous Internet access while a set of users are on the move in a transportation system. The intense interest on its support has led to the establishment of the NEMO IETF working group and a test-deployment by a major airline equipment vendor -Boeing -on major airline routes. However, the previously proposed solutions are either inefficient or may cause instability to the global Internet. In this paper, we propose WINMO, a simple, systematic, novel solution for wide-area IP network mobility using techniques including route aggregation, scoped update propagation, and packet mobility states. Our solution provides efficient routing when users travel both across autonomous systems (ASes) and within a single AS, generates minimal global routing overhead to prevent global instability, ensures good location privacy, and helps to defend against denial-of-service attacks. Furthermore, our basic scheme (without packet mobility state) is transparent to both clients and servers. Our extensive evaluations demonstrate the effectiveness of our mobility solution.

Floating ground architecture

“…As FGA takes as its design concept Smart Core, Dumb End hosts, and Intelligent Floating Routers, the required installation into existing components is limited to the mobile network side. NEMO extensions (UMA [16], MIRON [5]) require additional functional cooperation from existing components, while WINMO [10] introduces different component behavior with their extensions. On the other hand, FGA only replaces Mobile Router functionality of NEMO and does not require the cooperation of the access network.…”

“…There are plenty of solutions to tackle this nested NEMO problem [15]; Light-NEMO [20] uses tunnel concatenation, MIRON [5] configures CoA with address delegation cooperate with access router, HAHA [28] migrates distributed home agents at the infrastructure side, WINMO [10] uses BGP infrastructure to distribute optimized prefix of mobile network, Correspondent Router [27] introduces new router functionality at the correspondent node side to bypass the redundant path. While these existing solutions introduce additional functionality to the nonmobile network side (which is not the main entity involved by the movement), FGA only involves mobile entities to achieve route optimization.…”
