This article surveys the major existing approaches and proposes a novel architecture to support mobile networks in network-based, localized mobility
domains. Our architecture enables conventional terminals without mobility
support to obtain connectivity either from fixed locations or mobile platforms
(e.g., vehicles) and move between them, while keeping their ongoing sessions.
This functionality offers broadband Internet access in automotive scenarios such
as public transportation systems, where users spend time both in vehicles and at
stations. The key advantage of our proposal, as compared with current
alternatives, is that the described mobile functionality is provided to
conventional IP devices that lack mobility functionality. We also performed an
experimental evaluation of our proposal that shows that our architecture
improves the quality perceived by the end users.
