Eurecom IPv6 soft handover

The growing demand for high-speed wireless access to the Internet is the driving force behind the current trends to design All-IP wireless networks, whose Access Router and mobile stations use Internet Protocol for signaling and /or data transport. That will allow an ubiquitous IPbased access by mobile users, with special emphasis on the ability to use a wide variety of wireless and wired access technologies to access the common information infrastructure. The design of an All- IP wireless network requires an efficient and flexible handover management, independent of layer 2 protocol, which allows efficient mobile stations roaming between Access Routers. In this paper we propose new IPv6-based Soft-handover approach, which guarantee an efficient and flexible mobile handover between heterogeneous wireless networks.
