Mechanisms for resource reservation in mobile IPV6 networks

Mobile IPv6 (MIPv6) has been proposed to support host mobility in the next generation mobile networks. With the development of various multimedia applications, the requirement for QoS guarantee in such systems is coming. In this paper we first present an overview of RSVP extensions for reserving resources in mobile networks. We divide existing researches into four aspects: management of resource reservation, re-establishment of reservation path, design of mobile agent and integration of RSVP and mobility management. For each scheme we describe the basic idea and make comments on the advantages and disadvantages. Then we propose a QoS guarantee scheme in Fast Handovers for Mobile IPv6 (FMIPv6) architecture, using some mechanisms mentioned previously. Finally we draw the conclusion and present some future work.
