Mobility-aware MPLS in IP-based wireless access networks

Many domain-based micro-mobility schemes have been proposed to improve deficiencies of Mobile IP. The micro-mobility schemes provide efficient and fast handoff by localizing mobility impacts when the movement is within a domain. However they lack QoS support. This paper proposes mobility-aware MPLS as a micro-mobility scheme. The proposed scheme provides an efficient micro-mobility with continuous QoS support by combining the advantages of MPLS, such as IP QoS support, with the advantage of host-based micro-mobility schemes, such as low-latency handoffs.
