To support fast and efficient handoffs, we propose a single protocol for both link layer (within IP subnet) and IP layer (across IP subnet) handoffs within a local domain. It is a complementary protocol to Mobile IP, in which Mobile IP deals with inter-domain mobility in the wide area. By combining routing table in IP layer and bridging table in link layer to form a single forwarding table, packets destined to a mobile terminal can be forwarded by simple table look-ups. When a mobile terminal moves, the new route can be established by table updates initiated by the mobile terminal. Comparing with Mobile IP, the proposed scheme does not need IP encapsulation and does not have triangular routing problem. In addition, the overhead and latency caused by interfacing the mobility management in link layer and IP layer are eliminated. Although link layer mobility management depends on the underlying wireless technologies in certain extent, the proposed scheme is general enough for most wireless multiple access protocols.
