Abstract

IPv6 has an inherent characteristic of supporting mobility. When a mobile host (MH) undergoes handoff from one link to another, it needs to obtain a new Care-of Address (CoA) at the New Access Router (N.AR) as soon as possible in order to be able to send and receive IP packets. The basic MIPv6 is the case that MH acquired CoA after moving to handoff expected candidate region. MH obtained CoA before handoff, MH have experienced in reduced handoff latencies. The latency involved in forming a new CoA in MIPv6 comes mainly from both Neighbor Discovery (ND) and Duplicate Address Detection (DAD) in stateless auto-configuration scheme. As MH obtained CoA before handoff and P.AR is using a buffer management, our proposed method is fast and lossless. It is expected that DAD check is indispensable to detect the bad guys who use MH's address by stealth.
