Fast Handover for Upstream Traffic in Mobile IPv6

The minimization of downstream handover delay in Mobile IPv6 (MIPv6) has been the target of many researchers. However, the handover delay in the upstream traffic has not been considered equally important. But for example, in Voice over IP (VoIP) or in Video Conference both traffic directions are of equal importance. In this paper we propose the use of a Hand-ofAddress (HofA) to minimize the delay in a Mobile Node (MN)'s upstream traffic flow in Mobile IPv6 based networks. By using a specific HofA the MN can send upstream traffic during the Binding Update (BU) process.
