Vertical Handoff Reduction Mechanism Using IEEE 802.21 Standard in Mobile IPv6 (MIPv6) Network
Low handoff latency and minimum packet loss are envisioned important factors for the next generation Mobile IPv6 (MIPv6) based heterogeneous networks. To meet these constraints IEEE 802.21-Media Independent Handover (MIH) was introduced to enhance the Quality of Service (QoS) of the networks. The MIH provides link layer information to the network layer to reduce handoff latency while the Mobile Node (MN) changes its active interface to another interface. In this paper an additional entity "Smooth Handoff Controller" (SHC) and an algorithm are proposed to select alternative interfaces in advance while MN is using an active interface.
