MIH-Assisted PFMIPv6 Predictive Handover with Selective Channel Scanning, Fast Re-association and Efficient Tunneling Management

Extension of MIH for FPMIPv6 (EMIH-FPMIPv6) to support optimized heterogeneous handover

“…It provides sharing of MIHF-generated events.It also communicates the link-layer events. b) The MIH_LINK_SAP-which is an abstract media dependent Figure 5 PMIPv6 assisted MIH using fast handover procedure [12] [19] [21] interface between the MIHF and lower layer protocols stacks and it provides the media-specific SAPs for different link-layer technologies. c) The MIH_NET_SAPwhich is an abstract media dependent interface of the MIHF responsible for transport services over the data plane.…”

“…However, this scheme requires the buffering packets from both the LMA and the nMAG, which may result in the out-of-order problem. Therefore, they improved it by transient binding [21] and modified pre-registration procedure. After that, to provide the QoS guaranteed real-time services, Kim et al [9], optimized predictive PFMIPv6 handover scheme which supports the pre-registration via MIH_Net_HO_Candidate_Query request and response messages, and supports the pre-authentication with EAP.…”

“…At the same time, to reduce the handover delay, it adopts the prediction-based smart channel scanning [22]. Figure 5 shows its handover procedure [12] [19] [21] (In the following part, we note this scheme as fast handover solution).…”
