....knowledge of the new access point prior to handoff. The latter does not rely on any such knowledge, but attempts to recover packets from the old access point after handoff. The proposed seamless handoff extensions for Hierarchical Mobile IP operate along similar lines advocating bi casting [28,29], and buffering and packet forwarding [30,31] Figure 13 shows the effect of these handoff improvements for Cellular IP and Hawaii. We have plotted the average packet loss (negative values) or duplication (positive values) as functions of Cellular IP cross over delay and Hawaii buffering delay, ....

These proposals are Hierarchical Mobile IP [17] and its extension for the regional paging [18] Fast Handoff [12] Proactive Handoff [3] (see also [11] and finally TeleMIP [14] that is more an architecture than a real protocol. We also include in the comparison Cellular IP [5] HAWAII [33, 34] and EMA [25, 24] All these protocols are the result of the standardization process within the IETF Mobile IP [15] and the Seamoby [16] ....

....basis of interactions between FAs. Hierarchical Mobile IP [17] is an extension to Mobile IP that supports a hierarchy of FAs between the MN and the HA. Several improvements to Hierarchical Mobile IP, including a paging mechanism, have been proposed in [18] Fast Handoff [12] and Proactive Handoff [3] are two similar proposals based on Hierarchical Mobile IP with improved handoff mechanisms. TeleMIP [14] adds some load balancing features to the basic principles of Hierarchical Mobile IP. A basic network model for these proposals is shown in the figure 10 (left) Here we have a set of WIPPOAs ....

....loss during handovers; whilst HAWAII can optionally use dual casting from the crossover router, and it appears that this capability could also be added to MER TORA if required. Regional Registration uses standard MIP move detection mechanisms, extended if necessary with fast handover support [20] [26] [27] and smooth handovers as specified in MIP Route Optimisation [2] Similarly, both HAWAII and MER TORA can optionally deliver, from the old to the new BS, packets that would otherwise be lost during handover. There are differences, however: in the Single Stream Forwarding sub scheme HAWAII ....
