本篇論文為基於IEEE802.16e網路下,第三層換手機制的研究。主要是針對IETF所提出來的Fast Handover for Mobile IPv6會因為準備時間不足而進入Reactive mode,造成較大的延遲以及封包遺失,因此在這使用Pre-Binding Update的方法,提前做第三層的換手準備,以加速第三層換手動作,並且使用MIHF(Media Independent Handover Function)來減少訊息的傳遞。在論文的最後,利用模擬的方式對本篇論文所提出的方法與”Fast Mobile IPv6 Handovers over IEEE 802.16e Networks”來做比較,以及數值分析的方式來比較不同方法的Signaling Cost。
This thesis is concerned with the research of layer 3 handover scheme based on IEEE 802.16e network. The IETF RFC-4068 “Fast Handover for Mobile IPv6” with reactive mode causes insufficient time to prepare layer 3 handover. When an MN perform reactive FMIPv6 handover, it will experience large latency and packet loss. In this thesis, we use Pre-Binding Update at network discovery to speed up layer 3 handover , and use MIHF(Media Independent Handover Function) to reduce amount of message exchange. In the final simulation , results of proposed Pre-Binding Update scheme are compared with those of “Mobile IPv6 Fast Handovers over IEEE 802.16e Networks” which is a draft on IETF , and results of numerical analysis are presented to compare the signaling cost of different layer 3 handover scheme.
