快速換手FMIPv6之擷取路由預測機制

Abstract

快速換手行動FMIPv6,以IPV6位址Auto-Configuration特性，移動點在原網域已透過新網域路由器取得新位址.進入新網域只要完成AP連結,快速恢復網路通訊.移動偵測使用Layer 2觸發機制,在原網域提前獲取新網域訊息,減少延遲時間,加速了切換過程的完成.本研究目的分析探討FMIPv6移動路徑預測使用802.11優缺點,並在未來提出以歷始性記錄基礎架構,改善預測準確度。

In FMIPv6 protocol, using IPv6 address auto-configuration mechanism, Mobile node stay at home domain has capability to pre-allocate new address through router before entry new domain, The one thing mobile node has to do is finish associate with AP once it move to new domain and resumes communication rapidly. Movement detection rely on layer 2 trigger and exchanges neighbor information between Mobile node and router. Those mechanisms fasten handoff procedure and reduces latency. The article analysis method of using 802.11 protocol to predict movement .In the future ,we will propose history-base method to improve predict accuracy.
