本篇論文提出一個新的移動性網路管理機制應用於物聯網與智慧型運輸系統,以解決現 有的移動性網路管理機制中,換手延遲時間較長、控制訊息發送量高、電力消耗量較高以及 PMIPv6 無法提供 Global Mobility 的缺陷。因此本論文挑選 PMIP-MIP Interaction 為基礎,讓 PMIPv6 可以提供 Global Mobility,再針對其移動節點(MNNs)必須自行發送註冊控制訊息 進行改善,並且加入 NEMO 機制藉以減少控制訊息的發送量與移動節點的電力消耗量。此外,
本論文針對火車車廂內,建立一個小型的 PMIPv6 + NEMO 架構,使得使用者的感測節點與 Smart Devices 不用理會火車列車的移動,亦可減少其控制訊息發送量與電力消耗量。本論文 另外加入 MR-HA 用以記錄目前 MRTrain所在的 PMIPv6 Domain 位置,並且修改 MNN-HA 的 Binding Cache,將封包轉送到 MR-HA。藉此方式可以大量且有效地減少當火車列車在不同基 地台通訊範圍換手時,所產生的巨量註冊控制訊息。在數值分析中,本論文針對換手延遲時 間、控制訊息數量、電力消耗量與資料封包傳輸延遲時間進行分析,分析結果顯示出本論文 在資料封包傳輸延遲時間雖然有較高的延遲時間,但相較於其他移動性網路管理系統,本論 文的方法有更低的換手延遲時間、較少的控制訊息數量以及更少的能源花費,因此更適合使 用在未來 IoT 中資源受限的感測裝置上。本論文未來將持續在預先換手機制(Pre-Handover Mechanism)以及系統延展性(Scalability)上進行加強。
