異質無線網路持續連線的整合機制以WLAN和HSDPA為例

拜科技進步所賜，電腦的演進從早期的桌上型電腦到筆記型電腦，越做越小，到現在幾乎人手一台的平板電腦以及智慧型手機，也因為這類行動可攜式產品的普及，以及目前正熱門的雲端運算的概念，推動無線網路技術必須朝向高頻寬以及高移動性發展，然而目前的各種無線網路技術似乎都還無法滿足目前的需求。本論文中提出一個基於Mobile IP技術改良後的系統，來整合不同的異質無線網路。在Mobile IP 技術的改良方面，首先透過簡化原本Mobile IP中的功能實體元件，來達到簡化此系統實現的複雜度。接著提出一個主動預先註冊機制，改進原本Mobile IP中因為Mobile Node移動，向Home Agent註冊目前最新的位置時，而導致的斷線。最後配合目前雲端運算的概念，此系統也基於保持續連線的前提下，以WLAN以及HSDPA這兩個異質無線網路技術為例，提出一個基於兩異質無線網路技術特性的無縫換手機制。最後透過對本論文中所提出系統做評估以及分析，此系統可以成功的達到異質無線網路的整合以及無縫換手。

As for the advancement of technology, pushing wireless network technical must tend to high bandwidth and high mobility developing, however presently all kinds of wireless network technical seems to can’t meet present demands. In this present paper proposed a system based on improved Mobile IP technology, to integrate different heterogeneous wireless network. In Mobile IP technology improvements, first by simplifying the originally Mobile IP functionality physical components, to achieve simplifies the complexity of this system realizes. then proposed that registers the mechanism in advance on own initiative, for improvement in originally Mobile IP cause of Mobile Node movement, as registration current new position from Home Agent, which resulted in the offline. finally coordinates the present cloud computing conception, this system also based on keep connecting under premise, take WLAN and HSDPA these two heterogeneous wireless network as an example, proposed that this two heterogeneous network handoff mechanism. Finally, this paper through the system to do the proposed assessment and analysis, this system can be successfully achieved the integration of heterogeneous wireless networks and seamless handoff.
