當多媒體類型的網路服務應用愈趨發達的現今,使用者對網路傳輸即時性資料的需求也愈來愈高。在這樣的期望下,IEEE 802.16寬頻無線存取網路 ( Broadband Wireless Access ) 因此而誕生了。IEEE 802.16除了提供充裕的頻寬外,並且也支援網路服務品質保證的相關機制,因此非常適合傳輸多媒體資料。

在本篇論文中我們遵照IEEE 802.16中服務品質保證的規定,設計了一套新的排程機制。這套排程機制將會依照資料等級之不同給予對應的服務。在論文中我們將使用模擬來驗證我們的機制與原先機制在傳輸資料上效能的差異。最後經由實驗結果證明,我們的機制在傳輸即時性及非即時性的資料上,都能夠較原先的方法有更佳的傳輸量及延遲時間。
When multimedia types of internet service application develop more today, User’s requirement of internet transmission real-time data is more and more high. In today’s anticipating, IEEE 802.16 Broadband Wireless Access system ( BWA ) is born . In addition to provide sufficient bandwidth, IEEE 802.16 support concerned mechanism of Quality of Service ( QoS ), therefore it is suitable for transmitting multimedia data .

In this paper, we conform to the rules of quality of service in IEEE 802.16, and design a new schedule mechanism . According to difference of data level, the schedule mechanism will give corresponding service. In this paper, we test and verify difference of performance of transmitting data between our mechanism and original mechanism by emulation. Finally, by way of testing result, it prove that our mechanism is able to have better throughput and delay time than original mechanism in transmitting real-time and non-real-time data.
