摘要

EPON-WiMAX整合網路整合了可提供大頻寬的乙太被動式光纖網路(Ethernet Passive Optical Network, EPON)及以OFDM/OFDMA的技術為基礎的全球互通微波存取行動網路(WiMAX)，被視為未來最具潛力的有線網路與無線網路整合方案之一。 EPON-WiMAX整合網路優點包含了(1) 提供寬頻網路存取，(2)支援移動性用戶，以及(3)降低網路設計與維運成本。
但是目前EPON-WiMAX整合型網路上，大部分的研究都是在設計上行封包排程或頻寬分配，而下行封包排程及頻寬分配的相關研究並不多，因此本研究利用EPON-WiMAX的特性，加入合作傳輸的技術，設計了下行鏈路的資源分配方法。我們利用合作傳輸的優點，設計出合作傳輸的策略，以提昇整體的系統產能，並且保證各種連線的服務品質。我們的模擬結果顯示採用合作傳輸可大幅提昇系統的效能。

Due to the demand of multimedia application services increase in recent years, and these applications, such as high definition TV (HDTV), video on demand (VoD) services, need much more bandwidth than other application services. As a result, the technology of broadband access is becoming more and more important. Integrating Ethernet Passive Optical Network (EPON) and Worldwide Interoperability for Microwave Access (WiMAX) has been considered as a very promising solution for broadband access. Features of EPON-WiMAX integrated network include (1) provide broadband access technologies; (2) support mobility; and (3) reduce the planning and operation cost.
Although EPON-WiMAX has received many attentions in research, yet most of the previous researches focus on the uplink packet scheduling and bandwidth allocation. Thus, in our research, we focus on the downlink scheduling and resource allocation problem. Our simulation results show that the proposed algorithm is able to increase the system throughput while guaranteeing the QoS of different classes of traffic.
