| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 101 === 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.
