碩士 === 國立東華大學 === 資訊工程學系 === 97 === With the advances in wireless technology and the wireless terminal devices (such as: mobile phone, PDA, laptop) low price, the user can access anywhere, even in the transportation, to links to the information network, and freely access to the necessary Internet service in order to bring a great convenience. Has been how to achieve network Ubiquitous Computing environment for the majority of people are concerned about the current development issues, but it still has the needs of the integration of various technologies to build this environment, so the integration of the characteristics (such as: long distance, high bandwidth) of WiMAX wireless technology can accommodate to the wireless environment to promote related development of the ubiquitous network. The main purpose of this thesis was aimed at WiMAX wireless network environment, and researches the embedded pervasive systems and vehicular applications of related WiMAX network architecture, and combines to intelligent transportations. The content of this research contains the following three parts: research and development of embedded WiMAX modules, proposition of pervasive system framework, and the integration of WiMAX system modules and intelligent pervasive system. With this study achievement, it will apply the WiMAX protocols and the related services of pervasive network, and upgrades existing transportations to intelligent wireless access transportations, and combines with characteristics and the advantages of open architecture of the embedded system to provide the users with the enjoyment of the wireless access network environment, and also has the advantages of high performance and automatic services. Session Configuration and A/V OpenCORE modules of the pervasive system are proposed by this thesis. When the event of Session Lost occurred, the average delay time can be reduced 5.24% with the Session Configuration module. Through the A/V OpenCORE module processing, in the implementation of a single video streaming service, the A/V OpenCORE module can enhance the 23.29% throughput; On the other hand, in testing the implementation of the three video streaming services in turn, the A/V OpenCORE module can enhance the 15.95% throughput. This research not only integrates the WiMAX modules and intelligent pervasive system, but also verifies that the proposed Session Configuration and A/V OpenCORE modules of pervasive system will enhance the overall effectiveness and the execution to achieve high performance.
