超寬頻技術在近幾年來獲得相當大的關注,IEEE 802.15.3a將其視為實體層技術的候選可能之一,配合IEEE 802.15.3的多重存取層標準,將可取代無線藍芽技術及有線的IEEE1394和USB2成為可攜式消費性電子產品間連結的介面標準。其高資料傳輸速率(可達480Mbps)及採用分時多工存取的特性,非常適合做為多媒體內容的傳輸載具。因此超寬頻技術將有可能成為家庭多媒體閘道器和其他影音電子產品間的傳輸介面,許多電子娛樂裝罝可透過多媒體閘道器下載Internet上的內容以供使用。
Internet上的資料流超過80%屬於傳輸控制協定(TCP)的類型,如何提高TCP在802.15.3上傳輸效率是相當值得研究的課題。可攜式的電子產品多靠電池供電,如何提高電源利用的效率,以延長使用時間,為另一個值得研究的焦點。在本篇論文中,提出了TCP在802.15.3上傳輸的方法,並加入了802.15.3所規範的省電模式運作。
Recently, Ultra-wideband (UWB) technologies have attracted considerable attention for its capability, high data rate to achieve 480Mbps, to wireless personal communications. In this thesis, the problem of TCP and energy efficient transmission in IEEE 802.15.3 WPAN based on UWB technologies are addressed. Also, a simple power-efficient scheme for TCP transmission in accordance with IEEE 802.15.3 WPAN standard is proposed and NS2 is used for evaluating the performance of this proposal. The scheme design is driven by two major factors. The first one is that the scheme should provide high TCP throughput in a piconet and low end-to-end delay for TCP packets. The second one is that the scheme should be energy efficient since most mobile devices typically are powered by battery and have limited power capacity. In order to meet these requirements, the energy efficient design at the MAC layer and Transport layer is taken into account by the proposed schema.
