我們在直接序列展頻技術的極寬頻無線通訊網路上,使用IEEE 802.15.3高速無線個人網路的媒體存取控制層協定,因此在媒體存取控制的研究與應用方面,必須參考802.15.3的標準,本研究首先對802.15.3標準進行了詳盡的了解。
為了在這個極寬頻高速率的網路環境下進行更多樣化的應用並且擴大網路的涵蓋範圍,我們設計了在多個微網路之間進行互相連結的機制。並且利用這樣的機制以及極寬頻無線通訊網路的特性,進行整體網路覆蓋環境下的多段資料傳輸。
對這個架設於極寬頻無線個人網路之上的資料傳送系統,我們針對環境中介接不同微網路間的橋接裝置所會遭遇的轉向問題,設計了一套集中式演算法,將橋接裝置的轉向策略加以排程,以解決在多個微網路間傳遞資料所造成資料遺失及延遲等問題。
為了驗證演算法的正確性及效能,我們也針對802.15.3的網路環境,建構一個MAC層的模擬平台。在此模擬平台上進行協定之實作,以驗證比較協定之效能,並提出缺點與改進方法。
The direct sequence spread spectrum (DSSS) ultra-band wireless networks employ IEEE 802.15.3 media access control (MAC) protocol. We explore carefully the IEEE 802.15.3 standard in detail in our study for multi-piconet applications. In order to variegate the application on high-rate UWB WPANs and expand the network coverage, we regulate the inter-piconet connection scheme, so that we could transmit data between different piconets by multi-hop relay.
Then, we propose a centralized scheme to schedule and control the switching policy of bridge devices in this environment to solve data-loss and delay problems caused by multi-hop transmissions. Furthermore, a simulation platform for 802.15.3 network is built to examine performance of our proposal schemes. Some suggestions are proposed according to the simulation results.
