| dc.description.abstract | 為了支援高流量的HD 影片 (High Definition video) 無線傳輸，每秒數十億位元(multi-gigabit per second) 的資料傳輸率是必須的。為了要支援每秒數十億位元的資料傳輸率，使用不需使用執照的60 GHz 頻帶中的7 GHz 頻寬成為了最可行的辦法。為了補償60 GHz 頻帶的快速能量衰減，訊號傳輸需要靠指向型天線增加傳輸距離。使用指向型天線帶來許多設計上的議題，像是指向性隱藏節點問題和空間重複利用等。指向性隱藏節點問題在節點互相尋找相鄰節點時成為一個重大的問題。
在60 GHz通訊中的實體層 (PHY layer)、媒介存取控制層 (MAC layer) 以及HDMI協定轉換層 (protocol adaption layer)，ECMA-387通訊標準提供了完整的解決方案。ECMA-387提供了相鄰節點搜尋的協定。搜尋的機制是基於封包廣播和隨機轉向的指向性天線。隨機轉向的指向性天線使得相鄰節點可以將天線的指向對方以發現彼此。但是這樣的搜尋機制無法保證兩個節點在限定的時間內會將天線指向彼此。 在論文中，我們提出一個節點分別以不同的指向性天線旋轉速率做封包廣播以及掃瞄的協定，並以此協定保證兩個節點必然會在限定的時間內將天線指向彼此。我們在OPNET Modeler中實現這個協定並證明此協定的表現。我們另外也將指向性天線中的旁葉效應所造成的影響加入考量並模擬。我們也模擬了ECMA-387通訊標準中的多樣節點共存協定。根據模擬的結果，我們可以使用最好的參數設定使得節點在不同的網路環境中有最好的表現。 | zh_TW |
| dc.description.abstract | To support high-volume transmission such as wireless high definition (HD) video streaming,
multi-gigabit per second transmission is needed. The unlicensed 60 GHz band with 7-GHz bandwidth has become the most feasible solution to support such high data rate wireless communication. Directional antennas are used to compensate high attenuation in 60 GHz band so as to extend the transmission range. The use of directional antennas raises new issues such as directional hidden node problem and spatial reuse. Directional hidden node problem is the major problem for wireless devices to discover each other. The ECMA-387 standard is a total solution for the 60 GHz communication, from PHY layer, MAC layer to the HDMI protocol adaptation layer (PAL). The ECMA-387 standard proposes a protocol to enable automatic neighbor discovery. The discovery mechanism is based on self advertisement with random switching of antenna sectors. With random switching, wireless devices may point their antennas to each other (so called match in direction) and thus, discover each other. However, such a neighbor discovery mechanism does not guarantee the time of match in direction. In this thesis, we proposed a differential-rate switching protocol to guarantee the time of match in direction. We implemented the protocol in Opnet Modeler and showed the performance guarantee. We also conducted simulations to study the impacts of side lobes of an imperfect directional antenna on the performance. Coexistence protocols of the ECMA-387 standard was also implemented and simulated. With the simulation results, we can find the best settings according to different network environments. | en |
