dc.description.abstract | 由於無線分封通訊技術的發展, 以及道路使用者對周遭資訊需求日漸強 烈 , 應用無線分封通訊技術於道路資訊服務系統, 已是各先進國家重要 研究項目之一。本研究探討應用R-CsMA多重存取於高速公路資訊服務系 統, 在正常車流條件下, 考慮服務成功率99%, 設計最佳的系統參數, 如: 封包大小、時槽數, 使得系統提供行動台最大資料量的服務。在此, 我們 提出三種服務: 向下服務(提供行動台接收信息)、向上服務( 提供行動台 傳輸信息)、向下向上服務(提供行動台傳輸或接收信息)。首先,我們建立 R-CsMA系統模型架構, 進行電腦程式模擬, 以期對三種服務系統尋找最佳 的系統參數。對具有頻道保留特性的"提供行動台傳輸資訊"之系統, 建立 數學模式, 以分析其系統向上通道使用效率。此外, 我們針對提供行動台 傳輸或接收資訊的服務系統, 選擇不同的閒置時槽存取法則: 非堅持性法 則、1 -堅持性法則、p-堅持性法則, 以分析其系統的服務績效。 In this study, we analyze the system capacity for a packet radio communication for highway application, based on a R-CsMA ( Reservation-based Channel-selection Multiple Access) protocal. Capacity of such a system depends on several factors, such as system data rate, packet length, number of slots in a frame, multiple access schemes, etc. The analyse are based on simulation models, which are established to include the considerations of normal traffic flow, vehicle speed, and 99% successful service rate. The objective of the models are to find the optimum parameters that will provide maximum effective communication data rate. We have proposed three different access schemes for idle slots : non-persistent, 1-prsistent , and p-persistent, to analyze their service performance. | zh_TW |
