摘要:	由於發展通訊電子設備與無線通訊科技，而使得寬頻無線網路愈來愈普及。寬頻無線網路是由多個擁有通訊能力的移動台與基地台組構成的。基地台具有射頻資源分配、服務排程與資料分類所服務網路的能力，而使此網路可以帶來各式各樣的應用。許多公司與研究組織已陸續投入研發資源在寬頻無線網路的相關技術與應用，而車用移動存取技術便是其中一項重要應用項目。為了實現車對車與車對路之間的通訊，發展一個支援多點跳躍的車用網路變成一個重要且極具前瞻性的課題。本群體計劃名稱為「以 IEEE 802.16e Multi-hop WMAN 為基礎之行動車輛網路系統前瞻設計」，目前此研究團隊已針對目前可應用於相對短距傳輸之車用網路通訊協定 IEEE 802.11p 技術充分研讀，為了支援更適合於未來都會行車寬頻網路，我們計劃以 IEEE 802.16e/j/m 都會網路長距傳輸之特性進而設計一套完整多點跳躍車用協定網路 (Multi-hop Vehicular Protocol Networks - MVPNets)。此外，本群體計劃將以具有完整網路模組之 QualNet 模擬器為平台針對所設計之車用通訊網路協定、網路佈建與規劃、路徑選擇、服務保證之換手機制、定位服務等等需求，開發本計劃相關模組。因為QualNet 模擬器尚未支援 IEEE 802.16e Mobile WiMAX 之模組，為使本計劃可以順利執行與完成，群體計畫之總計畫負責撰寫支援 IEEE 802.16e Mobile WiMAX 模組並開發相關模組以利對MVPNet 進行系統評估。MVPNets 相關的核心技術將細分為四個子計劃執行，子計劃一將詳細設計與開發多點跳躍車輛網路的媒介擷取控制層協定；子計劃二針對保證服務品質換手機制與多點跳躍路徑選擇方法等相關網路議題做分析與探討，以設計出移動換手機制與有效的路由交換機制於車用無線網路上；子計劃三以交互參考點運算機制來改善於進入建築物內環境(如室內停車場)對車輛之定位精確度，並有效降低建立RadioMap 的成本。全體計畫執行期限規劃為二年期，此計畫開始進行時將進行網頁相關註冊並隨時對外公佈目前所有計畫的研究內容與進度；進而冀望此網站能成為第一個提供相關 WiMAX 車用網路相關研究的資訊交換平台來加強此群體計劃產出的前瞻性、可行性與認同度。 ; Wireless broadband access networks are now in widespread use due to the development of micro electronic and wireless communication technologies. Many industrial companies and research institutes have began to study and to develop the related technologies for various applications of the wireless broadband access networks, especially in vehicular access applications. In IEEE 802.16 wireless broadband access networks, the data classifying, service scheduling and radio resource assignment are controlled by base stations, and the served mobile stations shall act according to its serving base station or its leading relay station. In order to achieve vehicle-to-vehicle and vehicle-to-roadside communications, we put our focus on the designs of the multi-hop vehicular protocol networks (MVPNets). We have been studying relative vehicular ad hot network technology such as short-transmission-distance IEEE 802.11p. This proposal aims to design of MVPNets based on long-transmission-distance IEEE 802.16e multi-hop WMAN. For speeding up the evaluations of the system performance, the popular QualNet simulator is adopted as the platform, and we will develop the related modules such as the proposed vehicular network protocol, the cell planning method, the routing path selection with QoS-based handover mechanism, location based services, and so on. In order to successfully carry out this integrated project, we divide our core techniques of MVPNets into four sub-projects, where the first one is to design the detailed specifications for multi-hop relay features, functions and interoperable relaying to extend coverage and system capability of 802.16e networks, the second one will solve the QoS-based handover, multi-hop path selection and related network issues and the fourth one is to provide the accuracy of location positioning, especially in indoor environment, and to reduce the overhead of radio maps by Reference Point (RP) scheme. During the development of integrated project, we will initially register a domain name for the advanced researches on WiAMX-based vehicular networks. All the related materials and achievements will be disclosed to world-wide researchers who are interested on such topic. We hope this project can become the first research team working on such topic and recruit more world-wide researchers to consolidate the researches in the near future. ; 研究期間 9708 ~ 9807
