| 摘要: | 下一代協同式網路提供未來寬頻、智慧型網路服務需求的重要關鍵技術。此種網路所能提供的高頻寬， 需藉由多種新技術： 如機會式(opportunistic) 、合作式 (cooperative)、感知性 (cognitive)、或利用如網路編碼 (network coding) 等數學運算的整合研究，方能發揮協同式網路的優勢，充分利用無線資源。本計畫的目標為「下一代協同式網路關鍵技術研究」，將規劃為二年期計畫，分為六個子計畫來執行，分別是：子計畫一：多輸入多輸出區塊傳輸系統中使用少量接收訊號之盲通道估測、子計畫二：無線協同網路前瞻接取技術之跨層研究、子計畫三：新世代合作式無線寬頻網路之臨機感知型媒介存取控制協定設計策略、子計畫四：機率式路由與各層無線通訊技術之跨層整合探討、子計畫五：無線協同網路之編碼認知性路由技術研究、及子計畫六：基於人智運算輔助定位分群之群組通訊在耐延遲網路的研究。具體而言，子計畫一、二著重在實體層，對傳輸速率和功率做最適當的調配。子計畫三著重在媒體層，提供感知型無線電的感知型借取演算法和隨機感知媒介存取控制協定。子計畫四、五、六著重在網路層。子計畫四著重在機率式路由的跨層設計，子計畫五著重在路由與網路編碼的結合設計，子計畫六則著重在耐延遲網路的環境下，結合路由、網路編碼、群體傳播、與能量考量的設計。子計畫五與子計畫六的結合可以讓網路服務在市區、郊區甚或山區都可以獲得此服務。藉由此二年期六個子計畫的研究整合，設計並提供創新性之協同式網路關鍵技術，成功滿足智慧寬頻網路服務需求。其所能獲得的理論基礎與實作經驗將能提供給未來類似技術的研究學者做為參考。In this joint project, we plan to study the next generation cooperative and collaborative wireless networking, in order to provide high throughput for the increasing demands of broadband wireless service. This project will last for two years and consist of six sub-projects, namely: Sub-project1: Blind Channel Estimation in MIMO Block Transmission Systems Using Few Received Blocks, Sub-project2: Advanced Access Technologies of Wireless Cooperative Networks—From a Cross-Layer Perspective, Sub-project 3: Opportunistic Cognitive MAC Protocol Design Strategies for New Generation Cooperative Wireless Broadband Network, Sub-project 4: The Cross-Layer Integration of Opportunistic Routing and Wireless Communication Technologies, Sub-project 5: Coding-Aware Routing in Wireless Cooperative Network, and Sub-project 6: A Research on Delay Tolerant Network based on Human Computation Assisted Geo-Clustering. Specifically, Sub-projects 1 and 2 will focus on PHY layer design for rate adaptation and power control of cooperative communication, Sub-project 3 will focus on MAC layer design for cognitive borrowing algorithm and opportunistic cognitive MAC protocol of cognitive radio, and Sub-projects 4, 5, and 6 will target the network layer issues for wireless cooperative networks. Among them, Sub-project 4 will focus on the cross layer design of opportunistic routing, Sub-project 5 will focus on coding-aware routing, and Sub-project 6 will focus on the issues in delay tolerant networks, and will study the combination of opportunistic routing, network coding, multicasting, and energy-efficient issues. Sub-projects 5 and 6 together will enable wireless service not only in urban areas, but also in suburban areas or remote villages. All together, we will achieve the objective of this joint project by the jointly cross-layer design for next generation cooperative networking to support many wireless services and applications in a broad area. 研究期間：10008 ~ 10107 |
