行動合作網通之無線訊號與訊息處理技術研究-子計畫五：機器間合作式和低功率無線傳輸設計

Abstract

本計畫著重於解決一些機器對機器國際通訊標準制定 (IEEE 802.16p, LTE-A)上所面臨的重要議題，並特別針對無線資源配置與排程、低功耗、協同式傳輸與接收、以及自我組織等議題進行深入的研究與探討，其如以下四項子計畫所列: #1; 協同式機器對機器通訊 #1; 在正交分頻多工系統下之高能量使用效率之機器對機器通訊資源配置方法 #1; 針對機器對機器通訊之隨機接取分析 #1; 機器對機器之互聯式通訊在子計畫一中，我們開發了在多重輸入多重輸出系統(MIMO)系統下協同式傳輸之牌程與資源配置方法。在子計畫二中，我們開發了低功耗資源配置方法以及低功耗機器分群演算法以節省機器網路的總體功耗。在子計畫三中，我們特別分析了機器裝置分佈情形的隨機性與複雜性，並分析了大量隨機分佈之機器裝置對系統所帶來的影響。針對以上，我們更分別評估探討了機器裝置在各種不同隨機分佈 (Homogeneous Poisson Point Process, Poisson clustered random process)的情境。在子計畫四中，我們以上述三個子計畫為建立機器通訊架構的基礎，將機器通訊架構更進一步地延伸到感測智慧網路，並藉由發展線上互連控制器，我們整合了上層通訊端的需求以及端對端(end-to-end) 的應用目標，發展成為一個具有高度整體性、多應用性的無線感測網路。

In this proposal we aim to resolve some of the issues raised by Machine-to-machine (M2M) Standardization Committee, LTE-A and IEEE 802.16p. In particular we focus on (c) Resource allocation & scheduling, (e) Low power consumption, (f) Cooperating transmission and reception and (g) Self-organization issue. We propose four subprojects, namely: • Sub-Subproject #1: Cooperative Communication for M2M • Sub-Subproject #2: Energy-Efficient M2M Resource Allocation for OFDMA Networks • Sub-Subproject #3: Randomness analysis in M2M Communication • Sub-Subproject #4: Associative Communication in M2M In the first subproject cooperative transmission is being developed by investigating the user scheduling and resource allocation in MIMO Systems. In second subproject we develop a low power resource allocation schemes by approaching self-organization issue and propose Machine Device Grouping and Coordinator Selection for Energy-Saving M2M. In the third subproject we focus in particular on the random and complex nature of M2M communications. We analyze the influence of the large amount of randomly located machines in the M2M communication via means of stochastic geometry and evaluate scenarios based on homogeneous Poisson Point Process (HPPP) and Poisson clustered random process. Using the first three subprojects as a firm basis for establishing the architecture of M2M communications on the transmission level, in the fourth subproject we extend this architectures into intelligent network of sensors. By developing the online association controller we incorporate the higher level demands and end-to-end application goals into the structure of wireless sensor networks.
