設備間直接通訊(Device-to-Device Communication, D2D Communication),通常由基地台(Base Station, BS)分配網路資源,透過頻譜的重用(Reuse),提升系統的效能及頻譜使用率。然而在高密度的都會環境中,會產生大量的設備需要分配資源,導致BS運算負荷過大,增加資源分配的延遲時間,產生網路效能下降的問題。
過去研究多以使用蜂巢網路的手機用戶(Cellular User Equipment, CUE)為主,D2D的使用者(D2D User Equipment, DUE)為輔的方式來做資源分配,但這樣會產生一個嚴重的問題:為了避免干擾,DUE不能和鄰近的CUE使用相同資源,但在資源有限的情況下,會產生DUE資源選擇不多,沒辦法獲得最好效能的問題。
為了避免此問題,本論文提出了一個針對高密度都會環境裝置間通訊之資源分配機制,透過思維的改變,多數UE使用D2D而非過去Cellular的溝通方式,並搭配著色理論來做資源的分配,算出最佳的資源分配結果,達到提升效能的目的。我們利用數學分析,找出方法所能夠提供最佳效能,並以模擬實驗輔佐,結果證明我們的方法能夠有效提升整體系統效能。


In order to improve system capacity and spectrum efficiency, device-to-device (D2D) Communication is used. It reuses the resource of cellular network which is allocated by the base station (BS). I consider D2D Communication with high density in the urban. In this scenario, the BS frequently reallocates the resource to the devices. It increases the delay time of the resource allocation and decreases the system throughput as well as increasing system overloading.

Most of research allocated the resource to the cellular user equipment (CUE) before the D2D user equipment (DUE). The DUE cannot reuse the same resource to as it is nearby the CUE. In the situation of limited resources, DUEs may not have many choices. Thus, the system cannot obtain the best throughput.

To solve this problem, I propose a resource allocation method considering high density situation. Most of UEs use D2D mode rather than cellular mode and adopt coloring theory to allocate the resource. I use mathematical analysis to find out the upper bound of system throughput. Simulation results show that the proposed scheme significantly improves the system throughput and spectrum efficiency.
