近幾年線上影片直播(Video Live Streaming)在無線移動網路(Wireless Mobile Network)當中已經成為一個非常熱門的應用(Application),但是直播也增加了行動網路的骨幹網路(backhaul)與無線電存取網路(Radio access networks)對於頻寬上的需求。為了減輕這項應用在頻寬資源上的佔用,結合移動式邊緣運算(Mobile Edge Computing, MEC)與群播(Multicasting)技術的解決方案自然成為了合適的選項。
我們之前研究了無線資源的最佳化管理(optimal radio resource management),其中包含modulation and coding scheme (MCS) selection、radio resource blocks allocation與Forward Error Correction(FEC),以此來幫助MEC在LTE networks進行多播。我們提出了一個以maximizing marginal gain and minimizing marginal loss(MGML)概念為基礎的啟發式演算法(heuristic algorithm),實驗結果顯示得到的答案與最佳解相比也是非常接近。
本論文著重在加入device-to-device(D2D)通訊技術,以提高用戶體驗(Quality of Experience)。本論文發現透過Cellular Network當中訊號雜訊比(Signal-to-noise ratio, SNR)較好的使用者裝置(User Equipment, UE)與訊號雜訊比較差的使用者裝置進行D2D傳輸,可幫助訊號雜訊較差UE能夠找回在Multicast傳輸當中遺失的內容,藉此提升整體系統的效能。
