窄帶物聯網是一種支持廣域物聯網應用的技術，該技術標準由第三代合作夥伴計劃標準從第十三版開始提供。本篇論文針對“窄頻物聯網隨機存取通道資源配置之優化”論文再做延伸探討。我們在時槽式阿羅哈系統下，在“重複機制”與“重傳機制”觀察單一用戶與多重用戶在不同的加性高斯白雜訊 下是否進行隨機後退對延遲和能量消耗的影響，最後觀察重複與重傳在不同組合下在不同的瑞利衰落對成功機率影響；並且我們藉由模擬驗證分析公式。
The Narrowband internet of things (NB-IoT) is a technology to support wide area Internet of Things (IoT) applications and the standard is provided from 3rd generation partnership project (3GPP) standard start at Release 13. This paper continues the work of the paper " Optimization of NPRACH Resource Configuration in NB-IoT". Under the slotted Aloha system, in the "repetition mechanism" and "retransmission mechanism" to observe in a single user and multiple users with non-random backoff and random backoff effects on the delay and energy consumption under different Additive white Gaussian noise, and finally observe the repetition and retransmission in different combinations under different Rayleigh fading effects on the probability of success, and we use the simulation to verify the analytical formula.
