本篇論文利用遞迴式競爭用戶估計法對小資料傳輸應用提出分析模型，分析模型包含單位時間資料流量、封包失敗機率、平均存取延遲時間及平均存取延遲時間之變異數。針對有限數量的使用者依據不同服務性質分類於不同類別。本論文所提出的分析模型可以精準地預測在不同類別下分別可依照服務性質選擇應用不同的傳輸協定 (立即傳輸協定，延遲傳輸協定) 、不同的後退演算法 (二元指數後退演算法，均勻後退演算法) 及不同重傳次數上限的小資料量傳輸效能。

This paper presents an iterative contending-user estimation method to analyze the normalized throughput, the packet-dropping probability, the average access delay, and the variance of the access delay for finite-population slotted ALOHA system supporting multiple access-class traffic. We demonstrate the way to accurately predict the access delay of small data transmissions in LTE or WiMAX systems adopting different transmission protocols (i.e., immediate-first-transmission protocol or, delayed-first-transmission protocol), backoff algorithms (i.e., uniform backoff or binary exponential backoff) and retry limitations.
