本論文針對以低速低耗能為目標的IEEE 802.11ah 進行模擬分析，由於目前IEEE 802.11ah部分規範尚未定案，因此本論文針對現有的規範去研究並模擬出在Non-TIM模式之下的能耗評估分析。論文內容以802.11ah省電模式中的Non-TIM Implicit TWT為主軸，詳細介紹Implicit TWT的運作方式以及相關數值。模擬程式以C++做出802.11 Legacy並驗證正確後加入傳送流量分佈、Target Wake Time與Channel Model來完成IEEE 802.11ah Non-TIM的系統。最後介紹完成後的模擬程式在不同應用之下（農業監控、智慧儀表以及工業自動化）的數據變化（耗電量、TWT長度及Packet Drop Rate等數據）來完成本文的結論。

The main purpose of this thesis is aimed at the simulation analysis of IEEE 802.11ah with low speed and low energy consumption. Since part of IEEE 802.11ah specification has not been finalized yet, therefore, this paper focused on studying existing specifications and simulates the energy consumption evaluation under Non-TIM mode. The content of the paper is based on Non-TIM Implicit TWT in the 802.11ah power saving mode, describing the operation mode and related values of the Implicit TWT in details. The simulation program uses 802.11 Legacy in C++, verifies its correctness and then joins the Traffic model, Target Wake Time and Channel to complete the 802.11ah Non-TIM system. Finally, the conclusions of this paper are made by the data change (Power Consumption, TWT Length and Packet Drop Rate) of the complete simulation program under different applications such as Agricultural monitoring, Smart metering and Industrial automation.
