近年來在節能減碳的議題下，智慧電網(Smart Grid)逐漸興起，意指升級既設的電網以更好的方法生產與配送電力，來因應不同的需求，使監視、安全、控制能源使用，以及因應任何電力需要，進而形成智慧化電力網路，使得電力系統運轉效率、供電品質與可靠性提升。而智慧電網其中的自動計量基礎設(Advanced Metering Infrastructure; AMI)，在大量佈建於網路的建立過程中，如何能以穩定的時間延遲及有效提升資料傳輸成功率來達成完整網路的建立，則成為一個重要的課題。
我們利用可見光的無線通訊傳輸解決智慧電網相關的議題，使用光的特性，來傳遞訊號，而LED的發展也使得高速的可見光無線通訊(Visible Light Communication; VLC)成為可實現的技術；在通訊協定方面，IEEE 802.15.7標準定義之可見光通訊的網路實體層與媒體存取控制副層的運作，使得智慧電網的通訊協定有明確規範可使用。
在智慧電網之家庭區域網路中，家用裝置彼此之間會互相傳遞訊息來交換能源使用情形，為了能使安全控制訊號與資料可以及時到達目的端，其中最為重要的是各類型訊號的可容忍延遲時間，若訊號無法在標準所訂定的時間內送達，其可能造成財產損失及人員的傷亡。在IEEE 802.15.7標準中，並無針對傳輸服務品質(Quality of Service; QoS)進行規範以至於無法滿足智慧電網中對通訊系統服務品質的要求。
因此，本論文將針對智慧電網家庭區域網路中的安全控制訊號及一般資料，提出智慧電網超碼框調整傳輸機制(Superframe adjustment transmission mechanism for HAN Smart gird ; SATHS)，針對不同優先權之訊號資料使用不同的傳輸方式，以達到各訊號類型與等級之規範，並提升其高優先權等級資料訊號之傳輸成功率。
為了確保此傳輸機制能滿足智慧電網的通訊服務品質要求，本論文以產能、有效產能、平均封包丟棄率以及平均傳輸延遲時間等項目來評估系統效能。
模擬結果顯示本論文所提出的SATHS機制，不僅能夠將家庭區域網路間傳輸的訊號依照美國能源局規範的訊號類別進行分類，並能同時符合標準規範中訂定的延遲時間。

In recent years, due to the issues of energy saving, the Smart Grid has become more and more important. It means to update the existing smart grid to produce and delivery electricity with appropriate method. Through this, we can reactive to various requirement of energy or electricity such as monitoring, security and control system with efficient to operation and reliable energy providing. AMI(Advanced Metering Infrastructure) is the basic of smart grid, however, AMI’s network initialization usually cost lots of time delay and energy waste because of many collisions due to the initialization in the high node density and variable network.
We can utilize the Visible Light Communication (VLC) to solve the related issue in smart grid. With the growing popularity of LED development, VLC becoming an achievable technique. In the communication protocol, IEEE 802.15.7 standard defines the physical layer of visible light communication and media access control sublayer operation, making the smart grid protocol specification been well defined.
In the smart grid Home Area Network(HAN), smart devices would transmit messages between each other to exchange appliances energy status. In order to make these security and control signals can reach the destination in time, the most important requirement is the various types of signal delay that can be tolerated. If the signal cannot reach the destination in time, it could cause property damage and personnel casualties. In the IEEE 802.15.7 standard does not defined the Quality of Service(QoS) application about smart grid.

To solve the above mentioned problems, this thesis proposes the SATHS (Superframe adjustment transmission mechanism for HAN Smart gird) mechanism. SATHS uses different transmit methods to adapt different priorities to achieve specification and improve transmission efficiency of high priority signals.
To ensure the proposed mechanism achieve the requirement of QoS, we use throughput, goodput, average frame drop ratio and average delay per frame to evaluate the system efficiency.
The simulation results show the proposed mechanism can not only classify the signal in HAN in accordance with the standard of U.S. Department of Energy but also satisfy the delay time in system.
