國際電信聯盟 International Telecommunication Union, ITU) 於2005 年所發布的報告中正式提出物聯網The Internet of Things (IOT)的概念，在現今網路發達的世代，除了人與人可以透過網際網路聯繫，物件與物件之間亦可以透過網路環境來進行聯繫。物聯網是一種互動式傳輸平台可用於連結智慧型裝置，Internet Engineering Task Force (IETF)針對物聯網所提出的Constrained Application Protocol (CoAP)協定被視為Machine-To-Machine (M2M)通信應用的關鍵需求。它為現有的網路環境提供了低成本、低功耗的網路服務，促進了智能家電與網路的結合。本文應用CoAP於教學環境，並比較CoAP協定與HTTP協定在傳輸效率和功率消耗上的優勢。

The development and applications of smart home networks has been promoted by Internet of Things. The Constrained Application Protocol (CoAP) is regarded as the key protocol for machine-to-machine communication. It provides constrained environments with very low overhead and low power consumption web service and integrate smart objects with the web. It describes CoAP and the differences with HTTP in performance. At last, it reports the results of the experiment showing the benefits of CoAP in teaching and transmission efficiency compared to HTTP in constrained environments.
