通訊科技的進步以及物聯網的興起，市面上出現了許多不同無線傳輸協定的設備以及感測器，例如Wifi、藍牙(Bluetooth)、LoRa等通訊協議，因為不同傳輸協定資訊整合的需要，市面上逐漸出現支援單一或多個傳輸協定的微控制器（microcontroller, MCU），而異質網路、智慧家庭相關的產品也相繼問世。本研究基於物聯網的架構研究異質網路的資料整合、應用，蒐集不同通訊協定的資訊，使感測器的資料，可經由市面上不同的網路通訊協定來傳輸資料，整合於閘道器的設計，並利用訊息佇列遙測傳輸MQTT（Message Queuing Telemetry Transport）通訊架構，讓遠端的使用者能夠即時監控與操作，本研究整合了TCP/IP (Transmission Control Protocol / Internet Protocol)以及Bluetooth協定下的低功耗藍牙BLE(Bluetooth Low Energy)以及訊息佇列遙測傳輸MQTT作為無線傳輸，使用ESP32 MCU能夠支持多種通訊協定的傳輸，再由樹莓派(Raspberry- Pi)當作異質網路閘道器，將資料整合後經由混沌系統所產生的混沌亂數、AES-CFB、SHA3-256多道程序加密後，以MQTT傳輸協定搭配混沌動態主題與使用者端進行連接，以達到資料監控時的資料安全性與方便性，同時資料會上傳至MySQL資料庫中，以便使用者回顧之前的感測紀錄。

Following advancement of communication technology and the rise of the Internet of Things, many devices and sensors with different wireless transmission protocols have appeared, such as Wifi, Bluetooth, LoRa and other communication protocols. Due to the demand for information integration of different protocols, Microcontrollers (MCUs) supporting single or multiple transmission protocols are developed, and products related to heterogeneous networks and smart homes are also proposed. Based on the architecture of the Internet of Things, this thesis aims to study the data integration and application of heterogeneous networks. By collecting data of different communication protocols, so that the sensor data can be transmitted through different network communication protocols and integrated in the gateway. Then through MQTT (Message Queuing Telemetry Transport) communication architecture, remote users can monitor and operate in real time. This research integrates TCP/IP (Transmission Control Protocol / Internet Protocol) and Bluetooth Low Energy under the Bluetooth protocol and utilize MQTT as wireless transmission. ESP32 MCUs are used to support the transmission of multiple communication protocols and then Raspberry Pi (Raspberry-Pi) is designed as a heterogeneous gateway. After encrypting the data with the chaotic random numbers, SHA3-256 and AES-CFB, the MQTT transmission protocol are combined to connect with the user end to achieve data security. At the same time, the data will be uploaded to the MySQL database so that users can review previous sensing records.
