人們想提高生活品質的想法造就了物聯網時代的來臨，如何更容易地取得想要的感測資料，以及更有效率地管理設備也成為物聯網實作的重要主題。為了管理裝置，傳統網路環境我們會對所有裝置配置名為IP的數字標籤，而鑒於IPv4數量逐漸枯竭，IPv6技術將取代之成為網路上用於識別個體的新依據。再者，物聯網設備還有另一項不可忽視的問題 - 電池耗能。環境感測器每次在充完電或更換電池之後必須工作很長一段時間，若期間能源耗盡感測服務即失去功用。在本篇論文中，我們使用了IPv6結合藍牙低功耗（Bluetooth Low Energy，縮寫為BLE）技術，讓感測器網路內設備可以相互溝通且達到低耗能的效果。同時實做出異質網路閘道器，以達成與網際網路結合的目標。並且在IPv6基礎上使用MQTT與MQTT-SN應用層協議向用戶提供推播、訂閱服務，以期達到感測器設備主動向客戶提供訂閱訊息的效果。整合以上各項技術，我們預期做出一個以IPv6作為設備辨別依據，以求管理智慧化的藍牙低功耗環境資訊蒐集系統 Due to the desire of improvement on quality of life, people are expecting to enter the new era of Internet of Things (IoT). How to obtain data from a great number of sensors and manage them effectively have become one of the important challenges we need to conquer. Because of the exhaustion of IPv4 addresses, IPv6 is designed to replace IPv4 as the new identity of devices connected to the Internet. There is another challenge for IoT – power consumption. If a battery-operated IoT device runs out of power, it will stop working. In this thesis, we combine IPv6 with Bluetooth Low Energy (BLE) to build a low-power wireless local area network. We also develop a heterogeneous gateway, which can integrate BLE device with other smart objects over either wired or wireless communications. By using Raspberry Pi 3 development boards as the BLE nodes and the gateway, on top of them we have deployed Message Queuing Telemetry Transport (MQTT) and MQTT-Sensor Network (MQTT-SN) application protocols to transport sensor data using the publish/subscribe model. We expect that many intelligent IoT applications can be built over our prototype system based on IPv6/BLE
