隨著無線通訊技術快速發展，物聯網(Internet of Things, IoTs)的應用領域廣泛、且物件種類多元，如何達成物件自動配置及提升物件操控性，以降低使用者設定問題並能符合節能概念，皆為物聯網未來探討之議題。值得注意的是，基於智慧型行動裝置的可攜性、無線通訊與行動運算等優點，藉由與物聯網之相互結合，能衍生出更豐富且創新的應用服務。目前市面上所提的藍牙低功率裝置(BLE)可應用於室內定位，然而隨時隨地的知道感知位置是會非常耗電的，若數十個人戴著穿戴式裝置，則需透過額外的人力，隨時檢查電池使用狀況、幫忙充電或更換電池裝置，更甚者乃至於一百個、一千個穿戴式裝置，將會是個很可觀的工程。本研究所探討之議題在於感知位置的精確度和廣播頻率(Advertising interval time)耗電之間的取捨，分析物聯網BLE節點之資料特性與定位應用，並依照定位結果去動態調整資料的處理方式，進而達到BLE節點行動裝置省電之功效。因此，本研究提出一套智慧節能物聯網架構的可行方案，使用智慧型行動裝置作為物聯網之中間層，並將連線模組與掃描模組擷取資訊建立於中間層內，隨著應用程式啟動，物聯網裝置資訊將透過中間層，待掃描模組擷取資訊後，資訊將交由後端伺服器做定位的功能，定位功能是一直持續在運作的並根據實際執行經驗和定位的準確性，動態的調整廣播間隔時間。最後，本研究提出兩項智慧節電生活應用，分別為遊樂園與養護中心，透過不同之應用情境進行分析，根據研究結果顯示，相較於預設的BLE節點廣播間隔時間，智慧節能物聯網架構分別節省了58.3% 與64.7%的電源消耗，故動態調整廣播間隔時間的處理方式能確實降低電源消耗，有效的延長設備的使用時間。

With the rapid development of wireless communication technology, a wide range of applications and multiple object genres of Internet of Things (IoTs), how to achieve automatic object allocation and enhance object handling to reduce user setting problems and conform to the concept of energy conservation are IoTs issues to be investigated. What is noteworthy is that smart mobile devices, with the advantages of portability, wireless communication capability and mobile computing capability, have been rapidly developed. Currently, the Bluetooth low energy (BLE) devices which performed anytime and anywhere would be very energy consuming for indoor positioning. Moreover, if ten persons are equipped with wearable devices, extra manpower would be required to check the battery usage status, help to charge batteries or replace battery devices. Even worse, if one hundred or even one thousand persons are equipped with wearable devices, the efforts required would be substantial. This study investigated the issues regarding the trade-offs between accuracy of sensor positioning and the power consumption of frequency for advertising interval time. Also, the data characteristics of BLE nodes in the IoTs network and their applications in positioning based on which the data processing method was dynamically adjusted to achieve the effect of energy conservation for the BLE nodes of the mobile device network are analyzed. This study proposed a feasible alternative for the smart energy saving IoTs framework wherein the smart mobile devices were used as the middle tier, in which information captured by connection and scanning modules was built. With the activation of the application program, the IoTs information captured by the scanning module via the middle tier, would be transmitted to a backend server to perform positioning function wherein the positioning function operates continuously. Based on the practical implementation and experience, the accuracy of positioning and advertising interval time would be dynamically adjusted. Finally, this study proposed two scenarios of smart energy conservation for amusement park and convalescent center. The experiential results suggest that, compared to the default advertising interval time of the BLE nodes, the advertising interval time achieved by the smart energy conservation IoTs framework reduces 58.3% and 64.7% of energy consumption respectively for the two examples. The proposed method with dynamically adjust advertising interval time indeed reduces power consumption and effectively extends the usage time of fully charged equipment.
