隨著物聯網的發展，網狀網絡技術的建構對物聯網應用帶來更多樣的互通性，包括拓展傳輸範圍、降低總體無線系統功耗和提升網路的擴展性，由於手機的普及，使得藍牙在無線通信技術中佔了一席之地，然而在當今老齡化社會中，對於高齡者的生活與照護的品質相當重要，許多護理機構尋求技術支援，為了減少人力開支，以及照護員不足的情況下，室內定位系統(IPS)的需求是不可忽視的，為了能掌握高齡者的動向和健康狀態，本文利用一套位基型網狀網絡，並且使用低功耗藍牙在穿戴式裝置上建構移動定位服務(LBS)，其中搭載了三軸陀螺儀與三軸加速度計(IMU)，依照IMU的判斷與固定式感測器互動，將讀到的行為傳送至雲端並儲存紀錄，不僅可對老年人進行跌倒偵測，還可以與各種感測器，例如磁簧開關、坐墊、踏墊等的互動，通過結果的分析證明，整套系統的結合可讓資料庫記錄老年人的一天活動和行為，除了藉由網頁或手機掌握當前老年人的位置外，還能得知年長者長期的活動狀態與作息的規律;除此之外，以藍牙5.0協議設計出藍牙5.0的位基型網狀網絡，使得資料可以達到跨樓層或跨棟的互通性，並且比對藍牙4.2的網狀網絡在傳輸速度與傳輸範圍上的優勢與差別。

With the development of the Internet of Things, the construction of mesh network technology brings more interoperability to the Internet of Things applications, including expanding the transmission range, reducing the overall wireless system power consumption, and improving the scalability of the network. Makes Bluetooth occupy a place in wireless communication technology, and can control many peripheral devices through flooding or connection. And then, the quality of life and care of the elderly become a very important issue in today’s aging society. Many nursing institutions seek technical support to reduce labor costs and the shortage of caregivers cause the demand for indoor positioning systems (IPS) growing rapidly. In order to grasp the trends and realize the health status of the elderly, this article use location-based mesh networks, and use Bluetooth low energy to build on the wearable device to construct the Location Based Service (LBS). The wearable device is also equipped with an inertial motion unit (IMU) which comprises a three-axis gyroscope and a three-axis accelerometer. It interacts with the fixed sensor according to the judgment of the IMU. The information of collection is transmitted to the cloud and stored in the record. It can not only detect the fall of the elderly but also interact with various sensors, such as reed switches, seat cushions, pedal mats, etc. The analysis of the results proves that the combination of the entire system allows the database to record the activities of daily life and behaviors of the elderly. Through the web or mobile phone, the system can know the current position of the elderly but also record the long-term status activity and regularity of life of the elderly for better healthcare. Besides, our location-based mesh network uses the Bluetooth 5.0 protocol to design, so that the data can achieve inter-floor or cross-building interoperability, and compare the advantages and differences in the transmission speed and transmission range of the Bluetooth 4.2 mesh network.
