碩士 === 國立臺北科技大學 === 機械工程系機電整合碩士班 === 107 === Internet of Things(IoT) has grasped great attention in recent years. Each constructed buildings tend to be “intelligent” to enhance the convenience and safety of occupants. Therefore, Indoor Positioning System (IPS) using Bluetooth Low Energy (BLE) technology to construct Location Based Service(LBS) is currently becoming real and available. However, this technology exists various challenges related to the behavior of the advertising channel 37、38、39 and the multipath effect. Because of these factors, they will lead to the Received Signal Strength Indicator (RSSI) fluctuations and precision. In order to mitigate these effects, this paper presents an IPS based on BLE, that improves accuracy while reducing power consumption and costs. The main point of this technique is that using PeTacom Protocol to establish Location Based Mesh Network (LBMN) and realize interactive communication between people to objects. Simultaneously, the system integrates various sensors, algorithms, and system design to establish an IPS. The analysis of the results proves that all the proposals improve the precision of the system, which precise goes up to 1.5 m for moving in area 45m×31m for devices.
