An Empirical Study of the Transmission Power Setting for Bluetooth-Based Indoor Localization Mechanisms

Abstract: Nowadays, there is a great interest in developing accurate wireless indoor localization mechanisms enabling the implementation of many consumer-oriented services. Among the many proposals, wireless indoor localization mechanisms based on the Received Signal Strength Indication (RSSI) are being widely explored. Most studies have focused on the evaluation of the capabilities of different mobile device brands and wireless network technologies. Furthermore, different parameters and algorithms have been proposed as… Show more

“…In the second case, the fingerprinting method [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ], several measurements are taken at each possible position, so that there is a pre-established map of distance-RSSI values. With this approach the accuracy of the system is greater compared to the previous one, but we need an exhausted characterization of the environment.…”

“…Furthermore, a comparison with other tracking technologies might be considered. In particular, the application of the Bluetooth low energy (BLE) technology for indoor positioning purposes was investigated in [ 2 ] This technology offers the advantage of an easy implementation, because BLE functionality is embedded in widespread commercial devices. Compared to our prototype magnetic tracking system, its longer operational range allows for suitable application to many indoor scenarios.…”

“…Various techniques have been proposed to solve this problem. Several approaches are based on radio propagation, such as Ultra Wide Band [ 1 ], Bluetooth [ 2 ], and Zig-Bee [ 3 ] technologies. Alternative techniques are based on the propagation of acoustic waves, such as the ultrasound techniques proposed in [ 4 , 5 ].…”

“…However, the location of people or object in the network is the basic information for communication. Current wireless localization technologies include GPS-based [Wang, Lu, Wang et al (2017)], infrared-based [Park, Cho, Kim et al (2014)], Bluetooth-based [Castillo-Cara, Lovón-Melgarejo, Bravo-Rocca et al (2017)], signal transmission, the nodes are distributed unevenly, which will result in A* B* A* B* dh . Therefore, we can intuitively understand that if the nodes in the network are evenly distributed, the Euclidean distance between pairs of nodes is proportional to the hop count; conversely, the proportional relationship between the Euclidean distance and the hop count no longer holds.…”
