  1. 16. Dynamic configuration of Bluetooth mesh : A master thesis in electrical engineering

    University essay from Uppsala universitet/Signaler och system

    Author : August Fricking; [2022]
    Keywords : Bluetooth; Bluetooth mesh; BLE; BLE mesh; mesh networks; nRF52840; nRF52832; Dynamic configuration; adoptive configuration; mesh automation;

    Abstract : When choosing what IoT protocol to use today, there are lots of choices. If a mesh type network is chosen, Bluetooth mesh might be a possible candidate. Bluetooth mesh without correctly configured parameters can however suffer from congestion and packet loss if the network is very dense or consists of many nodes. READ MORE

  3. 17. Analysis of radio surveillance in search of missing persons - An empirical study of Bluetooth Low Energy and Wi-Fi characteristics

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Mikael Fredriksson; [2022]
    Keywords : Search and rescue; Wi-Fi; Bluetooth Low Energy; Wi-Fi probes; Bluetooth Low Energy advertisements; wireless sniffing; smartphones; antenna directivity;

    Abstract : Development of technical and methodological support has been identified as a key area for future research and development within the search and rescue (SAR) of missing persons in Sweden. Previous studies have demonstrated the feasibility of using Wi-Fi signals to locate a missing person, and also developed hardware and software for SAR systems based around Unmanned Aerial Vehicles (UAV).

  4. 18. Identifying Bluetooth Low Energy Devices via Physical-Layer Hardware Impairments

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Daniel Nilsson; [2022]
    Keywords : ;

    Abstract : It is desirable to be able to distinguish between Bluetooth Low Energy (BLE) devices purely based on individual hardware imperfections because such imperfections are often prohibitly expensive to imitate. Other works have been done on this topic in the past, which utilized signal transients requiring a multi-GHz sampling rate recorded with costly special equipment to be satisfactorily captured.

  5. 19. Populating a Database to be used with an Indoor Positioning System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Maria Halvarsson; Jinglan Qin; [2022]
    Keywords : Indoor positioning system; Bluetooth Low Energy; Relational database; AWS cloud services; Indoor asset tracking; Indoor navigation; Indoor localization; Database design; Inomhuspositioneringssystem; Bluetooth Low Energy; Relationsdatabas; AWS molntjänster; Tillgångsspårning; Inomhusnavigering; Inomhuslokalisering; Databasdesign;

    Abstract : Indoor Positioning System (IPS) are becoming more common in many areas such as retail, warehouses, smart facilities, and manufacturing.In recent years, Bluetooth Low Energy (BLE)-based IPS has become increasingly popular due to its low cost and low energy consumption. One of the more recent updates, Bluetooth 5. READ MORE

  6. 20. Energy comparison of wireless data transfer in an energy critical driven system : Digitizing analog meters for the world of IoT - An energy study in a concrete environment

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Simon Kantis; Eric Magnusson; [2022]
    Keywords : Internet of Things; Energy consumption; WiFi; Bluetooth Low Energy; Digitization of analog meters; Transmission power; TCP; UDP;

    Abstract : Digitizing analog meters into the IoT where meters can be read remotely is a solution which is both environmentally and economically beneficial. This study investigate show energy critical systems can gain a longer lifespan by optimizing their energy consumption. READ MORE
