    • openAccess   Influence of Measured Radio Map Interpolation on Indoor Positioning Algorithms 

      Bravenec, Tomáš; Gould, Michael; Fryza, Tomas; Torres-Sospedra, Joaquín IEEE (2023-07-24)
      Indoor positioning and navigation increasingly have become popular, and there are many different approaches, using different technologies. In nearly all of the approaches, the locational accuracy depends on signal propagation ...

    • openAccess   Scalable and Efficient Clustering for Fingerprint-Based Positioning 

      Torres-Sospedra, Joaquín; Quezada Gaibor, Darwin; Nurmi, Jari; Koucheryavy, Yevgeni; Lohan, Elena Simona; Huerta, Joaquin IEEE (2023)
      Abstract: Indoor positioning based on IEEE 802.11 wireless LAN (Wi-Fi) fingerprinting needs a reference data set, also known as a radio map, in order to match the incoming fingerprint in the operational phase with the ...

    • closedAccess   Security and Reliability of Room Occupancy Detection Using Probe Requests in Smart Buildings 

      Fryza, Tomas; Bravenec, Tomáš; Kohl, Zdenek IEEE (2023-04-19)
      We present new approaches for determining occupancy in smart building management systems. The solutions can be applied dually, in civil and military areas, not only for economic management but also in crisis situations ...
