  1. 11. Privacy-preserving Authentication in Participatory Sensing Systems : An attribute based authentication solution with sensor requirement enforcement.

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jose Luis Martin Navarro; [2023]
    Nyckelord :Anonymous authentication; privacy; ABS; participatory-sensing-systems; applied-cryptography; mobile-crowdsensing; Anonym autentisering; integritet; ABS; deltagande-avkänningssystem; tillämpad kryptografi; mobil-crowdsensing;

    Sammanfattning : Participatory Sensing Systems (PSS) are a type of Mobile Crowdsensing System where users voluntarily participate in contributing information. Task initiators create tasks, targeting specific data that needs to be gathered by the users’ device sensors. LÄS MER

  3. 12. Investigating Users' Quality of Experience in Mobile Cloud Games

    M1-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Markus Blomqvist; [2023]
    Nyckelord :Quality of Experience; Mobile Cloud Games; RTT; Delays; Packet Loss; Random Jitter; Bursty Jitter; Data Packets; Experiment;

    Sammanfattning : Mobile cloud gaming (MCG) is an emerging concept which aims to deliver video games on-demand to users with the use of cloud technologies. Cloud technology allows the offloading of computation from a less powerful user device or thin client to more robust cloud servers to minimize power consumption and provide additional cloud services such as storage.

  4. 13. Simulation and Testing of a MU-MIMO Beamforming System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Nyckelord :Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Sammanfattning : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. LÄS MER

    M1-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :David Lindbom; Jonathan Pettersson; [2023]
    Nyckelord :LDPC; CUDA; MSA;

    Sammanfattning : Inom dagens samhälle är de flesta mobilenheter uppkopplade till en basstation. Mycket information förväntas kunna överföras från telefonen till basstationen utan några störningar för användaren. LÄS MER

  7. 15. Outlier Robustness in Server-Assisted Collaborative SLAM : Evaluating Outlier Impact and Improving Robustness

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :José Miguel de Almeida Pedro; [2023]
    Nyckelord :SLAM; Robust Estimation; Multi-Device Algorithms; SLAM; Robust uppskattning; Algoritmer för flera enheter;

    Sammanfattning : In order to be able to perform many tasks, autonomous devices need to understand their environment and know where they are in this environment. Simultaneous Localisation and Mapping (SLAM) is a solution to this problem. LÄS MER
