  1. 36. Internet Access and QoS in Ad Hoc Networks

    Författare :Ali Hamidian; Lunds universitet; []
    Nyckelord :ad hoc networks; QoS; IEEE 802.11e; MANET; ad hoc routing; distributed resource reservation; Wireless computer communication; IEEE 802.11; ad hoc; mobile ad hoc networks; EDCA; AODV; distributed QoS;

    Sammanfattning : It is likely that the increased popularity of wireless local area networks (WLANs) together with the continuous technological advances in wireless communication, also increase the interest for ad hoc networks. An ad hoc network is a wireless, autonomous, infrastructure-less network composed of stations that communicate with each other directly in a peer-to-peer fashion. LÄS MER

  3. 37. Ungdomars virtuella rörlighet. Användningen av dator, internet och mobiltelefon i ett geografiskt perspektiv

    Författare :Eva Thulin; Göteborgs universitet; []
    Nyckelord :ICT use; Internet use; young people; everyday life; virtual mobility;

    Sammanfattning : This study explores how urban young people fit the use of information and communication technologies (ICT) into their everyday lives. Their virtual mobility may be lasting and have long-term effects on socio-spatial structures. LÄS MER

  4. 38. Towards Quality of Experience for Industrial Internet of Things

    Författare :Dimitar Minovski; Christer Åhlund; Fiedler Markus; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; IoT; AI; ML; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : Today’s research on Quality of Experience (QoE) mainly addresses multimedia services, where the end-users' subjective perception is the prime factor of determining the QoE. With the introduction of the Internet of Things (IoT), there is a need for new ways of evaluating the QoE. LÄS MER

  5. 39. Geographic information in Internet related technologies

    Författare :Christian Lundberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : The purpose of this thesis is to describe and analyse some of the possibilities and problems associated with the current and future Internet GIS. The term Internet GIS is here defined as geographical information (GI) services made available via the Internet. LÄS MER

  7. 40. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

    Författare :Sathyaveer Prasad; Peter Händel; Claes Beckman; Jan Carlsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator; Telecommunication; Telekommunikation;

    Sammanfattning : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. LÄS MER
