  5. 3. Human factors and wireless network applications : more bits and better bits

    Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Mark Högskolan Dalarna Ekonomi och samhälle Dougherty; Angela Sasse; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human factors; Mobile multimedia; Access protocols; Computer network performance; Quality of service; Video conferencing; Computer games; Streaming video; Medium access control; Collision detection; Reliable multicast; Computer science; Datavetenskap;

    Abstract : I avhandlingen beskrivs ett hypotetiskt system som kan användas av mobila användare, bland andra taxichaufförer, som exempelvis vill följa en viktig fotbollsmatch. Flera faktorer ställer till problem: Ibland står bilen still och föraren har inget annat att tänka på än matchen. READ MORE

  6. 4. Improving user comprehension and entertainment in wireless streaming media : introducing cognitive quality of service

    Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multicast channels; Quality of Service; Cognitive QoS; Wireless LAN; Multiaccess Communication; IEEE 802.11; Displays; Mobile Communications; Video Coding; Tracking; Animation; Cognitive Psychology; Experience Design; Computer science; Datavetenskap;

    Abstract : In future mobile networks service quality might be poor. A new measure is needed to be able to assess services in terms of their effectiveness and usefulness despite their lacking visual appeal. Cognitive Quality of Service is a way to measure the effectiveness in use of a networked service. READ MORE

  7. 5. Robust Scalable Video Multicast and Performance Issues in Wireless LANs

    Author : Daniel Forsgren; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : The successful deployment of multimedia streaming services, over a multiservice IP-based heterogeneous infrastructure, requires resource-efficient, scalable and reliable network transport. This can be achieved using end-to-end methods, e.g. adaptive application-level source and channel coding. READ MORE
