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

    Författare :Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Scalable Self-Organizing Server Clusters with Quality of Service Objectives

    Författare :Constantin Adam; Rolf Stadler; Giovanni Pacifici; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Autonomic computing; self-organization; decentralized control; web services; quality of service; Telekommunikation; Telecommunication; Telekommunikation;

    Sammanfattning : Advanced architectures for cluster-based services that have been recently proposed allow for service differentiation, server overload control and high utilization of resources. These systems, however, rely on centralized functions, which limit their ability to scale and to tolerate faults. LÄS MER

  4. 3. Modeling and Tuning Security from a Quality of Service Perspective

    Författare :Stefan Lindskog; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; quality of service QoS ; tunable security; dependability; security service; data protection; security evaluation; Datavetenskap; Computer Science;

    Sammanfattning : Security has traditionally been thought of as a system or network attribute that was the result of the joint endeavors of the designer, maintainer and user, among others. Even though security can never reach a level of 100%, the aim has been to provide as much security as possible, given the boundary conditions in question. With the advent of, e.g. LÄS MER

  5. 4. Models for quality of service in heterogenoeous networks

    Författare :Rahim Rahmani; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Both streaming techniques and wireless heterogeneous networks have recently become more widely deployed. As the current streaming techniques are primarily designed for homogenous wired networks, streaming multimedia applications in heterogeneous networks can perform poorly due to wireless networks conditions and vertical handover.

  7. 5. Dynamic Management of Multi-Core Processor Resources to Improve Energy Efficiency under Quality-of-Service Constraints

    Författare :Mehrzad Nejat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Dynamic Voltage-Frequency Scaling DVFS ; Energy Efficiency; Re-configurable Core Architecture; Multi-core Resource Management; Quality-of-Service QoS ;

    Sammanfattning : With the current technology trends, the number of computers and computation demand is increasing dramatically. In addition to different economic and environmental costs at a large scale, the operational time of battery-powered devices is dependent on how efficiently the computer processors consume energy.
