  2. 11. A Software Framework for Prioritized Spectrum Access in Heterogeneous Cognitive Radio Networks

    Author : Yong Yao; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cognitive Radio Networks; Queueing Modelling; Spectrum Decision; Fuzzy-Logic; Cellular Network; Ad-Hoc Network; Mesh Network;

    Abstract : Today, the radio spectrum is rarely fully utilized. This problem is valid in more domains, e.g., time, frequency and geographical location. READ MORE

  4. 12. Performance Guarantees for Physical Layer Authentication in Mission-Critical Communications

    Author : Henrik Forssell; Ragnar Thobaben; Stefano Tomasin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical layer authentication; mission-critical communica- tions; worst-case performance; queueing delay performance; stochastic net- work calculus; optimal attack strategies.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : As the application areas for wireless communications are expanding, we also see new security vulnerabilities arise due to the open nature of the wire- less medium. One particularly challenging problem is how to guarantee the security of emerging mission-critical communications, e.g. READ MORE

  5. 13. Measurements and Models of One-Way Transit Time in IP Routers

    Author : Doru Constantinescu; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Traffic measurements; Traffic modeling; Delay performance;

    Abstract : The main goals of this thesis are towards an understanding of the delay process in best-effort Internet for both non-congested and congested networks. A novel measurement system is reported for delay measurements in IP routers, which follows specifications of the IETF RFC 2679. READ MORE

  6. 14. Some topics in web performance analysis

    Author : Jianhua Cao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis consists of four papers on web performance analysis. In the first paper we investigate the performance of overload control through queue length for two different web server architectures. The simulation result suggests that the benefit of request prioritization is noticeable only when the capacities of the sub-systems match each other. READ MORE

  7. 15. Design and evaluation of network processor systems and forwarding applications

    Author : Jing Fu; Gunnar Karlsson; Tilman Wolf; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : During recent years, both the Internet traffic and packet transmission rates have been growing rapidly, and new Internet services such as VPNs, QoS and IPTV have emerged. To meet increasing line speed requirements and to support current and future Internet services, improvements and changes are needed in current routers both with respect to hardware architectures and forwarding applications.
