  1. 11. Cooperative and non-cooperative wireless access : Resource and infrastructure sharing regimes

    Författare :Johan Hultell; Jens Zander; Cristina Comaniciu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radio resource managment competition cooperation game theory; Telecommunication; Telekommunikation;

    Sammanfattning : Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. LÄS MER

  4. 13. A Bottom-Up Approach to Real-Time Search in Large Networks and Clouds

    Författare :Misbah Uddin; Rolf Stadler; Jürgen Schönwälder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Networked systems, such as telecom networks and cloud infrastructures, generate and hold vast amounts of conguration and operational data. The goal of this work is to make all this data available through a real-time search process named network search , which will enable new real-time management solutions. LÄS MER

  5. 14. Towards energy efficient protocols for active RFID

    Författare :Björn Nilsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RFID; active RFID; protocol; back-off; carrier sense; energy efficient; wireless networks; active tag; energy consumption; Computer engineering; Datorteknik;

    Sammanfattning : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. LÄS MER

  7. 15. Secrecy for mobile implementations of security protocols

    Författare :Pablo Giambiagi; KTH; []
    Nyckelord :;

    Sammanfattning : Mobile code technology offers interesting possibilities tothe practitioner, but also raises strong concerns aboutsecurity. One aspect of security is secrecy, the preservationof confidential information. LÄS MER
