  1. 16. BitTorrent Traffic Measurements and Models

    Författare :David Erman; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Peer-to-peer; traffic measurements; traffic modelling;

    Sammanfattning : The Internet has experienced two major revolutions. The first was the emergence of the World Wide Web, which catapulted the Internet from being a scientific and academic network to becoming part of the societal infrastructure. The second revolution was the appearance of the Peer-to-Peer (P2P) applications, spear-headed by Napster. LÄS MER

  3. 17. On the Performance Assessment of Advanced Cognitive Radio Networks

    Författare :Thi My Chinh Chu; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio Networks; Queueing Analysis; Cooperative Communications; Multiple-Input Multiple-Output MIMO ; Adaptive Modulation and Coding; Hybrid Interweave-Underlay Spectrum Access;

    Sammanfattning : Due to the rapid development of wireless communications together with the inflexibility of the current spectrum allocation policy, radio spectrum becomes more and more exhausted. One of the critical challenges of wireless communication systems is to efficiently utilize the limited frequency resources to be able to support the growing demand of high data rate wireless services.

  7. 20. Methods and models for safety benefit assessment of advanced driver assistance systems in car-to-cyclist conflicts

    Författare :Jordanka Kovaceva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; overtaking manoeuvres; cyclist; safety benefit; naturalistic data;

    Sammanfattning : To help drivers avoid or mitigate the severity of crashes, advanced driver assistance systems (ADAS) can be designed to provide warnings or interventions. Prospective safety assessment of ADAS is important to quantify and optimise their safety benefit. Such safety assessment methods include, for example, virtual simulations and test-track testing.
