  1. 1. Internet Video Transmission

    Author : György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Abstract : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.

  2. 2. Traffic Control for VBR Video in Packet Switched Networks

    Author : György Dán; KTH; []
    Keywords : Traffic control; VBR video; shaping; FEC; QoS;

    Abstract : The best effort service offered by the Internet is notsatisfactory for the transmission of loss and delay sensitivedata, such as real-time voice and video. In order to provideservice guarantees at reasonably high load levels, additionalcontrol functions haveto be employed in the network. READ MORE

  3. 3. Live Streaming Performance of Peer-to-Peer Systems

    Author : Ilias Chatzidrossos; György Dán; Renato Lo Cigno; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In peer-to-peer (P2P) live streaming systems peers organize themselves in an overlay and contributewith their resources to help diffuse live content to all peers in a timely manner. The performanceof such systems is usually characterized by the delay-loss curve, which quantifies theplayback delay required for achieving a certain streaming quality, expressed as the chunk missingratio at the peers.

  4. 4. Distributed Processing of Visual Features in Wireless Sensor Networks

    Author : Emil Eriksson; György Dan; Viktória Fodor; Ioannis Andreopoulos; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

    Abstract : As digital cameras are becoming both cheaper and more advanced, they are also becoming more common both as part of hand-held and consumer devices, and as dedicated surveillance devices. The still images and videos collected by these cameras can be used as input to computer vision algorithms for performing tracking, scene understanding, navigation, etc. READ MORE

  5. 5. Decentralized Algorithms for Resource Allocation in Mobile Cloud Computing Systems

    Author : Sladana Josilo; György Dán; Dario Pompili; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The rapid increase in the number of mobile devices has been followed by an increase in the capabilities of mobile devices, such as the computational power, memory and battery capacity. Yet, the computational resources of individual mobile devices are still insufficient for various delay sensitive and computationally intensive applications. READ MORE
