  2. 6. Robust Multimedia Communications over Packet Networks

    Author : Guoqiang Zhang; W. Bastiaan Kleijn; Vinay Vaishampayan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. READ MORE

  4. 7. Studies of heterogeneous packet switched networks

    Author : Andreas Jonsson; []
    Keywords : ;

    Abstract : Internet is a packet switched heterogeneous network. Much research can be done in order to learn about the properties of and extend the capabilities of the Internet. In this thesis three studies around this topic are presented. READ MORE

  5. 8. Quality issues in Internet packet forwarding

    Author : Ulf Bodin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Abstract : This thesis addresses quality issues in Internet Protocol (IP) packet forwarding. In IP networks, queue mechanisms and scheduling can be used to construct multiple forwarding behaviors. Thereby, both relative and independent services can be offered to Internet users. Independent services offer forwarding qualities known beforehand. READ MORE

  6. 9. Convolutional Codes for Wireless Packet Data Systems

    Author : Sorour Falahati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tailbiting coding; rate compatible punctured convolutional codes; adaptive modulation system; hybrid type-II ARQ; Rayleigh fading.;

    Abstract : Automatic Repeat reQuest (ARQ) schemes can guarantee an almost error freereception strongly required in data communications. Hybrid type-II ARQschemes are supplied with channel coding to further improve the performance.In these schemes, error correction is performed adaptively which makesthem favorable for applications in time varying channels.

  7. 10. Stochastic Modeling and Simulation of the TCP protocol

    Author : Jörgen Olsén; Ingemar Kaj; Joachim Charzinski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; TCP; flow-control; network simulator; ns-2; stochastic modeling; throughput; packet loss rate; fixed-point method; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Abstract : The success of the current Internet relies to a large extent on a cooperation between the users and the network. The network signals its current state to the users by marking or dropping packets. The users then strive to maximize the sending rate without causing network congestion. READ MORE
