2. 1. Improving user comprehension and entertainment in wireless streaming media : introducing cognitive quality of service

   Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multicast channels; Quality of Service; Cognitive QoS; Wireless LAN; Multiaccess Communication; IEEE 802.11; Displays; Mobile Communications; Video Coding; Tracking; Animation; Cognitive Psychology; Experience Design; Computer science; Datavetenskap;

   Abstract : In future mobile networks service quality might be poor. A new measure is needed to be able to assess services in terms of their effectiveness and usefulness despite their lacking visual appeal. Cognitive Quality of Service is a way to measure the effectiveness in use of a networked service. READ MORE

4. 2. Internet Video Transmission

   Author : György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
   Keywords : 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.

5. 3. Cooperative Strategies in Multi-Terminal Wireless Relay Networks

   Author : Jinfeng Du; Mikael Skoglund; Ming Xiao; Lizhong Zheng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cooperative communication; relay; network coding; network information theory; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Smart phones and tablet computers have greatly boosted the demand for services via wireless access points, keeping constant pressure on the network providers to deliver vast amounts of data over the wireless infrastructure. To enlarge coverage and enhance throughput, relaying has been adopted in the new generation of wireless communication systems, such as in the Long-Term Evolution Advanced standard,  and will continue to play an important role in the next generation wireless infrastructure.

6. 4. Analysis and Design of Rateless Codes

   Author : Iqbal Hussain; Lars Kildehøj Rasmussen; Petar Popovski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The invention of turbo codes and the re-discovery of sparse graph codes constitute a milestone in error-correction codes designed for communication and storage systems. Sparse graph codes such as low-density parity-check codes can offer a performance that approaches the previously elusive Shannon capacity with reasonable practical computational complexity.

7. 5. Fiber-Optic Interconnections in High-Performance Real-Time Computer Systems

   Author : Magnus Jonsson; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber-optic communication; Real-time communication; Computer engineering; Datorteknik;

   Abstract : Future parallel computer systems for embedded real-time applications,where each node in itself can be a parallel computer, are predicted to havevery high bandwidth demands on the interconnection network. Otherimportant properties are time-deterministic latency and guarantees to meetdeadlines. READ MORE
