1. 11. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

   Författare :Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

   Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER

3. 12. Live Mobile Video Interaction : Inventing and investigating technology, formats and applications

   Författare :Mudassar Ahmad Mughal; Oskar Juhlin; Gina Venolia; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human computer interaction; liveness; live; ambient video; mobile webcasting; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : The convergence of inexpensive video-enabled mobile phones, high-speed mobile data networks and ubiquitous sensing devices opens up a new design space called “live mobile video interaction”. It gives rise to a new genre of applications concerning live mobile video production, which can be seen as an instance of the said space. LÄS MER

4. 13. Coping with Misbehavior in Mobile Ad-hoc Networks

   Författare :Sonja Buchegger; Jean-Yves Le Boudec; EPFL; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mobile ad-hoc networks; incentives; cooperation; reputation systems; Bayes; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : n this work, we address the question of how to enable a system to operate despite the presence of misbehavior. Specifically, in a mobile ad-hoc network, how can we keep the network functional for normal nodes when other nodes do not route and forward correctly? Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad-hoc networks. LÄS MER
