2. 11. Opportunistic Content Distribution : Feasibility, Design and Performance Evaluation

   Author : Ólafur Helgason; Gunnar Karlsson; Cecilia Mascolo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : Originally, the main purpose of the wired Internet was to interconnect hosts on different networks in order to allow them to communicate. Although this is still an important service, the Internet has evolved and today its predominant application is to provide its users with access to contents. READ MORE

4. 12. Distribution Preserving Quantization

   Author : Minyue Li; W. Bastiaan Kleijn; Jan Østergaard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. READ MORE

5. 13. Opportunistic Content Distribution

   Author : Ólafur Helgason; Gunnar Karlsson; Mostafa Ammar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : In recent decades, communication networks have had a profound effect on society. Wireless communication has affected our lifestyle and altered how humans communicate and the Internet has revolutionized how we access, publish and disseminate information. READ MORE

6. 14. Opportunistic Content Distribution : A System Design Approach

   Author : Sylvia Todorova Kouyoumdjieva; Gunnar Karlsson; Martin May; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. READ MORE

7. 15. Performance Analysis of Opportunistic Content Distribution via Data-Driven Mobility Modeling

   Author : Ljubica Pajevic; Viktória Fodor; Thrasyvoulos Spyropoulos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic communication; mobility; content distribution; network performance modeling; trace-collection analysis; stochastic models.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : An opportunistic network is formed by co-located mobile users in order to exchange data via direct wireless links when their devices are within transmission range, without relying on the use of fixed network infrastructure. In this thesis we investigate the capabilities of opportunistic networks and cover two main areas: data-driven modeling of user mobility and analytic performance evaluation of location-aware opportunistic content distribution.
