   Sammanfattning : How should we understand the relationship between information and communication technology (ICT) and sustainability? Generally, it is assumed that while ICT products contribute to many environmental and social problems as they are produced and disposed of, the potential of using ICT to achieve a more sustainable society is immense. However, despite the fact that such a discourse is favored not only in the industrial but also in the political and academic spheres, we have yet to see this presumed sustainability-related potential of ICT fully exploited.

5. 19. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis

   Författare :Ali Özyagci; Jens Zander; Alexandre Proutiere; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Game theory; Multichannel random access; Bayesian game; Nash equilibrium Heterogeneous channels; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER

7. 20. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

   Författare :Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
