  2. 1. Reliable and deterministic network services

    Author : Florian-Daniel Otel; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; queuing delay guarantees; service curve; constraint-based routing; TCP; network security; arrival curve; network failure recovery; traffic engineering; network calculus; traffic envelope;

    Abstract : In a post Internet bubble economic environment the obvious lack of any disruptive new technologies that could give new impetus to network growth (as, for example, experienced after the appearance of the Web) lead to a trivialization of network services: Aside grass-roots, semi-subterranean applications like file sharing, entertainment content swapping and on-line gaming, it can be argued that network services are presently used in a manner not very different than a decade ago. In this respect, one of the factors that can be identified as limiting further development is the perceived lack of guarantees with regard to network services. READ MORE

  4. 2. Energy Saving vs. Performance: Trade-offs in Optical Networks

    Author : Pawel Wiatr; Paolo Monti; Josep Solé-Pareta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; optical networks; RWA; side-effects; device reliability performance; network performance; operational cost; benefits; loss; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. READ MORE

  5. 3. Channel Estimation Aspects of Reconfigurable Intelligent Surfaces

    Author : Doga Gürgünoglu; Gabor Fodor; Emil Björnson; Jaap van de Beek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable intelligent surface; channel estimation; pilot contamination; positioning; angle of arrival estimation; integrated sensing and communications; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In the sixth generation of wireless communication systems (6G), there exist multiple candidate enabling technologies that help the wireless network satisfy the ever-increasing demand for speed, coverage, reliability, and mobility. Among these technologies, reconfigurable intelligent surfaces (RISs) extend the coverage of a wireless network into dead zones, increase capacity, and facilitate integrated sensing and communications tasks by consuming very low power, thus contributing to energy efficiency as well.
