4. 7. Dynamic Resource Provisioning and Survivability Strategies in Optical Networks

   Author : Jawwad Ahmed; Lena Wosinska; Andrea Fumagalli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical networks; passive optical networks; wavelength; routing; Survivability; protection; restoration; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Optical networks based on Wavelength Division Multiplexing (WDM) technology show many clear benefits in terms of high capacity, flexibility and low power consumption. All these benefits make WDM networks the preferred choice for today’s and future transports solutions which are strongly driven by a plethora of emerging online services. READ MORE

5. 8. Spectrum Sensing for Dynamic Spectrum Access in Cognitive Radio

   Author : Inna Valieva; Dag Stranneby; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Abstract. The number of mobile devices is constantly growing, and the exclusivestatic spectrum allocation approach is leading to the spectrum scarcity problem whensome of the licensed bands are heavily occupied and others are nearly unused.Spectrum sharing and opportunistic spectrum access allow achieving more efficientspectrum utilization.

7. 10. Relaying Protocols for Wireless Networks

   Author : Majid Nasiri Khormuji; Erik G. Larsson; Christian Ibars; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; The relay channel; constellation rearrangement; decode-and-forward; resource allocation; Telecommunication theory; Telekommunikationsteori;

   Abstract : Motivated by current applications in multihop transmission and ad hoc networks, the classical three-node relay channel consisting of a source-destination pair and a relay has received significant attention. One of the crucial aspects of the relay channel is the design of proper relaying protocols, i.e. READ MORE
