5. 8. Smart Cooperation with Network Coding in Hierarchical Wireless Networks

   Author : Nan Li; Lars Kildehöj Rasmussen; Daniel Lucani; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communications; Hierarchical networks; 5G; Cognitive radio; Internet of Things; Cooperative communications; Spectrum sharing; Network coding; Optimization; Performance analysis.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : To achieve more dynamic, efficient and intelligent use of the scarce wireless spectrum resource, the concept of cooperation has been formalized into several hierarchical network models in future mobile networks. Cooperative communications, such as relaying, can potentially increase communication efficiency and spectrum utilization due to the broadcast nature of wireless networks, and may lead to a better support for diverse communication modes with flexible spectrum sharing.

6. 9. Improving user comprehension and entertainment in wireless streaming media : introducing cognitive quality of service

   Author : Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multicast channels; Quality of Service; Cognitive QoS; Wireless LAN; Multiaccess Communication; IEEE 802.11; Displays; Mobile Communications; Video Coding; Tracking; Animation; Cognitive Psychology; Experience Design; Computer science; Datavetenskap;

   Abstract : In future mobile networks service quality might be poor. A new measure is needed to be able to assess services in terms of their effectiveness and usefulness despite their lacking visual appeal. Cognitive Quality of Service is a way to measure the effectiveness in use of a networked service. READ MORE

7. 10. Machine Learning for Wireless Link Adaptation : Supervised and Reinforcement Learning Theory and Algorithms

   Author : Vidit Saxena; Joakim Jaldén; Mats Bengtsson; Hugo Tullberg; Jakob Hoydis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Communications; Reinforcement Learning; Multi-Armed Bandits; Thompson Sampling; Convex Optimization; Deep Learning; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Wireless data communication is a complex phenomenon. Wireless links encounter random, time-varying, channel effects that are challenging to predict and compensate. Hence, to optimally utilize the channel, wireless links adapt the data transmission parameters in real time. READ MORE
