   Abstract : Cooperative intelligent transport systems (C-ITS), where vehicles cooperate by exchanging messages wirelessly to avoid, for example, hazardous road traffic situations, receive a great deal of attention throughout the world currently. Many C-ITS applications will utilize the wireless communication technology IEEE 802. READ MORE

4. 7. 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.
