    Sammanfattning : Large-scale deployment of IEEE 802.11 wireless LANs (WLANs) remains a significant challenge. Many access points (APs) must be deployed and interconnected without a-priori knowledge of the demand. We consider that the deployment should be iterative, as follows. LÄS MER

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

    Författare :Nan Li; Lars Kildehöj Rasmussen; Daniel Lucani; KTH; []
    Nyckelord :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;

    Sammanfattning : 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.

  7. 25. Utility-based Optimisation of Resource Allocation for Wireless Networks

    Författare :Calin Curescu; Simin Nadjm-Tehrani; Linköpings universitet; []
    Nyckelord :wireless networks; QoS; utility price-based bandwidth; allocation optimisation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : From providing only voice communications, wireless networks aim to provide a wide range of services in which soft real-time, high priority critical data, and best effort connections seamlessly integrate. Some of these applications and services have firm resource requirements in order to function properly (e.g. LÄS MER
