  2. 1. Autonomic wireless networking

    Author : Héctor Luis Velayos Muñoz; Gunnar Karlsson; George Polyzos; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical engineering; wireless LAN; autonomic communications; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : 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. READ MORE

  4. 2. Revenue Maximization in Resource Allocation : Applications in Wireless Communication Networks

    Author : Nilo Casimiro Ericsson; Anders Ahlén; Mikael Sternad; Jens Zander; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; wireless; resource; scheduling; revenue; admission control; service level control; service level agreement; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

    Abstract : Revenue maximization for network operators is considered as a criterion for resource allocation in wireless cellular networks. A business model encompassing service level agreements between network operators and service providers is presented. READ MORE

  5. 3. Broadband Wireless OFDM Systems

    Author : Maxime Flament; Chalmers University of Technology; []
    Keywords : channel model; 4th Generation Wireless 4GW ; shadowing; MMIC; WLAN; scenarios; mobile data; OFDM; turbo codes; propagation; license-exempt bands; coding; 60 GHz channel; broadband wireless; interference; Virtual Cellular Network VCN ; front-end;

    Abstract : While the readiness of the telecommunication market and the users' need for broadband mobile data are not currently noticeable, a set of presented megatrends and scenarios suggest that broadband mobile data access will develop quickly in the next ten years. Identification of the potential frequency bands offering cheap and trouble-free wireless infrastructure is therefore an important step towards the definition of new air interfaces. READ MORE

  6. 4. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

    Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

    Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE

  7. 5. Design Space Exploration of Wireless Multihop Networks

    Author : Urban Bilstrup; Bertil Svensson; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multihop networks; wireless sensor networks; Ad hoc networks; Design space; Wireless embedded networks; Packet radio networks;

    Abstract : This thesis explores the feasible design space of wireless multihop networks and identifies fundamental design parameters. In the process of exploring it is important to ignore all details and instead take a holistic view. READ MORE
