  2. 11. Mobility and Multi-channel Communications in Low-power Wireless Networks

    Author : António Gonga; Mikael Johansson; Riku Jäntti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Multi-channel communications; Neighbor Discovery; MAC Protocols; Low-power Wireless Networks; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The prospect of replacing existing fixed networks with cheap, flexible and evenmobile low-power wireless network has been a strong research driver in recent years.However, many challenges still exist: reliability is hampered by unstable and burstycommunication links; the wireless medium is getting congested by an increasingnumber of wireless devices; and life-times are limited due to difficulties in developingefficient duty-cycling mechanisms.

  4. 12. Relaying for Timely and Reliable Applications in Wireless Networks

    Author : Le-Nam Hoang; Elisabeth Uhlemann; Magnus Jonsson; Anthony Ephremides; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Many emerging applications based on wireless networks involve distributed control. This implies high requirements on reliability, but also on predictable maximum delay. Further, for applications, it is vital to use off-the-shelf components, both due to cost constraints and requirements on interoperability with existing networks. READ MORE

  5. 13. Distributed Multiple Access and Service Differentiation Algorithms for Wireless Networks

    Author : Thomas Nilsson; Per-Åke Wedin; Jerry Eriksson; Lennart Bondesson; Andrzej Duda; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Local Area Networks; Medium Access Control; Quality of Service; Resource Allocation; IEEE 802.11; IEEE 802.11e; Datatransmission; Datatransmission;

    Abstract : Communicating over a wireless channel poses many unique challenges not found in wired communication because of the special characteristics of the wireless channel. The capacity in a wireless network is typically scarce as a result of the limited bandwidth and many distinct phenomenons, like attenuation and interference, that work destructively on the received signals.

  6. 14. Fundamental Aspects of Cooperative Interference Management

    Author : Hieu Do; Mikael Skoglund; Tobias Oechtering; Vincent Poor; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference management; Interference channels; Relay networks;

    Abstract : Today and future wireless networks are facing one of their greatest limiting factors:interference. This is due to the unprecedented increase in the number of connecteddevices. READ MORE

  7. 15. Design and Analysis of On-Chip Communication for Network-on-Chip Platforms

    Author : Zhonghai Lu; Axel Jantsch; Kees Goossens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Chip Communication; Network-on-Chip; System-on-Chip; Electronics; Elektronik;

    Abstract : Due to the interplay between increasing chip capacity and complex applications, System-on-Chip (SoC) development is confronted by severe challenges, such as managing deep submicron effects, scaling communication architectures and bridging the productivity gap. Network-on-Chip (NoC) has been a rapidly developed concept in recent years to tackle the crisis with focus on network-based communication. READ MORE
