  1. 21. Wireless Channel Prediction with Location Uncertainty

    Författare :Srikar Muppirisetty; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Spatial wireless channel prediction is important for future wireless networks, andin particular for anticipatory networks to perform proactive resource allocationat different layers of the protocol stack. In this thesis, we study location-awarechannel prediction with uncertainty in location information and understand its utilization to enhance the communication capabilities in wireless networks.

  3. 22. Geographic Routing in Intermittently-connected Mobile Ad Hoc Networks : Algorithms and Performance Models

    Författare :Erik Kuiper; Simin Nadjm-Tehrani; Di Yuan; Mats Ekman; Timothy Brown; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Communication is a key enabler for cooperation. Thus to support efficient communication humanity has continuously strived to improve the communication infrastructure. This infrastructure has evolved from heralds and ridden couriers to a digital telecommunication infrastructures based on electrical wires, optical fibers and radio links. LÄS MER

  4. 23. Telecom Networks Virtualization : Overcoming the Latency Challenge

    Författare :Dejene Boru Oljira; Anna Brunstrom; Karl-Johan Grinnemo; Javid Taheri; Bengt Ahlgren; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NFV; Telecom networks virtualization; latency; virtualization; cloud computing; network congestion; QoS; Computer Science; Datavetenskap;

    Sammanfattning : Telecom service providers are adopting a Network Functions Virtualization (NFV) based service delivery model, in response to the unprecedented traffic growth and an increasing customers demand for new high-quality network services. In NFV, telecom network functions are virtualized and run on top of commodity servers. LÄS MER

  5. 24. Lightweight Persistent Storage for Industrial Applications

    Författare :Zeinab Bakhshi; Hans Hansson; Guillermo Rodriguez-Navas; Fredrik Asplund; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Clouds are large computer centers that offer remote access to computing and storage resources, making them popular for business and web applications. They are now being considered for use in safety-critical applications such as factories, but lack sufficient time predictability, which makes it challenging to use them in these time-sensitive applications.

  7. 25. Synchronous and Concurrent Transmissions for Consensus in Low-Power Wireless

    Författare :Beshr Al Nahas; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Consesnsus; IoT; IIoT; Capture Effect; Distributed Computing; Wireless Networks; Sensing; TSCH; Bluetooth; Industrial Internet of Things; WSN; Concurrent Transmissions;

    Sammanfattning : With the emergence of the Internet of Things, autonomous vehicles and the Industry 4.0, the need for dependable yet adaptive network protocols is arising. Many of these applications build their operations on distributed consensus. For example, UAVs agree on maneuvers to execute, and industrial systems agree on set-points for actuators. LÄS MER
