  1. 1. Efficient concurrent data structure access parallelism techniques for increasing scalability

    Författare :Adones Rukundo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; FIFO queue; parallelism; performance modelling; design framework; semantic relaxation; Data structure; multi-access; lock free; performance analysis; counter; concurrency; search tree.; stack; multi-core processor; priority queue;

    Sammanfattning : Multi-core processors have revolutionised the way data structures are designed by bringing parallelism to mainstream computing. Key to exploiting hardware parallelism available in multi-core processors are concurrent data structures. LÄS MER

  3. 2. Radio resource sharing and bearer service allocation for multi-bearer service, multi-access wireless networks

    Författare :Anders Furuskär; KTH; []
    Nyckelord :;

    Sammanfattning : Two expected characteristics of future wireless networks aresupport for multiple bearer services, which in turn enablemultiple end-user services, and the parallel use of multipleradio access technologies. This dissertation discusses radioresource management principles to improve capacity for suchmulti-bearer service, multi-access networks. LÄS MER

  4. 3. Low Latency Communication in Virtualized and Multipath Networks

    Författare :Dejene Boru Oljira; Anna Brunström; Karl-Johan Grinnemo; Javid Taheri; David Ros; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Latency; Virtualization; Cloud computing; NFV; DCTCP; MPTCP; L4S; Network measurement; Performance evaluation; Queuing; Computer Science; Datavetenskap;

    Sammanfattning : The demand from customers for high-quality and customized network services has increased. Telecom service providers have adopted a Network Functions Virtualization (NFV) based service delivery model, in response to the unprecedented traffic growth and increasing customer demand. LÄS MER

  5. 4. Resource Allocation in Multi-Antenna Communication Systems with Limited Feedback

    Författare :David Hammarwall; Björn Ottersten; David Gesbert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : The use of multiple transmit antennas is considered a key ingredient to significantly improve the spectral efficiency of wireless communication systems beyond that of currently employed systems. Transmit beamforming schemes have been proposed to exploit the spatial characteristics of multi-antenna radio channels; that is, multiple-input single-output (MISO) channels. LÄS MER

  7. 5. Performance Analysis and Optimization for Time Critical Networking

    Författare :Emmanouil Fountoulakis; Nikolaos Pappas; Vangelis Angelakis; Qi Liao; Giuseppe Durisi; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Future communication systems will be characterized by heterogeneous traffic and requirements. Time critical applications like cyberphysical systems, augmented and virtual reality, raise the need for a low-latency based network. At the same time, conventional devices requiring for high throughput will co-exist with time critical applications. LÄS MER
