    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Tomic; [2019]
    Keywords : In-flight broadband connectivity; direct air-to-ground communication; satellite air-to-ground communication; forwarding algorithm; forwarding scheme; packet loss; delay; QoS threshold; web cache; web cache hit rate; Bredbandskommunikation i flygning; direkt marknadskommunikation; satellit-till-jord-kommunikation; vidarebefordringsalgoritm; vidarebefordringsschema; paketförlust; fördröjning; QoS-tröskel; webbcache; webcache-träffhastighet;

    Abstract : Airplanes have different ways to connect to the ground, including satellite air-to-ground communication (SA2GC) and direct air-to-ground communication (DA2GC). Each connection/link offers a different varying amount of transmission capacity over flight time. READ MORE

  3. 2. Sustainable Throughput – QoE Perspective

    University essay from Blekinge Tekniska Högskola/Institutionen för kommunikationssystem

    Author : Veeravenkata Naga S Maniteja Darisipudi; [2017]
    Keywords : Mean Opinion Score; Quality of Experience; Sustainable Throughput;

    Abstract : In recent years, there has been a significant increase in the demand for streaming of high quality videos on the smart mobile phones. In order to meet the user quality requirements, it is important to maintain the end user quality while taking the resource consumption into consideration. READ MORE

  4. 3. A study of the system impact from different approaches to link adaptation in WLAN

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Kevin Perez Moreno; [2015]
    Keywords : WLAN; link adaptation; medium reuse; channel estimation;

    Abstract : The IEEE 802.11 standards define several transmission rates that can be used at the physical layer to adapt the transmission rate to channel conditions. This dynamic adaptation attempts to improve the performance in Wireless LAN (WLAN) and hence can have impact on the Quality of Service (QoS) perceived by the users. READ MORE

  5. 4. Exploiting the Direct Communication Link for Enhancing Effective Capacity Performance of Cognitive Radio Relay Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Md Abdul Matin Biswas; [2014]
    Keywords : Cognitive Radio; Quality of Service QoS ; Effective Capacity; Cooperative Relaying; Cognitive Relay Networks; Peak Interference Power Constraint; Delay QoS Constraint;

    Abstract : Nowadays, cognitive radio (CR) is a promising concept to improve the radio spectrum exploitation. CR has tremendous ability to enhance spectrum efficiency by allowing secondary users (SUs) to access licensed radio spectrum resource which is currently not being used by primary users (PUs).
