  2. 2. Behaviour of WebRTC in Non-optimal Networks

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Simon Johansson; [2018]
    Keywords : WebRTC; interference; perceived quality; online survey; audio;

    Abstract : The behaviour of WebRTC when the real-time communication with audio is done over a non-optimal network is investigated in this thesis. Different methods for collecting and analyzing data from an online survey are considered. READ MORE

  3. 3. Emulating Software-Defined Small-Cell Wireless Mesh Networks Using ns-3 and Mininet

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Marcus Pieskä; [2018]
    Keywords : software defined networking; network emulating; network simulating; wireless networks;

    Abstract : The objective of this thesis was to create a network emulator, suitable for evaluatingsolutions in a small-cell wireless mesh SDN backhaul network environment, by integratingexisting software. The most important efforts in this process have been a transparentintegration of Mininet and ns-3 at both the data and the control plane, with ns-3 servingas the front-end. READ MORE

  5. 5. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Gustav Eriksson; [2018]
    Keywords : Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

    Abstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna. READ MORE
