RESEARCH PAPER / Feb 2014
To support the influx of total network traffic fueled by the availability of new wireless devices and applications, 802.11Wi-Fi networks have seen an increase in deployment in dense environments to serve client WLAN stations. In this paper, an enhanced Transmit Power Control scheme and a new fractional Carrier Sense Multiple...
RESEARCH PAPER / Feb 2014
The ultimate goal of network resource allocation for video teleconferencing is to optimize the Quality of Experience (QoE) of the video. This paper proposes a QoE prediction scheme by considering QoE models that use the per-frame PSNR time series as the input, thus reducing the QoE prediction problem to a...
RESEARCH PAPER / Feb 2014 / mmW
This work investigates the propagation characteristics of an office building in the 60 GHz band. From reflection and scattering measurements of several painted and un-painted common building materials recorded at 60 GHz, the complex permittivity and Lambert’s Law scattering coefficient of each material are extracted. Diffraction measurements at a building...
RESEARCH PAPER / Feb 2014 / MIMO
In the underlay cognitive radio approach, secondary users (SUs) are allowed to transmit their messages as long as the negative impact on the performance of the primary user (PU) is below a certain threshold. This paper considers a MIMO underlay cognitive radio network with a single PU and multiple SUs....
