Dense Small Cell networks are considered the most effective way to cope with the exponential increase in mobile traffic demand expected for the upcoming years and are one of the foundations of the future 5G. However, novel architectures are required to enable cost-efficient deployments of very dense outdoor Small Cell networks, complementing the coverage layer provided by macro-cells. In this regard,...
As the rapid growth of Wireless Local Area Network (WLAN), the densities of both Access Points (APs) and clients have dramatically increased. In the dense and crowded WLANs, the challenges of load balance become non-negligible due to the problems raised by traditional AP selection mechanism based on signal strength. To address this issue, many existing works consider the load metrics and conduct dynamic...
Our work in this paper presents a prediction of quality of experience based on full reference parametric (SSIM, VQM) and application metrics (resolution, bit rate, frame rate) in SDN networks. First, we used DCR (Degradation Category Rating) as subjective method to build the training model and validation, this method is based on not only the quality of received video but also the original video but...
Adaptive video streaming providers take advantage of the HTTP protocol to deliver video contents to the applications of the end-users. Although, these applications use bitrate adaptation to adjust video resolution to network user conditions, this mechanism is used to improve fairness. Jain's algorithm has been employed to determine the increase of the Quality of Experience (QoE) of end-users. In wireless...
The need for more efficient transmission of video stream over the network has become more exigent due to the use of video in several domains(video conference, VOD, etc). The video quality is much affected because of delay, packet loss, etc in the network which degrades the user's perceptions. In this paper, we introduce some of objective metrics (network parameters and encoding video parameters) of...
In today's world, video streaming rose above all other types of traffic. In fact, providing this service with a high quality presents the most challenging task among the advancements in networking technologies. Researchers are trying to help creating a more efficient network where congestion, broadband limitations and skyrocketing number of users present ever-diminishing obstacles. When it comes to...
