Video services are being adopted widely in both mobile and fixed networks. For their successful deployment, the content providers are increasingly becoming interested in evaluating the performance of such traffic from the final users' perspective, that is, their Quality of Experience (QoE). For this purpose, subjective quality assessment methods are costly(More)
—Over the last couple of years, there has been an exponential increase in the number of applications accessible from various mobile handsets, including Facebook, Twitter, YouTube, etc. In particular, rich media service distribution among smart-phones and other handheld devices is becoming increasingly popular among users. In fact, the next generation(More)
One of the most important problems posed by cellular-based machine type communications is congestion. Congestion concerns all the parts of the network, both the radio and the core network impacting both the user data plane and the control plane. In this article, we address the problem of congestion in machine type communications. We propose a(More)
—Recently, many Active Queue Management (AQM) algorithms have been proposed to address performance degradations of end-to-end congestion control. However, these AQM algorithms present weaknesses for stabilizing delays in heavy loaded networks. In this paper, we describe a novel adaptive fuzzy control algorithm to improve best effort TCP/IP Networks(More)
The ISO/IEC M PEG-4 multimedia content creation, management and distribution framework is foreseen to be an important component of many forthcoming Wireless IP Multimedia services. However, current approaches for transporting MPEG-4 Elementary streams over IP networks are not optimized for wireless group communications. To address this issue we propose a(More)
To cope with the rapid increase of data traffic in mobile networks, operators are looking for efficient solutions that ensure the scalability of their systems. Decentralization of the network is one of the key solutions. With such solution, small-scale core network nodes (gateways) are locally deployed to serve the local community of users, in a(More)
Minimizing energy consumption is becoming more and more crucial in today's mobile terminals communications. Reducing its use pass necessarily by exploiting low power design techniques and by adopting novel energy-aware applications and protocols. The focus in this paper mainly concerns the Voice over IP over Wireless Local Area Network (VoWLAN) application,(More)
