According to Forbes collected data, the public cloud services market will rise in 2016 and is expected to grow to $105 billions and, in fact, Virtual Machines (VMs) are one of the most popular tools for building “Cloud” services. But in service delivery such composition of multiple components greatly complicate analysis of product quality, especially if it is about Voice over IP (VoIP) set of services,...
With the development of computer network technology and multimedia technology, real-time multimedia transmission will become increasingly important. Due to the current network bandwidth, multimedia data compression technology, and other restrictions, such as distance learning, audio and video conferencing systems, remote medical diagnosis is now basically have not been fully realized. In this paper,...
Multimedia applications such as video streaming have posed challenges over the wireless networks. A selective mapping approach was proposed in this paper to address the quality of delay-sensitive video transmitted over 802.11e EDCA wireless LAN. This cross-layer design takes into account the importance of packets and end-to-end delay requirements. Packets of high importance will be assigned to virtual...
Although the physical transmission rate increases rapidly, the quality of service (QoS) support for real-time traffic remains a challenge. 802.11 EDCA can only provide service differentiation, but not ensure the QoS as expected because of the restrained real-time traffic capacity and the uncertainty of prioritized access. This paper proposes a distributed MAC protocol called the Prioritized Access...
In recent years, Multipath TCP [1] has been extensively studied. However, it has been mainly studied for the purpose of bandwidth aggregation or smooth failover during roaming within mobile networks. Interactive real time data for the control of machines is a special case in data transmission as failure tolerance and latency are the important Quality of Service (QoS) parameters. In order to establish...
LTE is becoming the most important radio access technology for mobile Networks, providing significantly a ubiquitous broadband access. This breakthrough brings strong QoS support, especially for multimedia services which are the most used applications in telecommunication. To reach its goals, LTE needs an appropriate packet scheduling scheme. This function is fundamental and very challenging, particularly...
Carrier Aggregation (CA) has emerged as a promising technique for Long-Term Evolution Advanced (LTE-A) wireless communications to satisfy the ever-increasing bandwidth requirements. However, this technical envisagement puts forward new challenges on radio resource allocation such as serious unbalanced loads among different Component Carriers (CCs). To alleviate this problem, a novel QoS-aware resource...
In this paper, we propose a new approach for video quality control for multimedia networks. Our new approach is based on video quality measure that combines both the network quality of service (QoS) as well as the user quality of experience (QoE). The proposed approach improves the end-to-end traditional video quality control for multimedia network by including the human perception of video data,...
The LTE specification provides Quality of Service (QoS) of multimedia services with fast connectivity, high mobility, and security. However, 3GPP specifications have not defined scheduling algorithms to support real-time and non-realtime application services, this has led to the development of a variety of scheduling algorithms in the recent years. Performance is a key factor for assessing the scheduling...
One of the major challenges for real-time applications over next-generation heterogeneous access networks is the vertical handoff. Such applications require fast and efficient handover that realize service continuity and seamless mobility preserving the security and the QoS. In this paper we propose a new seamless vertical handover solution performing fast authentication while guaranteeing the QoS...
