Recently, Vehicular Ad-hoc Network (VANET) has been drawing lots of attentions from many researchers. It is considered as an important future network for Intelligent Transportation Systems (ITS). Meanwhile, the cloud network has been gradually accepted by more and more customers as a flexible storage and computing facility. In this paper, we propose a novel communication system to integrate vehicular...
Availability is an important non-functional requirement for carrier grade services. Cloud computing is gaining in popularity but availability remains one of its main challenges in order to convince carrier grade service providers to migrate to the cloud. Several solutions, including Pacemaker/Corosync, have been proposed for managing the availability of cloud systems. On the other hand, OpenSAF, an...
The sovereignty of cloud-deployed media applications and services is improbable to be disrupted in the foreseeable future. This paper aims to provide an overview of the most essential technologies utilized by this constantly evolving cloud ecosystem, identify the design principles of a media-aware cloud and present an architectural position based on the research conclusions. An end-to-end quality-aware...
Recent studies about the use of cloud platforms indicate that more than three-fourths of healthcare institutions apply these technologies in their daily lives. However, in most cases the cloud is based on “Infrastructure as a Service”, instead of developing new applications using the benefits that can bring us this type of technology. For these reasons, this paper shows a private cloud-based system...
In this demonstration we will show the prospects of dynamic cloud service placement. A cloud service is implemented that manages real-time video streaming and real-time control commands for a remote controlled drone. The requirements for this cloud service are groundbreaking because the image transfer and the control commands should be transmitted in real time that the drone can be controlled smoothly...
We propose new architectures for collaborative video services using software defined networks (SDN) and cloud computing technologies. In the proposed architectures, the video service provider (VSP) is configured as a cloud service. The network service provider (NSP) employs SDN as a cloud service, consisting of a controller cloud and multiple edge network clouds. The proposed centralized and distributed...
Video transcoding is the process of converting a video to the format supported by the viewer's device. Video transcoding requires a huge storage and computational resources, thus, many video stream providers choose to carry it out on the cloud. Video streaming providers generally need to prepare several formats of the same video (termed pre-transcoding) and stream the appropriate format to the viewer...
Video streaming is one of the most popular and highest bandwidth consumers within the Internet today. Cloud's elastic and pay-per-use model offers viable solution to varying demands of heterogeneous viewers for large-scale video providers. Video providers are heavily exploiting cloud's elastic nature to cater the scalability and heterogeneity of video steaming related tasks. For instance, Netflix...
We have developed a prototype for a cost-aware, cloud-based content delivery network (CDN) suitable for a federated cloud scenario. The virtual CDN controller spawns and releases virtual caching proxies according to variations in user demand. A cost-based heuristic algorithm is used for selecting data centers where proxies are spawned. The functionality and performance of our virtual CDN prototype...
Video surveillance technology is a crucial element of every person's life in the modern era — an element that is concerned with the safeguarding of individuals as well as finding criminals. An effective mechanism in existing video surveillance systems is cloud-based IPTV (Internet Protocol Television) technology, which is becoming increasingly popular. In this paper, we aim to design and develop a...
The 4G standard Long Term Evolution-Advanced (LTE-A) has been deployed in many countries. Now, technology is evolving towards the 5G standard since it is expecting to start its service in 2020. The 5G cellular networks will mainly contain in cloud computing and primarily Quality of Service (QoS) parameters (e.g. delay, loss rate, etc.) influence the cloud network performance. The impact of user perceived...
The benefits of transcoding make it possible an incompatible or obsolete contents to be run at any device in a modern format. Nowadays, it is a common way to transcode contents to another format, different bitrates or qualities. As there are some limitations on the source computer which is like thin client with very low H/W specification, it is preferably recommended to be processed on the cloud environment...
To improve the quality of experience of video streaming services, content providers are challenged by the need to prepare videos at different quality levels appropriate to the network infrastructure and device hardware specification. Distributed video transcoding in the cloud has received many research attentions to address this challenge. Such a cloud-based solution segments a video into multiple...
Nowadays, there are several open-source solutions for building private, public and even hybrid clouds such as Eucalyptus, Apache Cloud Stack and Open Stack. KVM is one of the supported hypervisors for these cloud platforms. Different KVM configurations are being supplied by these platforms and, in some cases, a subset of CPU features are being presented to guest systems, providing a basic abstraction...
With the development of cloud computing, datacenter already plays increasingly important role in improving the multimedia user Quality of Experience (QoE). The resource allocation strategy, namely the virtual machines (VMs) allocation strategy, is a major research direction for cloud computing technology. In this paper, we introduce the definition of near-client-datacenter for virtual machines, which...
Mobile cloud gaming provides a whole new service model for the video game industry to overcome the intrinsic restrictions of mobile devices and piracy issues. However, the diversity of end-user devices and frequent changes in network quality of service and cloud responses result in unstable Quality of Experience (QoE) for game players. A cognitive cloud gaming platform, which could overcome the above...
Mobile cloud-based video gaming (MCVG) is an emerging trend in moving the online entertainment industry into the cloud era. In MCVG, the game engines are hosted in the cloud, and the rendered gaming videos are transmitted over wireless networks to the mobile devices. In reverse, game players' interactions on screens are sent to the cloud server over the same networks. How to compress and transmit...
This paper discusses the progress in the management interface and access to AVIP (Audiovisual technology over IP) of UNED (National University of Distance Education). The new Website ensures more accessible and easier access to services. This Site is focused on the Virtual Classroom Videoconferencing, Virtual Classroom Webconferencing and Digital repository (Campus Channel).
