HTTP Adaptive Streaming (HAS) has become increasingly more popular. However, the research about HTTP adaptive streaming for multi-server environments is limited. Compared with traditional single-server environments, HAS for multi-server environments is able to offer expanded bandwidth, link diversity, and reliability. However, it is a challenging issue to support the seamless playback in multi-server...
Adaptive content streaming is frequently used as an efficient and cheap solution to achieve a good quality for media streaming, in systems having light Over-the-Top architectures. The streaming system developed here makes an initial optimized server selection based on multi-criteria algorithms and then in-session media adaptation. The focus of this paper is on performance analysis (based on real-life...
Most businesses collect and store sensitive information about their work or related like project documents, audio data, video data etc. while sharing files in peer-to-peer system dynamically peer nodes can add may delete. Peer-to-Peer file sharing using P2P application architecture. Shared files will move between different nodes. P2P technology is using by popular services like Napster, Bit Torrent,...
Intensive worldwide effort is speeding up the developments in the establishment of a global surveillance network for combating pandemics of emerging infectious disease. However, there is no delivery platform available to send accurate and just-in-time disease information to reach out to the community. The public can only obtain information from the newspaper, radio or social media, which sometimes...
User-Centric work Space (UCS) service enables a personalized (user-centric) work space for a user by orchestrating local and/or remote IT resources. Instances of IT resources include file, printer, monitor, keyboards. With UCS service, a user can have his personalized and secure work environment at anywhere and anytime by storing and processing his data in secure manner without any interference from...
Modern people are concerned with healthy eating habits; however, sustaining these habits often requires vigilant self-monitoring and strong will. In a related work, a social media system was proposed that enables people to begin eating naturally meals without conscious effort. The system used the concept of expectation assimilation, that is, it converted others' evaluations of healthfulness into those...
A key feature of Cloud computing is its agility and flexibility to support the scalability needs of business solutions. Currently, the agility is only limited to the scalability of the compute, memory and storage. To improve an application's agility, we need to monitor & measure solution level metrics and associate the performance of the metrics to the business agility needs of the solution...
This paper proposes a smart, easy-deployed remote monitor system based on Android system. Different from normal monitor system, what you need to deploy the monitor system are only a camera, a PC with Linux system and an Android smart phone, which is commonly held by people. The system is based on the open-source library live555, FFmpeg and x264, thus it is readily extendable. In this system, the video...
Media streaming services are responsible for the significant increase of Internet traffic. This fact generates the need for better computing resources management in order to maintain such services always available. Cloud computing offers an elastic infrastructure that provides computing resources on demand in order to maintain such services always available. Moreover, emerging network architectures,...
The proliferation of the Internet technology has contributed to an increasing demand for streaming applications. The adaptation of multimedia streaming content according to context information is essential to supporting these applications. In this paper, we design a context-aware multimedia quality adaptation framework for smart streaming. The proposed framework seamlessly provides multimedia data...
In this paper, we present a home sleep care system to monitor function of activity measurement and sleeping position estimation via vision-based algorithms. The outcomes are integrated in a telecare middleware with a hierarchical software stack and visualized by a structural subsystem. Since smart TVs play an important role in home tele-healthcare system, we centralize and display additional sleep...
Currently commercial live video streaming systems are based either on a typical client-server or on a peer-to-peer architecture. The former outperforms in terms of stability and quality of service, provided that the system is not stretched beyond its limits, while the latter is scalable and has a much lower cost of operation with regards to the required bandwidth resources. In this paper, we propose...
With the development of cloud computing, the resource management in cloud environment and flexible adaptation of services are becoming more and more important. In this paper, we design and implement a resource management system of multimedia conference based on cloud from the perspective of service provider. Media adaptation layer and automatic deployment in management system improve resource utilization...
Management of content servers enables to lower the probability of congestion and overload situations in the network as well as dealing with such situations if they occur. Hence the overall quality of media delivery experienced by the end users is improved. In this paper we propose an integrated system for adapting the content servers that is capable of analyzing current network conditions (fault reporting)...
Today, Smart Home monitoring services have attracted much attention from both academia and industry. However, in the conventional monitoring mechanism the remote camera can not be accessed for remote monitoring anywhere and anytime. Besides, traditional approaches might have the limitation in local storage due to lack of device elasticity. In this paper, we proposed a Cloud-based monitoring framework...
In recent years, dynamic storage tiering has been proposed as one of the storage virtualization technologies. In this storage system, a volume is divided into sub-volumes, which can be migrated among different performance storage media according to the frequency of I/O operations, etc. This technology is expected to reduce the total storage media cost. But there is no method to assure a certain service...
This article proposes an agent-based real-time monitoring system for large scale peer-to-peer video streaming platforms which provides traffic, user receiving quality and system information through web-based presentation. The information is useful for helping service providers to assess the system performance as well as the quality of the streaming service. The monitored information is also stored...
An existing network video monitoring system has already realized putting independent video sources online, to monitor, manage and share resources in unison, in use of IP-based network. With the popularization of wireless network, system should resolve the bandwidth bottleneck in order for good of support for wireless video's uploading technology. So as to improve user experience, it is very important...
Due to the large amount of users of the next generation IPTV system and the limitation for RTCP control messages below 5% of the total allowed bandwidth, the traditional RTCP feedback framework caused large intervals when sending feedback messages from each receiver. To solve these problems, the hierarchical feedback model is proposed in this paper and combined to the design of video quality monitoring...
A stand-alone tool for monitoring selected sites for user defined study topics is described. The "IQ" tool has been developed by OS Vision to allow Open Source Intelligence analysts to define their areas of interests in a flexible way. IQ is also a front-end analysis tool that can connect to one of several real-time information retrieval systems. The first system is OSVision's proprietary...
