The IP Multimedia Subsystem (IMS) is a kind of Multimedia business form and it is an architectural framework for delivering IP multimedia services. In order to increase flexibility and reliability, in this paper we propose a different perspective which maintains the existing IP Multimedia Subsystem (IMS) based signaling platform while processing flow via distributed SDN controllers. Software Define...
In Recent times Wireless sensor network (WSNs) has become one of the most interesting networking technologies since, it can be expanded without communication infrastructures. Wireless sensor network face certain limitations such as power, data redundancy and high bandwidth requirement when used for multimedia data .The researchers have focused on the video encoding at the multimedia sensors side,...
The advance in vehicular and wireless communications has contributed to the release of Vehicular Clouds which makes it possible to release various multimedia and storage services. However, providing a communication service which allows to cope with the high mobility of vehicles, and the limited availability of wireless resources, while guaranteeing a high quality of service (QoS), is a challenging...
We propose and present CONIA, a novel content (provider)-oriented, namespace-independent architecture for multimedia information delivery. CONIA is designed specifically to account for the diversity and complexity of multimedia content, and to recognize the prominent roles of content providers (CPs) in the network economics of content delivery. In this paper, we provide an overview of the content...
Software Defined Networking (SDN) and Named Data Networking (NDN) are two topics which have received lots of attention in the networking research community in recent years. While both have emerged independently from each other we believe that their core features can be well aligned to each other. Hence combining both may hold potential benefits for network operators. In this paper we investigate the...
Mobile devices are increasingly used as terminals for playback of multimedia content. However, maximizing the user's quality of experience is challenging due to the highly variable conditions of the wireless channels. A possibility to cope with such a variability is to dynamically adapt the source coding rate during the transmission, which is the underlying idea of the DASH standard. This work proposes...
Today, when the content provider transmits a video, he usually uses forward error correcting to protect the packets which caused a lot of redundancy. If we know parts of the media stream are more important than others, we can uses bandwidth more efficiently. In this paper, we analyze the structure of the video stream, the frame types and the dependence among frames and propose an optimized scheme...
The popularity of multimedia services offered over the Internet have increased tremendously during the last decade. The technologies that are used to deliver these services are evolving at a rapidly increasing pace. However, new technologies often demand updating the dedicated hardware (e.g., transcoders) that is required to deliver the services. Currently, these updates require installing the physical...
The device people use to capture multimedia has changed over the years with the rise of smart phones. Smart phones are readily available, easy to use, and capture multimedia with high quality. While consumers capture all of this media, the storage requirements are not changing significantly. Therefore, people look towards cloud storage solutions. The typical consumer stores files within a single provider...
This paper presents an analysis of a rate adaptive multimedia streaming technique according to which rate changes are obtained by varying the inter-packet transmission interval, rather than altering the source coding rate. Instead of constraining the transmitter to operate in real-time, the time scale of the proposed packet scheduler can vary between zero when the network is congested, to as faster...
In this paper we implement a recurrent high order neural network based controller (built into a Client-Server architecture), in order to provide QoS control. The scheme is based on a recently proposed QoS control algorithm with proven stability and robustness properties. Mild assumptions have been used to construct a user satisfaction function that depends on two media characteristics (i.e. color...
High-Definition (HD) information is the consumed bandwidth application in Telecommunication network. The quality of service (QoS) on uncompressed High-Definition content transmission with Paralleled Digital Subscriber Lines is needed in smooth information transmission and most tasks on QoS are served by each telecommunication network operator. The Adaptive Rate Control (ARC) is introduced and deployed...
In Multimedia network applications, adaptive mobile streaming empowers cloud-based real time transcoding. The researchers in media cloud propose a well-organized technique to split the video content into different frames. The technique is to carry out disseminated encoding to resolve the multimedia data conversion problem. Also, it introduces an energetic outgoing and an extrapolative bandwidth for...
In this paper, the service scenario & requirements for providing 4K UHD & HD convergence broadcasting services through terrestrial single channel are analyzed by employing the latest transmission and A/V codec technologies. Optimized transmission parameters for 6 MHz & 8 MHz terrestrial bandwidths are drawn, and receiving performances are measured under Additive White Gaussian Noise (AWGN)...
This paper proposes a novel network architecture for optimal and balanced provision of multimedia services, exploiting a resource prediction system. This architecture enables for the long-term prediction of multimedia services future demands, based on the history of previous network resources usage. The proposed research approach provides the opportunity for the optimal distribution of streaming data,...
The flexibility of radio access network facilitated by 5G networks opens the gateway of deploying dynamic strategies for broadcasting TV channels in an efficient way. Currently, spectrum efficiency and bandwidth efficiency are the two common metrics measuring the efficiency of a system. These metrics assess the net bitrate for a unit of spectrum bandwidth. However, there is a lack of measurement,...
Modern learning system offered in a recent era of technology is the one that employ computer and network technology, Video-on-Demand (VoD). The implementation on VoD on learning system presents an opportunity to access the multimedia content any time without concern about place and time. One thing that should be put on apprehension is the bandwidth consume by the architectures. On this paper, we study...
The process of network convergence and the increased availability of high speed networks has opened a number of possibilities in the field of multimedia content distribution. Above all, the popularity of mobile platforms and the accompanying user mobility requires the distribution platforms to be able to respond to changing network conditions and to maintain a satisfactory quality of service regardless...
The development of communication and multimedia technologies makes it possible and practical to exchange high-volume data in Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) in real time. However, the challenges are eminent in the vehicular streaming systems where the network conditions change rapidly. It is meaningful and valuable to develop adaptive streaming technologies that suit the...
Due to the recent popularization of IP multicast, the continuous broadcasting of audio or video media data has attracted great attention. Although servers can concurrently deliver data to many clients, clients have to wait until their data are broadcast. In division based broadcasting, many researches have proposed scheduling methods to reduce the waiting time. A division based broadcasting system...
