Short range ad-hoc wireless networks can be used to deliver streaming multimedia for information, entertainment and advertisement purposes. To enable short-range communication between various devices, the Wi-Fi Alliance proposed an extension to the IEEE802.11 Wi-Fi standard called Wi-Fi Peer-to-Peer (P2P). It allows compliant devices to form ad-hoc communication groups without interrupting conventional...
Nowadays, 360-degree video has become an important component of virtual reality (VR) technology. Unfortunately, this state-of-the-art content type requires a huge bandwidth from a server to a client. In order to solve the bandwidth problem in streaming VR videos over HTTP/2, a dynamic adaptation method is crucial. In this paper, we propose a novel adaptive streaming method based on tiled streaming...
The latest experiences hint that the QoS (Quality of Service) approaches adopted by IMS (IP Multimedia Subsystem) technologies are still suffering from a primary containment factor due to the nondifferentiation between IPTV (Internet Protocol Television) video components. The success of IPTV services depends on how the customer perceives QoS related to the provided stream. The satisfaction of this...
In today's highly competitive market, the industry must focus on production yield to keep a competitive advantage. Through Automatic Optical Inspection (AOI) or Automated Visual Inspection (AVI), products can be monitored the situation and improved the quality of production. With the development of network technology, operators can use the graphical user interface (GUI) to capture remote visual images...
There is a strong focus on the use of Web Real-Time Communication (WebRTC) for many-to-many video conferencing, while the IETF working group has left the signalling issue on the application layer. The main aim of this paper is to create a novel scalable WebRTC signalling mechanism called WebNSM for many-to-many (bi-directional) video conferencing. WebNSM was designed for unlimited users over the mesh...
BTLive is a novel, unique, mesh/push-based peer-to-peer (P2P) live video streaming mechanism. Previous studies show that it achieves significantly lower streaming delays than other approaches but suffers from a high overhead, where peers receive up to 33% duplicate video chunks. Other P2P streaming mechanisms, most of which are either mesh/pull or tree/push-based, do not experience duplicates at such...
To cope with the varying delay and bandwidth requirements of today’s mobile applications, mobile wireless networks can profit from classifying and predicting mobile application traffic. State-of-the-art traffic classification approaches have various disadvantages: port-based classification methods can be circumvented by choosing non-standard ports, protocol fingerprinting can be confused...
Many BitTorrent clients are using these networks as a video-on-demand service, taking advantage of the popularity and the enormity of the collection of media available. However, it is a common sense that transforming the swarms into an on-demand media service causes serious damage to the overall network performance, given that streamer clients modify the method of downloading determined in the protocol...
Quality of Service (QoS) in networking is a way of managing the network resources effectively. QoS has been widely used in traditional network and can also be implemented in Software Defined Network (SDN). Software Defined Network is a new network paradigm that decouples the control plane from the data plane in the network and thus create a network that is scalable, dynamic and easily manageable....
OpenFlow/Software-Defined Networking (SDN) is a new networking paradigm that virtualizes network infrastructure by decoupling the control and data plane logic of traditional network devices. The controller of SDN has the overall look about network topology and hence provides flexibility to network operators to implement its own routing approaches. However, it could not control the way client works...
Currently, 4G mobile communication systems are supported by the 3GPP standard. In view of the significant increase in mobile data traffic, it is necessary to characterize it to improve the performance of current wireless networks. Indeed, video transmission and video streaming are fundamental assets for the upcoming smart cities and urban environments. Due to the high costs of deploying a real LTE...
This paper describes a flexible multimedia stack which provides media content from number of different streaming protocols. The main goal is to facilitate and accelerate integration with different TV and Set Top Box platforms. Presented solution can be used on Android as well as on Linux based systems. Advantages of this solution are unified data flow and processing of media data. It provides elementary...
Live media streaming applications are increasingly popular, with services such as Twitch.tv and YouNow being used by millions of people. Deploying such services on the cloud can be very expensive, as the cost is proportional to the amount of data transferred to the users. However, adopting a much less costly peer-to-peer (P2P) solution may reduce the overall quality-of-service (QoS) experienced by...
Streaming media applications generate a sizable part of network traffic and represent a significant proportion of network providers' income. The commitment to user satisfaction can be summarized by different concepts, content providers emphasizing quality of experience (QoE), whereas network providers are more focused on quality of service (QoS). Measuring QoS parameters, and understanding the relationship...
Mobile devices have become quite popular, and they are responsible for a significant part of Internet traffic. In these devices, multimedia services, such as video streaming over HTTP, are commonly adopted, and TCP protocol is the standard to assure reliable data transmission. To deal with applications that require higher bandwidth, several modifications were made on TCP, and they are called extensions...
Single-source HTTP Adaptive Streaming protocols (HAS), such as MPEG-DASH, have become the de-facto solutions to deliver video over the Internet. By avoiding buffer stalling events that are mainly caused by the lack of throughput at client or at server side, HAS protocols increase end-user's Quality of Experience (QoE). We propose to extend HAS capabilities to a pragmatic DASH-compliant Multiple-Source...
Abstract-With the rapid development of streaming media, communications between Device-to-Device is becoming a magnetic solution to improve the performance of cellular network.Although numerous papers have been published in the past, most of them just focus on novel description but ignore the classical theory to be innovated. In this paper, inspired by BitTorrent protocol, we propose a dynamic d2d...
Many video streaming services employ the dynamic adaptive streaming over HTTP (DASH) technique to achieve better user's QoE. Named-data Networking (NDN) can bring many benefits to the video distribution with in-network cache and stateful forwarding. However, simply applying DASH technique to NDN causes problems. First, in-network cache may affect download time which makes bitrate adaptation a difficult...
Many BitTorrent (BT) clients are using these BT networks as a video-on-demand service, taking advantage of the popularity and the large collection of media available. However, transforming the swarms into an on-demand media service can cause serious damage to the overall network performance. In this paper, we propose a methodology, using the concepts of Entropy, and present a Spy BitTorrent client...
Vehicular Ad-hoc Networks (VANETs) has witnessed significant attention from academia and industries, due to the growing number of applications and devices focusing on safety and efficiency in transportation. Video Streaming in Vehicular Communication (VSVC) presents interactive real-time view of an emergency incidence on roads. On-board unit of vehicles are utilized for streaming real time video of...
