The increasing demand of global video traffic presents a grand challenge for Internet service providers. This is particularly important for Smart Cities, where the citizens will be surrounded by various multimedia services. The Information Centric Networking (ICN) paradigm has been proposed to handle the vast amount of data, mobility of users, and provide better scalability and efficiency in terms...
Video traffic is a key-challenge for fixed and mobile operators facing variable and massive load and variety of Over- The-Top (OTT) videos. Energy consumption is also a heavy Opex component, where the Fixed-Mobile Convergence is a promising solution, built on on economical optic fibers and LTE baseband operations consolidation. By combining Future Internet Architectures (FIA) principles such as ubiquitous...
Modern internet traffic is heavily composed of some form of video communication. In addition, video streaming is slowly replacing regular phone connections. Given that most video transport utilizes Video over Hypertext Transfer Protocol/Transmission Control Protocol (HTTP/TCP), it is important to understand TCP performance in transporting video streams. Recently, multipath transport protocols have...
Named Data Networking (NDN) is a promising Future Internet architecture to support efficient content distribution. Specifically, P2P may gain benefits from NDN, as NDN inherently provides a flexible forwarding plane for multi-source and multi-path communications. Existing studies in this area have proposed solutions, but these are adversely affected by link latency. This leads to illogical resource...
MPEG Dynamic Adaptive Streaming over HTTP (DASH) has become the most used technology of video delivery nowadays. Considering the video segment more important than its location, new internet architecture such as Content Centric Network (CCN) is proposed to enhance DASH streaming. This architecture with its in-network caching salient feature improves Quality of Experience (QoE) from consumer side. It...
5G services and 4K will stress even more the future access/aggregation networks, where video contents have already become the main traffic contributor. The deployment in the convergent access of local micro data-centers (DCs) nodes is one promising approach to successfully manage this challenge. These nodes will be responsible for switching enormous amounts of traffic and simultaneously performing...
The progression of cheaper, faster and more reliable Internet technologies leads Internet of Things (IoT) to be applied in various fields of life nowadays. While tremendous data are generated and delivered from IOT devices, it is essential on the server side having scalable and effective data compression techniques to balance storage usage and data precision. This paper presents an adjustable content-sensitive...
Aggregating multiple access interfaces of a client is a promising way to satisfy the high bandwidth demand by high-definition video streaming services. However, how to efficiently use such aggregated bandwidth to improve the reliability of timely fetching video contents needs to be further studied. In this paper, we propose a partial overlapping chunk based dual-path transmission scheme, which uses...
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...
The more stringent requirements of many applications services — especially in terms of latency and bandwidth — is leading to the migration from data center based architecture towards a mobile-edge computing paradigm. This emerging network architecture aims to increase the overall infrastructure efficiency by delivering low-latency and bandwidth-efficient services. In this context, a not fully investigated...
This paper presents a framework for a firewall to analyze and block BitTorrent file-sharing protocol using Traffic Analysis (TA) methods. BitTorrent traffic can be a concern of network administrators and is a valuable target for TA based investigation. In this work, the ability of a TA based classifier to identify the existence of BitTorrent traffic is tested under the condition that it is not only...
In recent years, video streaming services based on the client server (C/S) model have become common. When distributed through these services, video files need to be watermarked with a unique ID to identify clients, so as to deter illegal video capturing. However, the download bandwidth at servers limit the number of clients that can view video files simultaneously. With peer-to-peer (P2P) communication,...
Real-time video streaming communication is the key technology for intelligent device. In this paper, we discuss the video communication on the hardware platform of both IP vidicon and STB, and analyze the IP vidicon system software based on RTSP protocol on sever client. A self-adaptive stream transmission method for STB use client is proposed. It achieves the real-time video communication between...
This paper introduces a surveillance system that can be deployed in various environments such as home security or child protection. It takes the advantage of video sharing platforms like YouTube to provide live streaming to the end users free of cost. Any user can create live events via this application anywhere on the fly. This system is mainly an Android based application that can harness 3G/HSPA...
Since the early days of Quality of Experience (QoE) research, relationships to Quality of Service (QoS) and corresponding QoE-QoS models have been of great interest to the research community. However, the manifold quality transformations throughout the communication stack, together with accessibility issues of QoS parameters inside networks, hamper availability, applicability and generality of such...
Coded caching is a technique that receives much attention in the network literature, since it is able to achieve significant gains compared to the conventional uncoded caching schemes. In this paper, we first identify a family of placement and delivery schemes. Then we derive a lower bound on the average rate for the identified schemes. Based on the clue in deriving the lower bound, a new delivery...
Video broadcasts on the Internet have become a commonplace and increasingly find their audience, supported by popular video services and social networks. But there are tasks, that require content delivery network (CDN), which lead to extra expences, and moreover, does not give sufficient flexibility and limits personalization of the broadcasts. This paper presents the principles of creating a flexible...
To stream video using HTTP, a client device sequentiallyrequests and receives chunks of the video file fromthe server over a TCP connection. It is well-known that TCPperforms poorly in networks with high latency and packet losssuch as wireless networks. On mobile devices, in particular, usinga single TCP connection for video streaming is not efficient, andthus, the user may not receive the highest...
Peer to peer networks offer an extensible framework for supporting video streaming service over the Internet. P2P networks efficiency highly depends on peers' contribution. In practice, some peers only use the service, but share few resources or do not share any resources. This phenomenon is called free riding which seriously affects the P2P networks efficiency. So, in order to encourage the peers...
Today Peer-To-Peer (P2P) networks are becoming more important from high scalability and low cost point of view, and these networks are popular platform for video streaming. With burgeoning of P2P networks, one of the interesting areas of research is confronting to various attacks and threats against these networks. Since, video streaming is a popular application of P2P networks, some attacks like...
