One of the most profitable and emerging high-tech markets is the one that involves games for PC and consoles; a market that is growing year by year and that is rapidly evolving. Several big game corporations are implementing now the remote video streaming through the domestic network between two devices; a feature that regards not only PCs but also consoles. This paper investigates one of the main...
An important aspect in providing Internet access is the cost for both fronthaul as well as backhaul connectivity, ultimately providing the access to the wider Internet content and services to the local community. The proliferation of media-rich content has led to a dramatic increase of backhaul costs, while creating pinching points in the often also limited fronthaul network that faces the end users...
The issue of content placement for video streaming over cellular networks is addressed in this study. Our method was verified using real video streaming data taken from traces of live content distribution networks. Simulation results show that replicating a relatively small number of video files can significantly reduce the incoming bandwidth from the Internet backbone, as well as the (time) latency...
Peer-to-Peer systems was developed to compensate limitations of the internet and to reduce traffic among the nodes. In this way data transmission will be quicker and data distribution will be faster. One of the famous P2P distribution systems is BitTorrent. BitTorrent has gained reputation by its remarkable performance in distributing large files over the internet. Since BitTorrent and other P2P systems...
Telehealth applications such as Video-over-IP and remote sensor monitoring are rapidly growing in utilisation and it has now expanded to the patient's homes. These Telehealth applications are, however highly delay sensitive and require high quality (and bandwidth priority) in order to provide satisfactory performances. However, at the patient's home area network (HAN) environment, typically there...
Companies increasingly rely on Internet for effective and efficient business communication. As Information Technology (IT) provides the infrastructure backbone for business activities, a corporate network connects the company to Internet and enables it to perform its activities globally. The corporate carries data packets generated by the users' while performing their business tasks. Traditionally,...
Best Effort service has been the bedrock of the Internet. The simultaneous offering of Managed Service has been proposed as an efficient way to support quality of service, to make some applications feasible and many others more attractive, and give consumers greater choice. However, there is widespread concern that if a network provider is allowed to offer Managed Service and charge a per-use fee,...
TCP remains the dominant transport protocol for Internet traffic, but the preponderance of its congestion control mechanisms in determining flow throughput is often disputed. This paper analyzes the extent to which network, host and application settings define flow throughput over time and across autonomous systems. Drawing from a longitudinal study spanning five years of passive traces collected...
Attempts by the research community to meet expectations arising from future Internet systems, and specifically to provide Quality of Service (QoS) for multimedia multi-user sessions, have resulted in mechanisms such as MultiUser Aggregated Resource Allocation (MARA). Its results have been promising, mainly because it drastically reduces signaling and processing overhead, despite its limitations in...
Heterogeneous wireless sensor network (HWSN) consists of sensor nodes with different ability, such as computing power and sensing range. Compared with homogeneous wireless sensor network, the design of protocols for such networks has to be more complex due to the energy constraint in order to prolong the lifetime of the network. As energy consumption mostly comes from the radio transmissions, bandwidth...
Named Data Networking (NDN) is a clean slate Internet paradigm that embeds some security primitives in its original design, which is being considered as one of the promising candidates for next-generation Internet architecture. However, it may suffer from some emerging threats such as Interest Flooding Attacks (IFA), which means corresponding security management mechanisms need to be designed to improve...
Network steganography is an emerging research field, which exploits packet protocol headers, protocol mechanism, packet payload, etc. to establish secret communication between two parties over a computer network. The detection of such hidden communication has not been part of intrusion detection systems that are primarily used to detect malicious activities such as viruses and malwares. In this paper,...
Distributed systems have rapidly changed the face of Internet Technology. Web syndication is a competitive collaborative content delivery system over the cloud, which refers to making web feeds/ material available from a site to other people with a summary of the website's content including the recent updates. The relevance of web syndication has been remarkable in the fields of e-Governance, e-Commerce...
The Internet of things has reached a stage that allows ubiquitous data access. Still, practical limitations remain in networks with scarce bandwidth. Here, we examine the Bloom filter data structure and its use in distributed protocols. We discuss how to minimize the bandwidth and energy usage consumed when distributed protocols exchange Bloom filters, through dynamic Bloom filter resizing. We propose...
The classic layered OSI reference model has reached its limits for the Internet of today. In this paper, we propose a clean-slate conceptual design of a new architecture as a contribution to the ongoing discussion on the Future Internet. We address the shortcomings of the layered model by redesigning the classical model. Our approach differs from the concepts found in prior work, which focus on special...
This work presents a simulation study of the influence of a multiplexing method on the parameters that define the subjective quality for online games, mainly delay, jitter and packet loss. The results for an available subjective quality estimator from the literature are also shown. Two buffer implementations, each one with two buffer sizes, are tested in order to study the mutual influences of the...
Stream Control Transmission Protocol (SCTP) was introduced in 2001 as a multipath variant to traditional transport protocols, i.e. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Concurrent Multipath Transfer (CMT) has been proposed as an extension for SCTP to support concurrent usage of available multiple paths. In this paper, we propose a new congestion control algorithm for...
The amount of P2P traffic is rising quickly, so that an increasing research focuses on P2P traffic control issues. In this paper, we propose a cooperation strategy called HIC in the aim of controlling cross-ISP traffic without scarifying the system performance. We introduce an incentive mechanism and hidden coordinator of ISP into HIC. The incentive mechanism is used to guide P2P traffic to hidden...
A new network architecture and routing method based on percolation for the Machine-to-Machine (M2M) stub network of Internet of things is proposed. The proposed network architecture is router-free, in which efficient routing can be operated with percolations based on the six degrees of separation or small world network. A file transmission will be divided into two phases: routing phase and data transmission...
Video has become an integral part of the Internet user content. The use of High Definition (HD) video content increases the bandwidth requirements of the Internet infrastructure. Moreover, rapid increase in the Over-the-Top (OTT) Internet video bandwidth consumption has major impact on the business models of the Internet Service Providers (ISP). To support the ever-growing demand for IP-based video,...
