The long-term vision of an Internet of Things (IoT) is approaching reality and leading hardware vendors expect shipment of 50 billion devices in the near future. Emerging Internet standards will enable this huge number of embedded machines to interconnect and cooperate—and raise the challenge of building suitable software environments that provide scalability, reliability, and security at an efficient...
Recently, Wireless Mesh Networks (WMNs) have attracted much of interest from both academia and industry, due to their potential to provide an alternative broadband wireless Internet connectivity. However, due to different reasons such as multi-hop forwarding and the dynamic wireless link characteristics, the performance of current WMNs is rather low when clients are soliciting Web contents. Due to...
Energy efficiency in P2P systems has become a prominent issue due to significant portions of the Internet traffic devoted to P2P protocols. In this paper, we address the approaches for energy efficiency in BitTorrent Protocol. First, we provide a classification of the existing energy efficient BitTorrent studies, and then propose multi-proxy and private proxy approaches to minimize energy consumption...
Wireless Mesh Network (WMN) is an emerging and practical wireless solution for metropolitan area networks to provide community broadband Internet access services by organizing and configuring nodes in the network efficiently and dynamically. In this survey, the concept of wireless mesh network has been described briefly as an emerging technology to provide Internet in large areas. Accordingly, the...
The so-called Internet of Things (IoT) presents a tremendous opportunity for multitude of users to be connected to anything, whenever needed, wherever needed, by whoever needs it. Such opportunities, nonetheless, require more advanced and standardized communication interfaces to facilitate interactions between any types of "things" (smart devices, sensors, systems, networks, etc.). Recent...
Nowadays, a novel BitTorrent technology, Private Tracker, has received extensive attentions in academia. However, most researches work on measuring, analyzing and modeling of Private Trackers towards to Internet or networks. Few work aims at utilizing the PTs model to real life. In this paper, we abstract the idea of PTs model to a universal trade exchange mechanism creatively, and apply it to real-world...
Information Centric Network or ICN is one of the few popular designs envisioned for the future Internet. In ICN, packets are routed by content-object names. Such names can be much more complicated as well as order of magnitude more in quantity than IP addresses, and the same content-objects might also be available for retrieval at more places in the network. As routing tables are always limited in...
An efficient web server fulfills the requirements of the users as with the rapid development in technology. All the web contents accessed through Internet serviced by a web server in content distribution networks (CDN). Web server distributes web pages to respective clients as a first priority. To increase the performance, scalability and efficiency, the web server needs a peer-to-peer (P2P) network...
Online sharing of digital assents have now become common in the internet by its increased number of users over a decade drastically. There are many online sharing resources which offer huge storage. These facilities tend the internet users to upload and download pirated softwares, movies and other similar digital assets which violates all copyrights. The P2P protocol is working behind such online...
Within the Future Internet, a new trend is foreseen with the creation of overlay networks composed of residential gateways (i.e. Home-Box), leveraging their storage and upload capacity in order to achieve scalable and cost-efficient content distribution. In this paper, we highlight an architecture of such a home-box overlay for Video On Demand (VOD) services, in cooperation with a network-aware request...
The rapid development of crowd sensing and cloud computing makes it possible to build world wide Cyber Physical Systems (CPS). Range queriable P2P overlay technologies are considered as promising candidate for realizing some important functionalities of CPS, for example, retrieval based on the properties of sensors. However, it is difficult to build world wide systems with existing range queriable...
A network delay predictive modeling method based on system identification is proposed to match the latency between two agents of networked control systems(NCSs).With the prediction, historical and estimated data compose a time-related series to describe the future network delays as explicit time-related function. By the proposed model, how to optimize the transmission path among multi-agents is converted...
Content replication and placement is an effective technique to improve data availability and enhancing network performance. This area received attention in Content Delivery Networks (CDNs), but is less explored by the research community in Wireless Mesh Networks (WMNs). A number of replica placement algorithms were specifically designed for CDNs, but they do not consider the special features of wireless...
Multipath routing can provide a better solution for several of the current BGP's problems in the inter-domain scenario by allowing a cleaner separation between routing and traffic engineering and better failure containment. The separation between routing control logic and data forwarding, and the use of software defined networking principles open space to easier deployments of new routing protocols...
The decentralized nature of Peer-to-Peer (P2P) botnets makes them difficult to detect. Their distributed nature also exhibits resilience against take-down attempts. Moreover, smarter bots are stealthy in their communication patterns, and elude the standard discovery techniques which look for anomalous network or communication behavior. In this paper, we propose Peer Shark, a novel methodology to detect...
For unstructured peer-to-peer (P2P) networks, we previously proposed an efficient digital content sharing method, in which content searching queries are guided properly to an appropriate peer which is likely to store a replica of target content item, by using query transmission records (TRs) maintained in each peer. In this paper, we improve the conventional method and make it achieve more efficiency...
Wireless Sensor Networks (WSNs), as a key part of the Internet of Things (IoT), allow the representation of the dynamic characteristics of the physical world in the Internet's virtual world. Thus, sensor nodes are henceforth considered as Internet hosts and may act freely as web clients or servers. Undoubtedly, security and end-users privacy issues rise and become more severe in the IoT, due to the...
Botnets are a well recognized global cyber-security threat as they enable attack communities to command large collections of compromised computers (bots) on-demand. Peer to-peer (P2P) distributed hash tables (DHT) have become particularly attractive botnet command and control (C & C) solutions due to the high level resiliency gained via the diffused random graph overlays they produce. The...
The Internet has become a large platform where users can interact and share contents. In this context, content distribution systems (CDS) have been designed to satisfy users needs. Peer-to-Peer (P2P) systems have emerged as a prominent solution to speed up CDS. In this kind of distributed system, a particular interesting challenge refers to mechanisms employed to match user's interests and published...
Bittorrent is one of the most popular file sharing applications on the Internet. It is well-known that its success mainly depends on its user cooperation. Systems with a small number of altruist users or without incentive mechanisms are fated to failure. This paper discusses the influence of Facebook on Bittorrent swarms. We analyze data from more than 16,600 Bittorrent swarms disseminated by Facebook...
