Building upon “WhiteNet”, a white space network management platform for campus connectivity, this paper proposes design principles that can be incorporated in a white space identification system based on a cooperative spectrum sensing model that both minimizes the probability of causing interference to primary users due to false negatives and reduces false positives thereby increasing the amount of white spaces identified. Real-world indoor measurements of a TV transmitter signal were used to evaluate the proposed principles. The results reveal the relevance of using these design principles in white space networking using the emerging White-Fi protocol.","PeriodicalId":394466,"journal":{"name":"J.

Nevertheless, for today, there is the lack of QoS related 3GPP and ITU-T recommendations describing various popular services, for example video conferencing. The problem is to find the optimal bit rate values for this service not affecting the background lower priority services. In this paper, we propose a tool to solve this problem. The tool includes, first, a mathematical model of pre-emption based radio admission control scheme for video conferencing and background video on demand, and second, an effective algorithm for calculating QoS parameters for these services. The results of the paper could be used to find the optimal bit rates for video conferencing and further develop a proposition for standardization activities in video conferencing recommended parameters. ∗The reported study was partially supported by RFBR, research project No. 13-07-00953.

The stereoscopic video signals used in the application are based on a two-view model, such as the H.264/AVC standard in the Multiview Video Coding (MVC) profile. In addition, several spatial resolutions are available. The application provides objective video quality algorithms, such as PSNR, SSIM, and PW-SSIM and also incorporates a recently published technique for stereoscopic video quality assessment called Disparity Weighting (DW), which comprises the following algorithms: DPSNR, DSSIM and DPW-SSIM. Numerical results corresponding to the performance of the objective measurements, acquired using the proposed application, are presented. The application aims to contribute to the standardization and development of objective algorithms for stereoscopic content. As an open-source tool to be used by the academia and the industry, the application is used to evaluate impairments in stereoscopic video signals, caused by processing, compression and transmission techniques.

As there is a rapid explosion of web-based content, it becomes challenging to provide quality of experience to the end-user. To efficiently handle the utmost growth of the Internet content, in business perspective, there is a clear increase in Content Delivery Networking (CDN). On the other hand, in research perspective it is the Information Centric Networking (ICN) which emerged as an alternative to the current host-to-host communication paradigm and has the potentials of distribution and retrieval of contents more efficiently. This article is an initiative to find some rooms where the ICN and the CDN can meet together. In ICN, a potential strategy by the publisher ignores CDN providers and has direct connections with ISPs. However we believe that, at the stage of incremental deployment of ICN, there is no scope of ignoring CDN. Besides, it is true that it will take time to deploy ICN in Internet scale. So, for achieving big economy of scale publisher will choose CDN as a means for its content distribution. In this paper we present two possible content distribution models for ICN. We formulate game theoretic model for the network players for ICN architecture based on our proposed content distribution model. Firstly, we Journal of ICT, Vol. 2, 201–222. doi: 10.13052/jicts2245-800X.231 c © 2015 River Publishers. All rights reserved. 202 M. Arifuzzaman et al. present two player game model between Publisher and Telco CDN. And we discuss the way of Revenue sharing between Telco CDN and Telco CDN (or Telcos or ISPs); where we assume that interconnection among Telco CDNs is possible. Following, we enhance the game among three major network players (Publisher, Global CDN and Telco CDN) of ICN to analyze the way of the economic incentives sharing among them. We also present a solution for Live Streaming Media broadcast in ICN and analyze the economic part with a decision tree. Besides, we identify some standardization issue in ICN architecture and we emphasize on the need for a common standard for content routers (CR) so that as a node in the ICN, CR ensure scalable content delivery as well as its functionalities match with the Internet open standard philosophy.","PeriodicalId":394466,"journal":{"name":"J.

These sources, sometimes referred to as the Internet of Things (IoT), will consist of devices such as sensors, monitors and smartphones. This trend has been made possible because of (a) the adoption of IPv6 (allowing for such devices to be addressable), (b) enhancements in cellular technologies (in particular 5G) to better support short infrequent bursts of data transmissions and (c) the introduction of smartphones with a wide range of sensors and (d) the availability of easily deployed, low cost, low energy sensors (helped by the introduction of Raspberry Pi and Arduino processors). The real-time data generated by these devices can serve be used in several ways including being mined for important information and correlations, as well as use in web and mobile applications. This data, however, is often either proprietary or in a format that is not easily usable by real time applications. Furthermore, if an application developer needs to integrate (mash-up) data from multiple sources it is quite burdensome to develop interfaces. The present platforms for open data repositories are designed for static non real-time data. We propose a design and provide specifications for a platform that will accept real-time open data from multiple sources in multiple formats and make the data accessible in a standard format at user specified frequencies. The data is held for a finite period of time and digests made so that developers can also make use of historical data.
