Multimedia delivery in the future internet

The term “Networked Media” implies that all kinds of media including text, image, 3D graphics, audio and video are produced, distributed, shared, managed and consumed on-line through various networks, like the Internet, Fiber, WiFi, WiMAX, GPRS, 3G and so on, in a convergent manner [1]. This white paper is the contribution of the Media Delivery Platform (MDP) cluster and aims to cover the Networked challenges of the Networked Media in the transition to the Future of the Internet. Internet has evolved and changed the way we work and live. End users of the Internet have been confronted with a bewildering range of media, services and applications and of technological innovations concerning media formats, wireless networks, terminal types and capabilities. And there is little evidence that the pace of this innovation is slowing. Today, over one billion of users access the Internet on regular basis, more than 100 million users have downloaded at least one (multi)media file and over 47 millions of them do so regularly, searching in more than 160 Exabytes1 of content. In the near future these numbers are expected to exponentially rise. It is expected that the Internet content will be increased by at least a factor of 6, rising to more than 990 Exabytes before 2012, fuelled mainly by the users themselves. Moreover, it is envisaged that in a near- to mid-term future, the Internet will provide the means to share and distribute (new) multimedia content and services with superior quality and striking flexibility, in a trusted and personalized way, improving citizens’ quality of life, working conditions, edutainment and safety. In this evolving environment, new transport protocols, new multimedia encoding schemes, cross-layer inthe network adaptation, machine-to-machine communication (including RFIDs), rich 3D content as well as community networks and the use of peer-to-peer (P2P) overlays are expected to generate new models of interaction and cooperation, and be able to support enhanced perceived quality-of-experience (PQoE) and innovative applications “on the move”, like virtual collaboration environments, personalised services/ media, virtual sport groups, on-line gaming, edutainment. In this context, the interaction with content combined with interactive/multimedia search capabilities across distributed repositories, opportunistic P2P networks and the dynamic adaptation to the characteristics of diverse mobile terminals are expected to contribute towards such a vision. Based on work that has taken place in a number of EC co-funded projects, in Framework Program 6 (FP6) and Framework Program 7 (FP7), a group of experts and technology visionaries have voluntarily contributed in this white paper aiming to describe the status, the state-of-the art, the challenges and the way ahead in the area of Content Aware media delivery platforms

A Review: Analysis of White Space for Designing Communication Module

In this paper we propose the literature review related to analysis of White Space for Designing Communication Module. The radio frequency spectrum is an essential factor in communication network. With demand for wireless connectivity increasing, the exploitation of white space is an attractive way of making more efficient use of radio spectrum. This paper is based on the detecting the unutilized spectrum that can safely be used for broadband communication networks

DVB-T channels power measurements in indoor/outdoor cases

In this paper the analysis of the spectrum occupancy in the TV band is provided based on the indoor and outdoor measurements campaigns carried out in Poznan, Poland, and Barcelona, Spain, in 2013. The goal of this work is to discuss the stability and other important features of the observed spectrum occupancy in the context of indoor/outdoor Radio Environment Maps database deployment. Reliable deployment of these databases seems to be one of the critical points in practical utilization of the TV White Spaces for cognitive purposes inside buildings and in densely populated cities.Postprint (published version

Empirical Study on Performance Evaluation Between Long Term Evolution (LTE), Third Generation (3G) and TV White Space Availability for Wireless Campus Network

Abstract—University campuses are increasingly relying on wireless communication as the preferred media to access the web. Hence, there is a need to conduct on site performance evaluation on the existing wireless standards with the view of analyzing their expected and actual performance. In this paper, a drive-test was performed on three (3) wireless standards of LTE Release 8, 3G and Television White Space (TVWS). The drive-test was performed in both in-building and outdoor environments in a sub-urban campus settings. Results from LTE Release 8, 3G indicate that user mobility affects the received user throughput and Reference Signal Strength Indicator (RSSI). The test cases are executed by using a real LTE user equipment, equipped with ASCOM’s TEMS software on a live 3G and 4G mobile networks for the both Malaysian mobile service providers; Maxis and Celcom. The results showed sufficient coverage within the campus area from both operators. On the other hand, results from field experiment indicate that TVWS is available on the campus. TVWS presents significant new opportunities within the context of emerging 4G networks for deploying new wireless access technology capable of meeting students expectation in terms of throughput and increasing broadband access for the fraction when the legacy 4G networks experience coverage blackout

Application of radio environment maps for dynamic broadband access in TV bands in urban areas

Spectrum sharing based on the dedicated databases, particularly in the context of TV band, is widely considered as a promising tool for better spectrum utilization in the future wireless networks. Practical realization of this paradigm entails the need for the true protection of the incumbent system, and at the same time the guarantee of the quality of the services offered to the secondary users. In this respect, this papers discusses the results achieved in numerous measurement campaigns performed for last years in two European cities, i.e., Poznan, Poland and Barcelona, Spain. Both indoor and outdoor measurements of the TV band have been compared with the main purpose of true identification of key practical considerations for spectrum sharing in the TV white spaces. As such the paper constitutes a concise summary of various analyzes and provides pragmatic guidelines for deployment of radio-environment maps (REM) based systems. Based on the conducted measurements and achieved results, the set of practical conclusions for REMs has been deduced, and the prospective procedure of deployment of such a network has been proposed.Peer ReviewedPostprint (published version
