Applications of Fog Computing in Video Streaming

The purpose of this paper is to show the viability of fog computing in the area of video streaming in vehicles. With the rise of autonomous vehicles, there needs to be a viable entertainment option for users. The cloud fails to address these options due to latency problems experienced during high internet traffic. To improve video streaming speeds, fog computing seems to be the best option. Fog computing brings the cloud closer to the user through the use of intermediary devices known as fog nodes. It does not attempt to replace the cloud but improve the cloud by allowing faster upload and download of information. This paper explores two algorithms that would work well with vehicles and video streaming. This is simulated using a Java application, and then graphically represented. The results showed that the simulation was an accurate model and that the best algorithm for request history maintenance was the variable model

Business Case and Technology Analysis for 5G Low Latency Applications

A large number of new consumer and industrial applications are likely to change the classic operator's business models and provide a wide range of new markets to enter. This article analyses the most relevant 5G use cases that require ultra-low latency, from both technical and business perspectives. Low latency services pose challenging requirements to the network, and to fulfill them operators need to invest in costly changes in their network. In this sense, it is not clear whether such investments are going to be amortized with these new business models. In light of this, specific applications and requirements are described and the potential market benefits for operators are analysed. Conclusions show that operators have clear opportunities to add value and position themselves strongly with the increasing number of services to be provided by 5G.Comment: 18 pages, 5 figure

Analysis and Summary of Feasible Marketplace Business Models Covering All Trials

This report analyses the market for cloud services of the type that POSTMARK is pioneering including type, scale, readiness and barriers to adoption. The POSTMARK trials are reviewed in terms of the business benefits that the services offer, the validation of these by those involved in the trials, and the further work needed to move from trials to a fully commercial and production setting. Business benefits were wide ranging and included lowering costs, better meeting of deadlines, increase in volume of business, and improved customer service. Response from the trials was positive in all cases. This was echoed by the two public demonstration events hosted by the project in 2012 where the attendees (around 100 in total from the film and post communities) were positive about the services that POSTMARK is offering. The main barriers encountered were security, the need for high levels of availability and trust, the need for complete out-of-the box solutions, and of course concerns over cost. These mirror findings in industry surveys and analyst reports. These barriers are not insurmountable but do require further investment to address. The key question is whether the market as a whole is sufficiently aware of, and ready to adopt, new services of the type developed by POSTMARK.Indications are good, but large scale adoption would be necessary to give sufficient return on the investmentneeded to provide fully operational POSTMARK services on a supported and commercial basis

City Magazines and Social Media: Moving beyond the Monthly

City magazines have long been established in many American locales, but digital media of all types are now offering opportunities and challenges to this genre of magazine. Digital media have also complicated the rapidly changing ecosystems of local information in which urban citizens reside. The resources and popularity of newspapers and broadcast news have shifted, and other forms of print, digital, and mobile media are assuming important roles in informing the public. With all these factors at work, this may be a pivotal moment for city magazines as they explore innovative technology, creative business strategies, and the new possibilities for coverage that these offer. As part of a larger, multi-method project, this study analyzes to what degree city magazines are using Twitter to move beyond a monthly publication schedule, to activate and engage audiences in new ways, and to address local topics and concerns. This study reveals that city magazines are informing the public and engaging their audiences through social media in limited but promising ways. It also strongly suggests that these magazines may indeed be using technology to move beyond their traditional monthly publication schedule and become a more vibrant part of local audiences’ information environment

Region Codes and the Territorial Mess

Tourists, frequent travelers, and foreign film aficionados hate DVD region codes with a passion. Written for the 30th Anniversary Symposium of the Cardozo Arts & Entertainment Law Journal, this article critically examines the expediency of using region-based restrictions to protect copyrighted media content. The article begins by closely examining four justifications for the deployment of DVD region codes: sequential release; price discrimination; distribution and licensing agreements; and censorship ratings and regulatory standards. It also identifies four areas in which DVD region codes have created unintended consequences: consumption, competition, cultural rights, and censorship. The article then advances three proposals to address the shortcomings of DVD region codes: the voluntary removal of these codes; the provision of affordable multiregion players; and the introduction of a right to circumvent. It concludes by warning that, with the proliferation of streaming platforms, device-embedded applications, and cloud computing, region-based restrictions could have a more significant impact on consumers in the near future

Economic benefit of the National Broadband Network

This paper argues that all regions benefit from the NBN but the economic effects are greater in the major cities because of their larger economic activity. Executive summary This paper is a partial summary of a study undertaken in the Centre for Energy-Efficient Telecommunications (CEET) at the University of Melbourne. The study focuses on the potential economic impact of Australia’s NBN. The NBN affects the economy by making online services more widely available. Taking a conservative approach, we have considered just six categories of online services (cloud computing, electronic commerce, online higher education, telehealth practice, teleworking, and entertainment) from which there are documented economic benefits. We have attributed to the NBN only the additional benefit derived from its deployment over and above what we estimate would have been the broadband situation in Australia without the NBN. That is, we have not assumed that broadband availability would have stagnated without the NBN. We do expect, however, that future services will require higher access speeds, generally in the range 10-25 Mb/s. With this assumption and using a well-attested model of the Australian economy, we show that, in the long term, real GDP can be boosted by about 1.8% and real household consumption (a measure of national welfare) by about 2.0%. When we take into account the need to repay the cost of the NBN, GDP increases slightly but the benefit to real household consumption is reduced to 1.4%. Most of the benefit comes from telehealth and teleworking. Because the access speeds (downstream and upstream) required for the services are quite uncertain, we have looked at the effects of access speeds. If all the services except entertainment can be provided with no more than 2.5 Mb/s down and up (typical of implementations today), then the costs of the NBN outweigh the benefits. Real GDP increases by less than 0.2% but real household consumption declines by 0.4%. That is, building an NBN just for entertainment is not economically viable. An analysis of the regional distribution of benefits shows that all regions benefit from the NBN but the economic effects are greater in the major cities because of their larger economic activity

Persuasive design of a mobile energy conservation game with direct feedback and social cues

Pervasive gaming has the potential of transforming the home into a persuasive environment in which the user can learn about appliances and their electricity consumption. Power Explorer is a mobile game with a special sensing approach that provides real-time electricity measurements and feedback when the user switches on and off devices in the home. The game was developed based on persuasive principles to provide an engaging means to learn about energy with positive and negative feedback and social feedback from peers on real energy actions in the home. We present the design and rationale of this game and discuss how pervasive games can be viewed from a persuasive and learning point of view
