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

The mobile future of university libraries and an analysis of the Turkish case

İstanbul Technical University, Mustafa İnan Library--(2017)Purpose: Smartphones will very soon become the standard means by which the Internet is accessed, and the rates of connection from mobile devices will supercede those which are computer-based.The hypothesis of this study is that a university library accessible by mobile technology will be the model of the future, and its purpose is to search for any evidence for which the university libraries in Turkey are prepared to meet this challenge. Design/methodology/approach-In the study, both domestic and foreign literature surveys were undertaken to determine which mobile library services are offered in university libraries. 30 random central libraries of both private and state universities were selected from across the 7 regions of Turkey. To gather data, a 26-question electronic survey was generated and e-mailed to the library managers. The questions were based on findings regarding the mobile library services provided by university libraries around the world. Findings-By examining the survey results, it was determined that Turkish university libraries utilise a comparable level of mobile technology, and demonstrate a similar level of care with regard to the services they offer. There are mobile sites (separate sites or mobile sites as applications), mobile library catalogues, SMS services, chatrooms, consultations via IM tools, mobile device lending services, and augmented reality and QR code applications. Research limitations/implications. In Turkey, the structures of university libraries operate under variable conditions due to the lack of established standards. This causes negative results for the delivery of library services. For this reason, university library standards should be set practicable as soon as reasonable, considering the social/economic and cultural structure of the country. Practical implications-Due to the transformative effect technology and the Internet have had on services, “information and communication technologies infrastructure” has been added as a sixth element to the five traditional library items; namely building, budget, personnel, collection, and users. Globalisation through the web has resulted in the individualisation of services, and the slogan “content is king” has been changed to the “customer experience is king”. Fundamental library services are being adapted to allow mobile technology access, and this approach best reflects the new slogan. Therefore, the university library of the future may well be the one entirely based on mobile technology. Social implications: mobile devices lead to new forms of engagement with student learning; so academic libraries are expected to be strong partners in the teaching and learning processes of their institution. Originality/value: The hypothesis of this study is that a university library accessible by mobile technology will be the model of the future, and its purpose is to search for any evidence for which the university libraries in Turkey are prepared to meet this challenge. This study is also meaningful because there have not been any study of Turkish university libraries in terms of mobile library services to users. This paper is the first time that a comprehensive study has been made of current mobile technology-based services, and is also the first comparison of the applications in Turkish university libraries. Additionally paper synthesizes developments and provides suggestions for the future. © Emerald Publishing Limited

Optimal configuration of active and backup servers for augmented reality cooperative games

Interactive applications as online games and mobile devices have become more and more popular in recent years. From their combination, new and interesting cooperative services could be generated. For instance, gamers endowed with Augmented Reality (AR) visors connected as wireless nodes in an ad-hoc network, can interact with each other while immersed in the game. To enable this vision, we discuss here a hybrid architecture enabling game play in ad-hoc mode instead of the traditional client-server setting. In our architecture, one of the player nodes also acts as the server of the game, whereas other backup server nodes are ready to become active servers in case of disconnection of the network i.e. due to low energy level of the currently active server. This allows to have a longer gaming session before incurring in disconnections or energy exhaustion. In this context, the server election strategy with the aim of maximizing network lifetime is not so straightforward. To this end, we have hence analyzed this issue through a Mixed Integer Linear Programming (MILP) model and both numerical and simulation-based analysis shows that the backup servers solution fulfills its design objective

From Sensor to Observation Web with Environmental Enablers in the Future Internet

This paper outlines the grand challenges in global sustainability research and the objectives of the FP7 Future Internet PPP program within the Digital Agenda for Europe. Large user communities are generating significant amounts of valuable environmental observations at local and regional scales using the devices and services of the Future Internet. These communities’ environmental observations represent a wealth of information which is currently hardly used or used only in isolation and therefore in need of integration with other information sources. Indeed, this very integration will lead to a paradigm shift from a mere Sensor Web to an Observation Web with semantically enriched content emanating from sensors, environmental simulations and citizens. The paper also describes the research challenges to realize the Observation Web and the associated environmental enablers for the Future Internet. Such an environmental enabler could for instance be an electronic sensing device, a web-service application, or even a social networking group affording or facilitating the capability of the Future Internet applications to consume, produce, and use environmental observations in cross-domain applications. The term ?envirofied? Future Internet is coined to describe this overall target that forms a cornerstone of work in the Environmental Usage Area within the Future Internet PPP program. Relevant trends described in the paper are the usage of ubiquitous sensors (anywhere), the provision and generation of information by citizens, and the convergence of real and virtual realities to convey understanding of environmental observations. The paper addresses the technical challenges in the Environmental Usage Area and the need for designing multi-style service oriented architecture. Key topics are the mapping of requirements to capabilities, providing scalability and robustness with implementing context aware information retrieval. Another essential research topic is handling data fusion and model based computation, and the related propagation of information uncertainty. Approaches to security, standardization and harmonization, all essential for sustainable solutions, are summarized from the perspective of the Environmental Usage Area. The paper concludes with an overview of emerging, high impact applications in the environmental areas concerning land ecosystems (biodiversity), air quality (atmospheric conditions) and water ecosystems (marine asset management)

The Limited Effect of Graphic Elements in Video and Augmented Reality on Children’s Listening Comprehension

There is currently significant interest in the use of instructional strategies in learning environments thanks to the emergence of new multimedia systems that combine text, audio, graphics and video, such as augmented reality (AR). In this light, this study compares the effectiveness of AR and video for listening comprehension tasks. The sample consisted of thirty-two elementary school students with different reading comprehension. Firstly, the experience, instructions and objectives were introduced to all the students. Next, they were divided into two groups to perform activities—one group performed an activity involving watching an Educational Video Story of the Laika dog and her Space Journey available by mobile devices app Blue Planet Tales, while the other performed an activity involving the use of AR, whose contents of the same history were visualized by means of the app Augment Sales. Once the activities were completed participants answered a comprehension test. Results (p = 0.180) indicate there are no meaningful differences between the lesson format and test performance. But there are differences between the participants of the AR group according to their reading comprehension level. With respect to the time taken to perform the comprehension test, there is no significant difference between the two groups but there is a difference between participants with a high and low level of comprehension. To conclude SUS (System Usability Scale) questionnaire was used to establish the measure usability for the AR app on a smartphone. An average score of 77.5 out of 100 was obtained in this questionnaire, which indicates that the app has fairly good user-centered design

Media Usage in Post-Secondary Education and Implications for Teaching and Learning

The Web 2.0 has permeated academic life. The use of online information services in post-secondary education has led to dramatic changes in faculty teaching methods as well as in the learning and study behavior of students. At the same time, traditional information media, such as textbooks and printed handouts, still form the basic pillars of teaching and learning. This paper reports the results of a survey about media usage in teaching and learning conducted with Western University students and instructors, highlighting trends in the usage of new and traditional media in higher education by instructors and students. In addition, the survey comprises part of an international research program in which 20 universities from 10 countries are currently participating. Further, the study will hopefully become a part of the ongoing discussion of practices and policies that purport to advance the effective use of media in teaching and learning
