Mobile and Wireless Information Systems: Applications, Networks, and Research Problems

Mobile and Wireless Information Systems received considerable interest in research and development communities. As a result, significant advances were made, which will affect our life both as users and researchers of mobile and wireless technologies. In this paper, we discuss both the current state of mobile and wireless information systems and the challenges in the wide-scale deployment and use of these systems. In particular, we address applications, wireless networks, mobile payments, security, challenges and research problems

UNDERSTANDING THE DETERMINANTS OF ICTS DIFFUSSION IN ECOWAS

The Information and Communication technology(ICT) environment in the economic community of west african states(ECOWAS) has changed sufficiently to warrant re-conceptualization of the earlier initiatives. Notably, many new technologies have emerged, especially in the area of wireless communications. Thus, ECOWAS ability to participate in and enhance its international competitiveness in the new global economy and hence make progress in poverty reduction depends in large part on its ability to use and adapt new information and technological innovations. This project therefore, sets out to enhance understanding and knowledge of the innovative effects of ICT poverty reduction and human development; and to improve ECOWAS capacities to formulate and implement national ICT policies that promote equitable access to ICT and information for socio-economic development.Technological progress, growth, productivity, diffusion, ICTS, AFRICAN ECONOMIES, DYNAMIC PANEL DATA

Supporting Quality-Of-Service of Mobile Commerce Transactions

With the deployment of 3G and 4G mobile networks, a sizable proportion of e-commerce traffic is expected to move to these networks. These transactions are likely to be diverse. Mobile transactions can include unique requirements such as atomicity (all or none steps), push or pull, security, and privacy. Because users are mobile, unpredictable link characteristics, and other problems associated with wireless networks, some mobile commerce transactions may not be completed causing significant annoyance to the users affected. Therefore, the probability of completing mobile transactions is an important parameter for measuring quality-of-service of a network supporting mobile commerce. The transaction completion probability measures the ability of networks to support completion of transactions. This research focuses on improving the support of mobile commerce transactions by the underlying wireless networks. Mobile commerce traffic is classified as messaging, information connectivity, and transactions in order to provide efficient quality-of-service to various applications. This paper introduces the use of priority, sociability and delegation to improve the transaction completion in wireless networks

A feasibility study of an in-the-wild experimental public access WiFi network

Universal Internet access has become critical to modern life, leading to many explorations of approaches to increase its availability. In this paper we report on a study of one such approach, PAWS, that seeks to understand the technical and social constraints of providing Internet access, free at the point of use, by sharing existing broadband subscribers' connections. We elaborate the technical and social context of our deployment, a deprived neighbourhood in a medium-sized British city, and discuss the constraints on and resulting architecture of this system, including the authentication and security mechanisms necessary for a service of this kind. We then report on the use of our deployment over a period of seven months from July 2013 to February 2014, including analyses of the performance and usage of the network. Our data show that PAWS is socially and technically feasible and has the potential to provide Internet access economically to many who are currently digitally disenfranchised. However, doing so requires overcoming numerous challenges, both technical and socia

Prospects of Mobile Search

Search faces (at least) two major challenges. One is to improve efficiency of retrieving relevant content for all digital formats (images, audio, video, 3D shapes, etc). The second is making relevant information retrievable in a range of platforms, particularly in high diffusion ones as mobiles. The two challenges are interrelated but distinct. This report aims at assessing the potential of future Mobile Search. Two broad groups of search-based applications can be identified. The first one is the adaptation and emulation of web search processes and services to the mobile environment. The second one is services exploiting the unique features of the mobile devices and the mobile environments. Examples of these context-aware services include location-based services or interfacing to the internet of things (RFID networks). The report starts by providing an introduction to mobile search. It highlights differences and commonalities with search technologies on other platforms (Chapter 1). Chapter 2 is devoted to the supply side of mobile search markets. It describes mobile markets, presents key figures and gives an outline of main business models and players. Chapter 3 is dedicated to the demand side of the market. It studies users¿ acceptance and demand using the results on a case study in Sweden. Chapter 4 presents emerging trends in technology and markets that could shape mobile search. It is the author's view after discussing with many experts. One input to this discussion was the analysis of on forward-looking scenarios for mobile developed by the authors (Chapter 5). Experts were asked to evaluate these scenarios. Another input was a questionnaire to which 61 experts responded. Drivers, barriers and enablers for mobile search have been synthesised into SWOT analysis. The report concludes with some policy recommendations in view of the likely socio-economic implications of mobile search in Europe.JRC.DG.J.4-Information Societ
