Future challenges and recommendations

Rapid advances in information technology and telecommunications, and in particular mobile and wireless communications, converge towards the emergence of a new type of “infostructure” that has the potential of supporting a large spectrum of advanced services for healthcare and health. Currently the ICT community produces a great effort to drill down from the vision and the promises of wireless and mobile technologies and provide practical application solutions. Research and development include data gathering and omni-directional transfer of vital information, integration of human machine interface technology into handheld devices and personal applications, security and interoperability of date and integration with hospital legacy systems and electronic patient record. The ongoing evolution of wireless technology and mobile device capabilities is changing the way healthcare providers interact with information technologies. The growth and acceptance of mobile information technology at the point of care, coupled with the promise and convenience of data on demand, creates opportunities for enhanced patient care and safety. The developments presented in this section demonstrate clearly the innovation aspects and trends towards user oriented applications

Bluetooth Wireless Technology: A milestone in ICT

This article summarizes the Bluetooth technology – a type of Wireless Personal Area Network (WPAN) with emphasis on the pivotal role of Bluetooth enabled devices in ICT. The areas of application of Bluetooth technology, itssecurity, basic design and architecture, and likely future trends in its applications are also discussed with a view to highlighting its major significance. Bluetooth was compared with other wireless communications technologies specifically Infrared Data Association (IrDA) and Wireless Fidelity (Wi-Fi®) showing their dissimilarities and, above all, the advantages of Bluetooth wireless protocol over the other wireless technologies which have made it a topic of discourse in ICT are discussed

The Future of Mobile Industry

This paper discusses the future of mobile industry along with some of the background leading to the emergence of wireless technology. First, it gives an overview of today’s telecommunication network and the major differences between fixed wired networks and wireless networks. The discussion then focuses on the challenges facing the wireless industry and the way out through aggressive innovation by employing Wireless Intelligence Network (WIN) technology. The paper also discusses some important trends in wireless industry and the customers expectations which are also part of the challenges for the mobile industry. Finally particular reference is made to the developing nations especially Nigeria in the ongoing trends in mobile communication industry

Teensites.com: A Field Guide to the New Digital Landscape

A 2001 report from the Center for Media Education, provided here as background to work produced by Kathryn Montgomery after coming to American University and CSM (see http://www.centerforsocialmedia.org/resources/publications/ecitizens/index2.htm -- Youth as E-Citizens'), surveys the burgeoning digital media culture directed at -- and in some cases created by -- teens.This report surveys the burgeoning new media culture directed at -- and in some cases created by -- teens. TeenSites.com -- A Field Guide to the New Digital Landscape examines the uniquely interactive nature of the new media, and explores the ways in which teens are at once shaping and being shaped by the electronic culture that surrounds them

Building Programmable Wireless Networks: An Architectural Survey

In recent times, there have been a lot of efforts for improving the ossified Internet architecture in a bid to sustain unstinted growth and innovation. A major reason for the perceived architectural ossification is the lack of ability to program the network as a system. This situation has resulted partly from historical decisions in the original Internet design which emphasized decentralized network operations through co-located data and control planes on each network device. The situation for wireless networks is no different resulting in a lot of complexity and a plethora of largely incompatible wireless technologies. The emergence of "programmable wireless networks", that allow greater flexibility, ease of management and configurability, is a step in the right direction to overcome the aforementioned shortcomings of the wireless networks. In this paper, we provide a broad overview of the architectures proposed in literature for building programmable wireless networks focusing primarily on three popular techniques, i.e., software defined networks, cognitive radio networks, and virtualized networks. This survey is a self-contained tutorial on these techniques and its applications. We also discuss the opportunities and challenges in building next-generation programmable wireless networks and identify open research issues and future research directions.Comment: 19 page

A distributed directory scheme for information access in mobile computers

In this paper, we discuss the design aspects of a dynamic distributed directory scheme (DDS) to facilitate efficient and transparent access to information files in mobile environments. The proposed directory interface enables users of mobile computers to view a distributed file system on a network of computers as a globally shared file system. In order to counter some of the limitations of wireless communications, we propose improvised invalidation schemes that avoid false sharing and ensure uninterrupted usage under disconnected and low bandwidth conditions
