EFFICIENT CELLULAR RADIO ACCESS MANAGEMENT FOR MOBILE COMPUTING DEVICES
Next generation cellular radios are being developed that facilitate higher (compared to legacy cellular radios) bandwidth, lower latency, etc. While mobile computing devices may include the next generation cellular radios, deployment of next generation cellular base stations that provide full next generation support is sparse. As such next generation cellular radios have only recently been introduced, the next generation cellular radios have not been subjected to extensive power optimization, resulting in significant power consumption (particularly when not connected to the sparsely deployed next generation cellular base stations). Techniques described in this disclosure enable efficient cellular radio access management for mobile computing devices in which the mobile computing devices actively enable and disable the next generation cellular radio based on a proximity to the next generation cellular base stations (or, in other words, geofencing)

Health and mobility: Current status and future paradigms
The movement of telemedicine to the wireless and mobile Internetable applications is imminent in the next few years. This migration from the desktop platforms to the wireless and mobile configurations will have significant impact on the future health care delivery system and their globalisation. The recent telecommunications and biomedical computing advances will significantly enhance the current methodologies of telemedicine and telecare systems. This editorial will present some of the evolutionary issues and important aspects that have to be considered in the developing technologies for the next generation of Internet and Third Generation of Mobile Systems (3G), geared for future telemedical applications. These will provide new dimensions to existing medical services and areas of outreach, that are not possible in the current generation and will have tremendous impact on how the health care delivery will be shaped for the 21 Century
Next Generation Middleware Technology for Mobile Computing
Current advances in portable devices, wireless technologies, and distributed systems have created a mobile computing environment that is characterized by a large scale of dynamism. Diversities in network connectivity, platform capability, and resource availability can significantly affect the application performance. Traditional middleware systems are not prepared to offer proper support for addressing the dynamic aspects of mobile systems. Modern distributed applications need a middleware that is capable of adapting to environment changes and that supports the required level of quality of service. This paper represents the experience of several research projects related to next generation middleware systems. We first indicate the major challenges in mobile computing systems and try to identify the main requirements for mobile middleware systems. The different categories of mobile middleware technologies are reviewed and their strength and weakness are analyzed

The Next Generation of Mobile Computing for Hospitals
Mobile computing in the broadest sense is when multiple communications devices work together within an environment, unhampered by equipment limitations, distance, or interference. As computer and networking devices are put into smaller and smaller envelopes, their workplace usefulness increases. These mobile devices offer the potential of increasing the quality of healthcare services by making better use of hospital resources, including improved communications among medical and support staff, and increased patient monitoring. This paper depicts several hospital scenarios in order to conceptualize the planning and design of future mobile networks, taking into consideration patient care, management thinking, and technical issues
C-Arc: A Novel Architecture for Next Generation Context- Aware Systems
Computing is becoming increasingly mobile and ubiquitous. This implies that applications and services must be aware and adapt to highly dynamic environments. However, building contextaware mobile services is currently a complex and time consuming task. The emergence of truly ubiquitous computing, enabled by the availability of mobile and heterogeneous devices and an increasing number of commercial off-the-shelf sensing technologies, is hampered by the lack of standard architectural support for the development of context-aware systems. In this paper, the common architecture principles of context-aware systems are presented and the crucial contextaware architecture issues to support the next generation context-aware systems which will enable seamless service provisioning in heterogeneous, dynamically varying computing and communication environments are identified and discussed. Furthermore, a novel architecture, CArc,is proposed to aid in the development of the next generation context-aware systems. A prototype implemented of C-Arc is also presented to demonstrate the architecture. C-Arc provides support for most of the tasks involved in dealing with context, namely acquiring context from various sources, interpreting context and disseminating context.Keywords: Context-aware architecture, context-aware systems, context-aware mobile services,mobile and ubiquitous computing
