Events are crammed with numerous basic elements in today’s management and manufacturing system. Especially, for a large-scale system, there are thousands of independent messages (events) happening every second. How to integrate the information and how to deal with such massive events are faced by most of the system. Event monitoring and processing has been posed in manufacturing corporations to tackle this challenge. However, well-prepared methodology and processing are lack for this challenge. In this article, we propose an extensible event-driven manufacturing platform for handling those massive events. First, holistic architecture of the platform is depicted. Next, the principle of primitive and complex event is detailed. Eventually, Complex Event Processing (CEP) approach is applied to the platform.

Health monitoring is repeatedly mentioned as one of the main application areas for Pervasive computing. Mobile Health Care is the integration of mobile computing and health monitoring. It is the application of mobile computing technologies for improving communication among patients, physicians, and other health care workers. As mobile devices have become an inseparable part of our life it can integrate health care more seamlessly to our everyday life. It enables the delivery of accurate medical information anytime anywhere by means of mobile devices. Recent technological advances in sensors, low-power integrated circuits, and wireless communications have enabled the design of low-cost, miniature, lightweight and intelligent bio-sensor nodes. These nodes, capable of sensing, processing, and communicating one or more vital signs, can be seamlessly integrated into wireless personal or body area networks for mobile health monitoring. In this paper we present Intelligent Mobile Health Monitoring System (IMHMS), which can provide medical feedback to the patients through mobile devices based on the biomedical and environmental data collected by deployed sensors.

This paper addresses multiple input multiple output (MIMO) techniques within 3G WCDMA. It begins with an overview of MIMO theory and presents WCDMA physical layer and recent high speed downlink packet access (HSDPA) enhancement to the WCDMA standard. Furthermore, MIMO channel models used in WCDMA performance evaluation were also discussed. The distance between base stations is of little influence on capacity loss of TD-SCDMA uplinks, while the capacity loss of WCDMA uplinks will increase as the distance between base stations increases. The uplinks of WCDMA are of little interference to the downlinks of TD-SCDMA, which can even be ignored. The capacity loss of WCDMA uplinks will increase as the distance between base stations increases. To ensure that the capacity loss of WCDMA system is less than 5% at any offset distance, the ACIR should exceed 50dB. This paper presents methods for evaluating radio wave propagation, especially for cases where the base station antenna is below the rooftops, i.e. in the case of microcellular network environments. The developed microcellular propagation model has been developed for network planning purposes and it has been verified using numerous field propagation measurements, since there is often a gap between theory and practical implementation, prototyping is used to study the effects of real propagation channels, non-ideal RF equipment, and to understand complexity/speed/precision tradeoffs in algorithm implementation.

Recently, through the development of the mobile network, a user was offered various services. The SDR technology is accessible to various mobile networks in the environment. In various wireless network services such as the ubiquitous and Convergence environment, it can provide the user an optimum radio environment. It is acceptable the various services like this as the SDR terminal of one through the Waveform Application, and more developed wireless network technique is applicable. Particularly, the processing speed of a processor developed exponentially with the growth of the semi-conductor technology. Furthermore, as the conversion technique between the digital signal and the analog signal developed rapidity, the introduction of SDR was available in the high speed data transfer system including 3rd generation wireless internet service. It has to be seamless vertical handover executable so that the SDR terminal can provide internet access service in which it is various to a user. In this research, we propose a method for supporting the Seamless VHO in the SDR terminal and the VHO-SCA for interoperate a SDR Middleware and IEEE 802.21 MIH.
