The wireless ubiquitous network and various communication services are expected to be realized. The wireless ubiquitous network is defined as the converged network to integrate the mobile network with the fixed IP based network. First, the concept of wireless ubiquitous network architecture is shown which is based on IMS standardized by 3GPP. Next, Parlay is described as the solution of Open API approach...
Sensor nodes in ubiquitous sensor network (USN) environments are composed of many sensors and hardware components for various purposes and applications, such as service in the industrial field, the public administration sector, and in life services. A middleware is required for wireless sensors to treat a huge amount of information from sensor nodes. However, the use of a middleware and specialized...
With the fast development of wireless sensor networks and context-aware systems, ubiquitous sensor networks (USN) is expected to play a very important role in near future. Businesses with USN and technologies for USN, however, are still far from mature. We address issues concerning technology development, environment creation, and service model for the businesses using USN. We propose a USN business...
Applications in context-aware computing continuously change their operations based on sensor data or services provided by various physical spaces in the real world, such as persons, shops and homes. We propose a gateway framework for physical spaces in this paper, which serves as a middleware platform for context-aware applications to access data from sensor networks deployed in these spaces. The...
We present several implementations of public information collection systems. September 11th tragedy, acts of mass terrorism like DC sniper case, and suicide bombings in Europe force authorities to seek the most effective surveillance technique. It is common consensus that a common bystander does see the potentially dangerous events unwrap, and making it possible for him to notify the appropriate personal...
