RT-GRIS, our grid portal, has two purposes. One is effective CPU scavenging and other is supporting a great number of grid node. CPU-scavenging, cycle-scavenging, cycle stealing or shared computing creates a “grid” from the unused resources in a network of participants. It is an important technique for a distribution of grid job and node resource. And, if the grid portal uses fewer resources, those...
The objective of the Seoul ubiquitous (smart) city project was to find a method to measure a temperature, a humidity or a noise level in the urban areas. But the problem was that we would need to install a large number of sensors over a broad area and each sensor must be connected to the center-server through wired or wireless network. To solve this problem, we created the MSU (Moving Sensor Unit)...
In enterprise computing, distribute computing and client/server computing are useful technologies because most companies have so many servers and various computing resource. Moreover, in military or financing computing parts, real-time computing is also useful technology because they need to catch the enemy quickly and they need to trade stock quickly. Fault tolerance assists stabilized system. Self-repair...
In this paper, we introduce an unified ubiquitous middleware which supports an infrastructure to provide the ubiquitous convergence services by providing not only dynamic service discovery based on context-awareness but also variety of converged services in three applications such as environment management, traffic accident management and underground fire accident management. It is composed of three...
