The surveyed control point on land surveying contributes to the performance of accurate measurement of land positions. In this paper, we propose a management system for positioning and indicating the surveyed control point using GPS and RFID. Also for monitoring the status of the surveyed control point, the system sends its location data to the remote control center via the CDMA networks. This system...
WSN (Wireless sensor networks) based on low-power technologies is one of the important technologies currently available in constructing ubiquitous society and is applied in various fields, including, environmental monitoring, disaster management, logistics management, and home network. In this paper, we proposed a WSN-based stable management system as one of the WSN applications. This stable management...
A workflow can weave independent jobs into a chain of work processes, based on a scenario. The uWDL is an XML-based workflow language that can supply web services to users with various contexts that can be dynamically occurring in real world. With the uWDL, users can easily make context-aware workflow services in the various computing environments. In this paper we design and develop a workflow scenario...
Green House is one of the representative models of modern agriculture business. As IT fields develop rapidly we study the methodology of applying IT to agriculture. This paper proposes a Ubiquitous glass Green Houses Management System (U-GHMS) based on USN (Ubiquitous Sensor Network) which can be real-time monitoring and controlling of Green house's facilities by collecting environment and soil information...
Recently, there are many researches to enable future ubiquitous environments based on wireless sensor network (WSN). Various sensing devices deployed in wireless sensor network collect meaningful data from physical environments and the data are delivered to neighbor node through radio interfaces for further processing. The representative application in WSN is a data collecting system, which monitors...
Wireless communication technology and state-of-the-art miniaturization have enabled the wireless sensor network with smart environmental sensors. The sensor network is a new field which has been vigorously researched in the ubiquitous computing and ad hoc network. How efficiently use the limited energy in this USN (ubiquitous sensor network) has been debated. Utilizing the directed diffusion and gossiping...
Recently, the research trend and developmental tendency of ubiquitous computing technologies have been heading in the direction which seamlessly provides the optimum service to users through context- awareness, analogy and networking with various sensor nodes. There is an overwhelming need to develop the USN middleware platforms that have the functions for processing data, monitoring, merged communication...
Plenty of new routing protocols have been presented to overcome the difficulty in applying the routing protocol which was proposed for the existing wireless networks (IEEE 802.11) to WSN. Therefore, this paper presents the wired and wireless integrated networks which transmit the information collected from the wireless sensor networks to wired networks via WSN Gateway. At this time, this paper embodies...
