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(More)
Effects of individual petroleum hydrocarbons on the luminescence inhibition of Vibrio fischeri were evaluated according to a standard protocol to develop a quantitative structure-activity relationship and identify the apparent toxicity cutoff. Eighteen aromatic hydrocarbons, including benzene and its derivatives and polycyclic aromatic hydrocarbons (PAHs),(More)
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(More)
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(More)
