A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a Base station or sink which communicates the data further for processing. The sensor nodes have limited battery power(More)
In this paper we evaluated an application of creativity techniques with sampling partial data from a large number of idea cards, to reduce operation cost of problem definition or decision-making at critical situation as disasters. In our experiments, we picked up 30 of 60 idea cards randomly, and operated KJ method remotely. We found operation time of the(More)
