| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In an argument about the possibility of communication with cognitive radio, data to discuss the utilization of radio waves is absolutely imperative. Thus, we are working on development of a system which enables to recognize spectrum utilization intuitively by collecting spectrum data and visualizing its spatiotemporal variation on a map. There was an obstacle, however, that a delay of communication between servers which occured in visualization processes prevented smooth browsing. In this paper, we implemented a method of reducing this communication by aggregating data files and references of meta data and evaluated association between a spectrum data size and processing time. At last, it was shown that this method improved the visualization process of our system. | |
