The Method of Generating the Thematic Graph Using the Geosensor Data Stream

摘要

Graph-based statistical analysis is utilized in many areas. To draw a graph based on collected data, data must first be collected. The most general method for this involves the calculation of the average. The sensor position and measuring time change continuously, however, during data collection through the mobile devices in the USN mobile environment. If data with such characteristics are processed simply by calculating their arithmetic averages, past data can be used to represent the current situation. In this paper, a calculation method that considers the time factors is presented to meet the aforementioned challenge.
