Abstract
A radio communication anomaly detecting method includes: gathering and storing different kinds of parameters indicating a radio quality with a sensor node in a storage unit; classifying parameter sets, each containing specific kinds of parameters gathered during a prescribed time period among the stored parameters, into clusters; estimating that a rapid radio quality degradation has occurred during the prescribed time period when there is a cluster of which all average values of specified kinds of parameters among the different kinds of parameters degrade more than those of another cluster; and performing a trend analysis for a time period during which it is not estimated that the rapid radio quality degradation has occurred to determine whether each of the different kinds of parameters gathered during the time period exhibits a trend of degradation, and estimating that a slow radio quality degradation has occurred based on a result of the trend analysis.
