Claim 0:
1. A method of detecting an anomaly of a road side unit, which is performed by an anomaly detecting apparatus interworking with one or more road side units, the method comprising:
receiving traffic data from each of the one or more road side units;
calculating a distance between the one or more road side units based on the traffic data;
grouping the road side units with the distance, which is less than or equal to a preset value, among the one or more road side units into the same group;
calculating all subsets of groups of the road side units, which are grouped according to the grouping;
generating input data of an artificial neural network from subsets among all the subsets of the groups, to which a first road side unit among the one or more road side units belongs;
generating output data of the artificial neural network based on the input data; and
detecting an anomaly of the first road side unit based on the output data.
