Abstract

A mobile node includes: a status acquiring unit for acquiring status information; and a communication module for transmitting the status information to a mobile management server. The mobile management server includes: an input/output unit for receiving the status information from the mobile node; a management data creating unit for analyzing changes in the distribution of the status information, thereby calculating, as characteristic parts, parts having high distribution densities; and a request processing unit for outputting information about the calculated characteristic part. The management data creating unit includes: a node data registering function for storing the status information; a label calculating function for calculating a label in which the status information is multiplexed; and a characteristic part extracting function for extracting, in descending order of distribution density, characteristic parts representative of parts having high label distribution densities.
