<P>PROBLEM TO BE SOLVED: To perform address management capable of improving processing efficiency in an application level. <P>SOLUTION: A radio communication system 60 includes: distribution nodes (sensor units 21-24) automatically constituting an ad hoc radio network and having radio communication terminals 31-34; and a management node (a sensor network management server 40) managing the ad hoc radio network. The management node includes an address DB 46 for storing an address management table where address groups respectively assigned to the distribution nodes are registered. When receiving data which presents a network address within the address group assigned to the own node from the distribution node, the management node confirms whether the presented address is normal or not by referring to the address management table. Then, an address transmission request is transmitted to all the distribution nodes in accordance with the determination of abnormality, thereby to update the address management table. <P>COPYRIGHT: (C)2013,JPO&INPIT |
