COMMUNICATION DEVICE, RADIO NETWORK SYSTEM, RADIO NETWORK CONTROL METHOD, AND RADIO NETWORK CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To timely optimize a path used by a radio communication terminal in a radio network system using a multi-hop method.SOLUTION: A radio network system is composed of a plurality of aggregation devices and a plurality of communication devices. Each of the plurality of communication devices is connected to any one of the plurality of aggregation devices by using multi-hop radio communication. The communication device calculates a first evaluation value showing the degree of easiness of connection with an aggregation device currently connected with the communication device, for each of a plurality of paths to the aggregation device which include a first path used currently, on the basis of situations of the paths on the evaluation; and connects with the aggregation device by using a second path whose first evaluation value is the highest in place of the first path when the first path's first evaluation value is not the highest.
