PROBLEM TO BE SOLVED: To perform stable radio communication while securing a stable route by efficiently updating a routing table even when a radio station frequently moves. SOLUTION: In the wireless network for performing packet communication among respective radio stations, on the basis of a signal from an adjacent radio station containing the measured value of a signal-to-interference-noise ratio (SINR) when each of adjacent radio station receives a signal from a present station, the SINR watched from each of adjacent radio station for each azimuth in a horizontal plane with the present station as a center is found, the maximum SINR is selected for each adjacent radio station and defined as a degree of affinity, an adjacent link state table containing the relevant degree of affinity is generated, and an updating signal containing this table is transmitted and exchanged with each of other radio stations so that a global link state table containing the information of the adjacent link state table for each of relevant radio stations can be saved. On the basis of the global link state table, the route from a transmitting source radio station to a destination radio station is selected and a packet signal is routed. |
