Abrégé

A control signal used for selecting a parent node in a tree route is transmitted from a first wireless node (#0) among a plurality of wireless nodes (#0-#7) which constitute a backhaul network (9). Second wireless nodes (#1-#7) each select, as a parent node, one of transmission source nodes of a plurality of control signals on the basis of an index indicating the radio wave propagation quality of a route through which each of the control signals received from different route has been propagated. Fixed wireless nodes (#1-#3 and #5-#7) among the second wireless nodes (#1-#7) each transmit the received control signal to the other second wireless nodes, and a movable wireless node (#4) among the second wireless nodes (#1-#7) terminates the received control signal.
