In a radio communication system, a relay route is established with a plurality of wireless devices constructing an MPR set for a wireless device as a root node by transmission and reception of a Hello packet. A wireless device other than that constructing the MPR set transmits neighboring wireless device information, information of a neighboring wireless device thereof, to the wireless device as the root node via the relay route. Based on the neighboring wireless device information received via the relay route, the wireless device as the root node generates and stores topology information indicating a topology of a plurality of wireless devices constructing the radio communication system. The wireless device as the root node transmits the topology information to a plurality of wireless devices on a regular basis, or transmits to a wireless device requiring the topology information. As a result, radio communication can be performed with reduced overhead.
