Abstract
A task is to automatically carry out directional control of an antenna in parallel with routing in a radio network. In the event that a radio transmission apparatus, which is a node configuring the radio network, received a routing packetfrom the node over the radio network, it acquires and records a received direction of the routing packet, an identifier of a transmission source node, metric information indicating a route cost, and an identifier of a route destination node, and in the event that the route destination node is not its own node, the radio transmission apparatustakes control so as to match a direction of an antenna systemto the received direction of the node having minimum metric information out of the recorded metric information.
