Each node connected to an ad hoc network receives route information from an adjacent node. Each node obtains quality information indicating quality of a route indicated by the route information with respect to the received route information. Each node determines whether a plurality of route information items whose packet destination nodes are the same are received at a predetermined frequency. When it is determined that a plurality of route information items whose packet destination nodes are the same are received, each node compares quality information items of the plurality of received route information items, and selects a route information item corresponding to a quality information item indicating a highest quality as a comparison result. Each node relays the selected route information item to an adjacent node.
