A communication control method to be executed by a communication device, includes: transmitting, to one or more communication devices coupled to the communication device, a packet in which a destination is set; and determining, based on the number of paths that are among paths extending through the one or more communication devices to the destination and through which a response to the packet is received from the destination, the number of times of retransmission in the transmission of another packet to the destination.

Communication control method, network system, and communication device

A node transmits a route search demand, which is a demand to search for a route from the node to a predetermined device among adjacent communication devices, to an adjacent communication device that is not selected as a transmission destination of the route search demand. The node transmits the route search demand when the number of adjacent communication devices serving as confirmed routes is smaller than a predetermined number and when there is an adjacent communication device that has not been selected. The node stops transmission of the route search demand when the number of the adjacent communication devices serving as the confirmed routes reaches the predetermined number. The node transmits a warning to the predetermined device when the number of the adjacent communication devices serving as the confirmed routes is smaller than the predetermined number and when there is no adjacent communication device that has not been selected.
