Abstract:
1. A communication device comprising: a memory; and a processor connected to the memory, wherein the processor executes a process including: first transmitting a route search demand, the route search demand being a demand to search for a route from the communication device to a predetermined device among adjacent communication devices that communicate directly with the communication device, to an adjacent communication device that is not selected as a transmission destination of the route search demand; receiving a response to the route search demand transmitted at the first transmitting from the predetermined device; second transmitting the route search demand when the response is received, and 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; stopping transmission of the route search demand when the response is received and when the number of the adjacent communication devices serving as the confirmed routes reaches the predetermined number; and third transmitting 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 communication device that has not been selected.
