The communication cost calculation unit 4 calculates the communication cost from the received information, and
ii'3 Send to selection section 3. The relay path selection section 3 identifies all routes I, causes the communication cost calculation section 4 to calculate the communication cost for each, and sends the most economical transmission path to the message transmission/reception control section 2.
