PROBLEM TO BE SOLVED: To prevent an unused relay device from occurring.SOLUTION: A communication system according to an embodiment includes a control source device 50, a control destination device 100, and a relay device 200. The control destination device 100 transmits radio wave intensity information to the control source device 50 while pulling the relay device 200. If the radio intensity has lowered, the control destination device 100 disconnects the relay device, forms an ad-hoc network to relay the disconnected relay device, and resumes movement. If there is a relay device 200 not effectively used, the control destination device 100 notifies the relay device 200 of movement history information on the control destination device 100, and moves the relay device 200 to the position of the control destination device 100. The control destination device 100 reconnects the moved relay device and repeats the above process.SELECTED DRAWING: Figure 1 |
