WIRED AD HOC NETWORK SYSTEM, POWER SUPPLY CONTROL DEVICE, RELAY NODE DEVICE, AND POWER SUPPLY CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To control power supply from a power supply device to respective relay node devices in a wired ad hoc network system so that the respective relay node devices start normally.SOLUTION: A wired ad hoc network system comprises: a power control device connected to a first power supply device; a relay node device in a basic zone which starts by means of receiving power supply from the first power supply device and supplies power supplied from the first power supply device to an adjacent relay node device according to a frame transmitted from the power control device; and a relay node device in an extended zone adjacent to the basic zone which starts by means of receiving power supply from the first power supply device through a relay node device in the basic zone and supplies power supplied from a second power supply device to an adjacent relay node device in the extended zone according to a frame transmitted from the power control device, where the extended zone includes a relay node device connected to a second power supply device.
