Document Type and Number:
WIPO Patent Application WO/2019/008707
Kind Code:
A1
Abstract:
A control device for a wireless network including a group of wireless nodes that each receive and are driven by electrical power from at least one of an energy harvesting unit and a storage battery, and that each operate in a first state, in which a connection process with a connection request source is performed in response to a connection request, and a second state, in which the remaining charge of the storage battery can be replenished by the energy harvesting unit and connection requests are not responded to. The control device for a wireless network stores, for each wireless node, a remaining charge value for the storage battery, a communication quality value for communication with another wireless node in the vicinity, and information indicating either the first or the second state, and when a disconnected node is detected, the control device specifies a wireless node in the second state, said wireless node having a remaining charge value and a communication quality value for communication with the disconnected node that surpass respective threshold values, and transmits instructions to change the specified wireless node in the second state to the first state, in which the connection process with the disconnected node is performed.
