Kind Code:
A1
Abstract:
A control apparatus comprises a communication unit (320), a determination unit (310B) and a sleep instruction unit (310C). The communication unit uses a multi-hop communication among a plurality of nodes including a connected first node and a un-connected second node, and receives information from the first node. The determination unit determines an acceptance date/time of acceptance by the first node of a connection with the second node, on the basis of the battery level of the first node, communication quality between the first node and the second node, power characteristics of the second node, and first environment information related to the environment of the position where the second node is located. The sleep instruction unit sends an instruction to the first node indicating that the first node should be in sleep state until the acceptance date/time.
