Abstract: This control system comprises a shared information reception unit and a control unit. The shared information reception unit receives destination information indicating a destination, permission/prohibition information indicating whether to permit or prohibit disclosure to parties other than the destination, and shared information. The control unit controls whether to disclose the shared information. Upon receiving a request to disclose the shared information from a requesting party other than the destination, the control unit allows the shared information to be disclosed to the requesting party if the disclosure is permitted, or prohibits the shared information from being disclosed to the requesting party if the disclosure is prohibited.

Abstract: In the present invention, a wireless communication network includes a plurality of nodes which can form P2P (peer-to-peer) groups and are capable of performing wireless communications using a first communication method and wireless communications using a second communication method. A first owner node (GO node) that operates as a first P2P group access point transmits a message for requesting delivery node connection preparations to a second GO node that operates as a second P2P group access point present in a neighborhood by wireless communication using the second communication method, and selects, as a delivery node, one or a plurality of client nodes belonging to the first P2P group. The delivery node is disconnected from the first P2P group and is connected to the second P2P group, and information is transferred between the delivery node and the second GO node.
