A Wi-Fi Direct Group Owner stores network parameters needed for proper operation of a peer-to-peer network. These include the network name and identifier, the power save schedule, the security settings, MAC address of all of the group members, etc. To reduce the need for a single Group Owner, this information is distributed. As each new device is added to the network, all of these parameters are passed via IEEE 802.11 data packets from the device acting as the Group Owner to the new peer device. This way, the new peer device has all of the information about the group at the time that it joins. Any device in the Resilient Peer Network can temporarily take on the role of a traditional Wi-Fi Direct Group Owner (admission control). Selection of which peer will act as a Group Owner will depend on a user action or network event.

A multimedia data distribution system is provided. The multimedia data distribution system comprises a multimedia controller and at least a distribution zone. A distribution zone has a zone hub and zero to finite number of zone media player. The zone hub receives multimedia data from a multimedia content source through an out-of-zone data path and then synchronously redistributes multimedia contents to rest of zone media players via in-zone data paths. A multimedia controller utilizes out-of-zone control path to transmit control message to a zone hub, which in turn relays the control messages to addressed zone media player(s) via in-zone control paths. The zone hub of a distribution zone receives status updates from individual zone media players via in-zone status update paths, aggregates them, and then relays to the multimedia controller via the out-of-zone status update path. While out-of-zone data, control, and status update paths are setting up based on Wi-Fi connections to an infrastructure AP or a Hotspot, all of the in-zone paths are established on Wi-Fi Direct peer-to-peer connections.
