A system, apparatus and method for organizing devices in a peer-to-peer communication environment. A number of devices synchronize among themselves and select masters (or synchronization stations) to organize the devices into a hierarchy. Master devices have associated preference values reflecting their preference or suitability to be a master device, and broadcast synchronization frames to keep devices synchronized. When multiple devices in one or more hierarchies execute a common application or service, they form a private group to exchange or share data (e.g., play a game, transfer a file). All devices in the hierarchy maintain and advertise a public or default identifier of the hierarchy, and all devices in the private group maintain and advertise a private identifier specific to the group. Members of the group synchronize under a top group master (or root sync station), which synchronizes with a master that is part of the hierarchy.
