Abstract
A wireless communication device acquires membership in a predefined group, joins an ad hoc network associated with the predefined group, and joins and participates in a first session established through an infrastructure device for distributing media to the predefined group. If the wireless communication device is a duplicator node for the ad hoc network, then it receives the media from the infrastructure device and distributes the media other nodes of the ad hoc network, otherwise it receives the media from the duplicator node. The infrastructure device identifies the duplicator node for each ad hoc network associated with the predefined group and each member of the predefined group that is not a node of any of the ad hoc networks and distributes the media only to these members of the predefined group.
