Abstract
Described are techniques for configuring a group of devices to distribute and receive data in a manner that reduces consumption of network resources. A larger group of devices may be divided into subsets of devices, each subset including a master device that provides data to multiple slave devices via a multicast transmission. A master device may be determined based on the respective signal quality between the audio devices and an access point, and the number of other audio devices to which each respective audio device may provide data. Other devices having respective signal quality for communication with the master device that exceeds a threshold may be designated as slave devices. Once a first subset is formed, the remaining devices may be grouped into additional subsets. Remaining devices that are not a part of any subset may receive data via communication with an access point.
