Roll-call channel access

Abstract:

Embodiments include a method, computer program product, and system for grouping electronic devices into roll-call channel access (RCCA) groups to reduce the number of devices contending for a wireless channel. Devices within RCCA groups are represented a host device during a channel contention process. Once a channel is granted access to a host device, its respective RCCA group has control of the channel for a predetermined period of time during which devices of the RCCA group take turns transmitting data on the channel.
