Abstract
A group of computing devices use a wireless channel for communication, resulting in congestion. Within that group, some devices may need to exchange time sensitive application data, such as data indicative of control inputs received from a user. A destination device may transmit a clear to send (CTS) frame over the channel that indicates a CTS interval indicative of a time to suspend transmission. Other computing devices respond to the CTS frame by suspending transmission for the specified CTS interval. However, a source device in the group of many computing devices receives the CTS frame and initiates transmission of application data instead of suspending transmission. As a result, the source device transmits while other computing devices are not transmitting. In some implementations a beacon frame may be transmitted before a CTS frame. The destination device may confirm receipt of the application data by transmitting an acknowledgement to the source device.
