Abstract: In an ad-hoc wireless network, a single multicast message can be used to announce availability of queued data to one or more WLAN devices in the ad-hoc network. A wireless network device in the ad-hoc network can determine network identifiers associated with the other wireless network devices in the ad-hoc network for which the queued data is available. The wireless network device transmits the multicast message, which identifies the wireless network devices for which queued data is available, to indicate the wireless network devices that should remain in an active power state. On receiving the multicast message, a receiving WLAN device can read a network identifier bit associated with the receiving WLAN device to determine whether or not the receiving WLAN device should remain in the active power state. This can reduce transmission overhead and improve power savings, efficiency, and data reliability.

Abstract: In ad-hoc wireless networks, functionality can be implemented to dynamically enable/disable an ad-hoc power save mode depending on whether or not the WLAN device is in a continuous traffic environment. The WLAN devices in the ad-hoc wireless network can use beacon frames to transmit a power mode switch request, to respond to a received power mode switch request (to indicate acceptance or rejection of the received power mode switch request), and to indicate a power mode switch status. The WLAN devices switch the power mode if all the WLAN devices in the ad-hoc wireless network accept the power mode switch request. Changing the power mode depending on the environment can improve power savings, data throughput, and reliability.
