Patent ID: 8817682

Claim:
A node device, comprising: a first communication interface configured to communicate data over an ad-hoc wireless local-area-network (WLAN) via a first communication channel, the ad-hoc WLAN including peer devices of a first basic service set; a second communication interface configured to communicate other data over an infrastructure WLAN via a second communication channel, the infrastructure WLAN including other node devices of a second basic service set; a channel switch configured to switch between the first communication channel for communicating the data over the ad-hoc WLAN and the second communication channel for communicating the other data over the infrastructure WLAN; and a power save service configured to: determine a time synchronization function (TSF) offset based on a TSF value associated with the ad-hoc WLAN and a TSF value associated with the infrastructure WLAN; and transmit, based at least in part on the TSF offset, a notification to one of the basic service sets, the notification indicating that the node device is entering a power save mode to facilitate communication with another of the basic service sets.
