Abstract
Symmetrical and asymmetrical ad-hoc, wireless networks and a method for saving power in the same may include causing a first station to determine whether a second station has a master capability to buffer data traffic for the first station. A first station requests the second station to buffer the data traffic intended for the first station for a first predetermined period. The first station enters a first power save mode, and the second station buffers the data traffic for the first station for the first predetermined period. The first station exits the first power save mode after the first predetermined period and the second station sends the buffered data traffic to the first station. Both the first and second stations may have master capabilities, or only one of the first and second stations may have a master capability.

2. A method for saving power in an ad-hoc network including a first station and a second station, wherein each of the first station and the second station has a corresponding network interface configured to wirelessly communicate with other stations in the ad-hoc network, the method comprising:
-
transmitting, from the first station, an advertisement of a capability of the first station to buffer data traffic intended for other stations in the ad-hoc network; responsive to transmitting the advertisement of the capability of the first station to buffer data traffic intended for other stations in the ad-hoc network, receiving, at the first station, a request to buffer data traffic intended for the second station for a time period; and responsive to receiving the request at the first station, transmitting, from the first station, a response to the request, wherein the response acknowledges acceptance of the request, buffering, at the first station, data traffic intended for the second station, and subsequent to buffering the data traffic intended for the second station, transmitting, from the first station to the second station, the buffered data traffic intended for the second station. - View Dependent Claims (3, 4, 5, 6, 7, 8)

9. A first station for use in an ad-hoc network, the first station comprising:
a network interface, wherein the network interface is configured to; transmit an advertisement of a capability of the first station to buffer data traffic intended for other stations in the ad-hoc network, responsive to transmitting the advertisement of the capability of the first station to buffer data traffic intended for other stations in the ad-hoc network, receive a request to buffer data traffic intended for a second station for a time period; and responsive to receiving the request at the first station, transmit a response to the request, wherein the response acknowledges acceptance of the request, buffer data traffic intended for the second station, and subsequent to buffering the data traffic intended for the second station, transmit the buffered data traffic intended for the second station. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for saving power in an ad-hoc network including a first station and a second station, wherein each of the first station and the second station has a corresponding network interface configured to wirelessly communicate with other stations in the ad-hoc network, the method comprising:
-
receiving, at the first station, an advertisement of a capability of the second station to buffer data traffic intended for other stations in the ad-hoc network; responsive to receiving the advertisement of the capability of the second station to buffer data traffic intended for other stations in the ad-hoc network, transmitting, from the first station, a first request to buffer data traffic intended for the first station for a first time period; and responsive to transmitting the first request at the first station, receiving, at the first station, a response to the first request, wherein the response acknowledges acceptance of the first request, causing the first station to enter a power save mode, and subsequent to buffering the data traffic intended for the first station, receiving, at the first station, the buffered data traffic intended for the first station after exiting the power save mode. - View Dependent Claims (16, 17, 18, 19, 20)

21. A first station for use in an ad-hoc network, the first station comprising:
a network interface, wherein the network interface is configured to; receive, from a second station, an advertisement of a capability of the second station to buffer data traffic intended for other stations in the ad-hoc network, responsive to receiving the advertisement of the capability of the second station to buffer data traffic intended for other stations in the ad-hoc network, transmit a first request to the second station to buffer data traffic intended for the first station for a first time period, responsive to transmitting the first request at the first station, receive, from the second station, a response to the request, wherein the response acknowledges acceptance of the first request, and cause the first station to enter a power save mode, and subsequent to buffering the data traffic intended for the first station, receive the buffered data traffic intended for the first station after exiting the power save mode. - View Dependent Claims (22, 23, 24, 25, 26)
