Abstract

A method including: receiving, over a first wireless channel, a first beacon specifying a time interval during which a first wireless client is to communicate with a wireless access point according to an infrastructure network model; in response to receiving the first beacon, causing the first wireless client to exchange packets of data with the wireless base station over the first wireless channel for the time interval specified in the first beacon, and in response to expiration of the time interval specified in the first beacon, (i) causing the first wireless client to exchange packets of data with a second wireless client over a second wireless channel according to an ad hoc network model, or (ii) causing the first wireless client to enter a sleep state.

Claims

1. A wireless client comprising:

an infrastructure controller configured to exchange, according to an infrastructure network model, packets of data with a wireless access point over a first wireless channel;

an ad hoc controller configured to exchange, according to an ad hoc network model, packets of data with a second wireless client over a second wireless channel; and

a master controller configured to

in response to the wireless client receiving a first beacon specifying a time interval during which the wireless client is to communicate with the wireless access point according to the infrastructure network model, cause the infrastructure controller to exchange packets of data with the wireless access point over the first wireless channel for the time interval specified in the first beacon, and

in response to expiration of the time interval specified in the first beacon,

(i) cause the ad hoc controller to exchange packets of data with the second wireless client over the second wireless channel, or

(ii) cause the wireless client to enter a sleep state.

2. The wireless client of claim 1, wherein the first beacon comprises a channel access time value, and wherein the channel access time value specifies the time interval during which the wireless client is to communicate with the wireless access point according to the infrastructure network model.

3. The wireless client of claim 1, wherein the master controller is further configured to cause the ad hoc controller to exchange packets of data with the second wireless client over the second wireless channel in response to the wireless client receiving a second beacon, wherein the second beacon is transmitted subsequent to the first beacon.

4. The wireless client of claim 3, wherein the second beacon specifies a time interval during which the wireless client is to communicate with the second wireless client according to the ad hoc network model.

5. The wireless client of claim 1, wherein each of the infrastructure network model and the ad hoc network model is compliant with IEEE standard 802.11.

6. A method comprising:

receiving, over a first wireless channel, a first beacon specifying a time interval during which a first wireless client is to communicate with a wireless access point according to an infrastructure network model;

in response to receiving the first beacon, causing the first wireless client to exchange packets of data with the wireless access point over the first wireless channel for the time interval specified in the first beacon; and

in response to expiration of the time interval specified in the first beacon,

(i) causing the first wireless client to exchange packets of data with a second wireless client over a second wireless channel according to an ad hoc network model, or

(ii) causing the first wireless client to enter a sleep state.

7. The method of claim 6, wherein the first beacon comprises a channel access time value, and wherein the channel access time value specifies the time interval during which the first wireless client is to communicate with the wireless access point according to the infrastructure network model.

8. The method of claim 6, wherein causing the first wireless client to exchange packets of data with the second wireless client over the second wireless channel comprises:

exchanging packets of data with the second wireless client over the second wireless channel according to the ad hoc network model in response to the first wireless client receiving a second beacon, wherein the second beacon is transmitted subsequent to the first beacon.

9. The method of claim 8, wherein the second beacon specifies a time interval during which the first wireless client is to communicate with the second wireless client according to the ad hoc network model.

10. The method of claim 6, wherein each of the infrastructure network model and the ad hoc network model is compliant with IEEE standard 802.11.
