20080212604 | SYSTEMS AND METHODS FOR CONTENTION CONTROL IN WIRELESS NETWORKS - Systems and methods provide for controlling contention in a wireless network device. The systems and methods transmit a packet on a wireless network. If the transmission is not successful, then a contention window parameter is adjusted according to a fast backoff operation. If the packet transmission was successful and the current value of the contention window parameter is less than a threshold value then the contention window parameter is decreased according to a contention avoidance operation. If the packet transmission is successful and the current value of the contention window parameter is greater than the threshold value then the contention window parameter is decreased according to a slow start operation. | 09-04-2008 |
20080234012 | Scheduling for power savings in a wireless network - In a wireless network, a wireless device may dynamically estimate how long it can remain in a sleep mode without missing out on a necessary opportunities to communicate within the network. In some embodiments, this estimate may be based on a combination of things such as the amount of data still queued up for transmission, recent history on data rates, a prediction on how long it will take another device (e.g., an access point) to accumulate enough data for another transmission, and/or how long the queued-up data can wait before it becomes stale. | 09-25-2008 |
