Abstract
To reduce the power consumption of a wireless communication hardware device, power conservation scheduling algorithms can be implemented. Reoccurring events, including DTIM intervals and listen intervals can be scheduled as awake times. Similarly expected response intervals can be scheduled as awake times based on information, such as round trip time, that can be passed together with data to be transmitted. The wireless communication hardware device can be placed into a doze state unless it is transmitting data, or unless it is expecting a transmission during one of the scheduled awake times.
