摘要： The duration of receiver on-times may be minimized by sensing and reacting to communication channel power levels at intervals. When no energy is detected on the communication channel, then the receiver may be turned off for a channel sampling interval. If energy is detected on the channel, then the receiver may remain on to determine if a received message is associated with the device. Receiver on-time may also be minimized by adjusting the timing of messages used for broadcast messages sent by routing or other protocols. Broadcast messages, such as network routing topology messages, may be controlled in two phases. In a first phase, the broadcast messages are sent with at a high rate to allow nodes to join the network rapidly. In a second phase, the broadcast messages are sent with at a lower rate to minimize interference with data and other messages in the network.

摘要： Systems and Methods for task allocation in a multiprocessor environment employing power management techniques are described wherein tasks are allocated relative to the density given by the ratio of worst-case-execution time and deadline of a task and also the harmonicity of a task's period with respect to a task-set. Tasks are allocated to a given processor based on either minimum density or maximum harmonicity depending on which allocation results in a lower clock frequency. Assigning a task to the processor with lowest density results in balancing the density across processors while assigning task to the processor with maximum harmonicity attempts to maximize the utilization of the processor.

摘要： Dynamically reducing power consumption by a processor in a computer system by determining a maximum number of times (token count) that the processor can incur a start-up delay after being placed into a low-power mode during a token period of time when executing a task for a token period of time. The processor may be placed into the low-power mode while executing the task in response to an idle indicator only if a current value of the token count assigned to the task is greater than zero. The current value of the token count is decremented each time the processor incurs a start-up delay in response to being awakened from the low-power mode. The current token count is reset to match the assigned token count at the end of each token period. Furthermore, wakeup may be anticipated to allow the processor to be awakened preemptively.

摘要： A method for interference management in a self optimizing network includes determining quality of service constraints for a call; mapping the quality of service constraints for the call to a target signal-to-interference noise ratio; and transmitting power control signals for the call based on the target signal-to-interference noise ratio. The utility function can be optimized for each class of calls over the network so as to maximize the total number of calls that can be handled.
