Abstract

Aspects relate to automatic execution of a target action, which can be energy-intensive tasks, processing compute-intensive tasks, interaction with a node, or combinations thereof. A context aware trigger, power aware trigger, a randomly scheduled wakeup trigger, a deterministically scheduled wakeup trigger, and/or a predictively scheduled wakeup trigger can be utilized to determine the availability of contexts associated with the target action. Based on the availability of a context that should be available, one or more target actions are automatically executed and/or selectively suspended.

Claims

1. A method for automatically triggering execution of a target action, comprising:

determining a desired context as a function of the target action, wherein the desired context comprises a connection to a power supply external to a wireless communications apparatus;

evaluating availability of the desired context based on a predictive schedule that is a function of historical information, wherein evaluating availability of the desired context comprises evaluating whether the wireless communications apparatus is connected to an external power supply based on the predictive schedule that is a function of historical information about when the wireless communications apparatus previously connected to an external power supply, and wherein the predictive schedule comprises an estimated future time for evaluating the availability and an interval and a time window for re-evaluating the availability when the desired context is not available at the estimated future time; and

executing the target action automatically if the desired context is available.

2. The method of claim 1, further comprising retaining data associated with the target action if the context is not available.

3. The method of claim 1, further comprising:

monitoring the availability of the desired context;

suspending execution of the target action if the desired context is no longer available; and

retaining data associated with the suspended target action.

4. The method of claim 2, further comprising:

monitoring the availability of the desired context associated with the retained data; and

executing the target action with the retained data when the desired context is available.

5. The method of claim 1, wherein the desired context further comprises an availability of connectivity with a remote server.

6. The method of claim 1, wherein the target action is a distributed processing task over a wireless communication link.

7. The method of claim 1, wherein the desired context further comprises a processing performance level, and wherein the processing performance level includes a processing performance constraint.

8. The method of claim 7, wherein the processing performance constraint is less than or equal to an available performance measure, the available performance measure can be selectively modified based on performance requirements for associated tasks.

9. The method of claim 1, wherein the desired context further comprises a performance measure on a wireless link, and wherein the performance measure on the wireless link comprises a wireless link delay constraint, a wireless link bandwidth constraint, a wireless link power constraint, a wireless link interference constraint, an average wireless link throughput constraint, or combinations thereof.

10. The method of claim 1, wherein the desired context further comprises a performance measure on a wireless link, and wherein the performance measure on the wireless link is an end-to-end quality of service measure.

11. The method of claim 10, wherein the end-to-end quality of service measure comprises an end-to-end delay constraint, an end-to-end throughput constraint, or combinations thereof.

12. The method of claim 1, wherein the predictive schedule comprises a variable delay between two consecutive wakeup events.

13. The method of claim 12, wherein the delay between two consecutive wakeup events is increased to conserve power.

14. The method of claim 12, wherein the delay between two consecutive wakeup events is varied based on a likelihood of an occurrence of the desired context.

15. A wireless communications apparatus, comprising:

a memory that retains instructions related to;

determining a desired context as a function of a target action, wherein the desired context comprises a connection to a power supply external to the wireless communications apparatus,

evaluating availability of the desired context based on a predictive schedule that is a function of historical information, wherein evaluating availability of the desired context comprises evaluating whether the wireless communications apparatus is connected to an external power supply based on the predictive schedule that is a function of historical information about when the wireless communications apparatus previously connected to an external power supply, and wherein the predictive schedule comprises an estimated future time for evaluating the availability and an interval and a time window for re-evaluating the availability when the desired context is not available at the estimated future time, and

executing the target action automatically if the desired context is available; and

a processor, coupled to the memory, configured to execute the instructions retained in the memory.

16. The wireless communications apparatus of claim 15, wherein the memory further retains instructions related to storing data associated with the target action if the context is not available.

17. The wireless communications apparatus of claim 15, wherein the memory further retains instructions related to monitoring the availability of the desired context, suspending execution of the target action if the desired context is no longer available, and retaining data associated with the suspended target action.

18. The wireless communications apparatus of claim 17, wherein the memory further retains instructions related to monitoring the availability of the desired context associated with the retained data and executing the target action with the retained data when the desired context is available.

19. A wireless communications apparatus that automatically triggers execution of a target action, comprising:
