Abstract

Methods, apparatus, systems and articles of manufacture are disclosed to coordinate node level adaptations. An example apparatus includes an adaptation support determiner to determine if an adaptation in an adaptation message is supported by a first device, an extractor to, in response to the determination that the adaptation in the adaptation message is supported by the first device, calculate a start-time for the first device based on (a) a transit duration of the adaptation message, (b) an execution duration of the adaptation in the adaptation message, and (c) a timestamp of when the second device sent the adaptation message, and an initiate a timer value for the first device and the second device, the timer value being a function of the start-time. The example apparatus further includes an installer to, in response to the timer value satisfying a threshold, execute the adaptation to reduce disruptions in the CPS.

First claim

What is claimed is:

1. An apparatus to reduce disruptions in a cyber physical system (CPS), the apparatus comprising:
an adaptation support determiner to determine if an adaptation in an adaptation message is supported by a first device, the adaptation message being sent by a second device;
an extractor to, in response to the determination that the adaptation in the adaptation message is supported by the first device:
calculate a start-time for the first device based on (a) a transit duration of the adaptation message, (b) an execution duration of the adaptation in the adaptation message, and (c) a timestamp of when the second device sent the adaptation message; and
initiate a timer value for the first device and the second device, the timer value being a function of the start-time;

an installer to, in response to the timer value satisfying a threshold, execute the adaptation to reduce disruptions in the CPS; and
a success determiner to, in response to determining the adaptation improves an operating parameter by at least an adaptation benefit threshold, notify other devices to execute the adaptation, the adaptation support determiner, the extractor, the installer, and the success determiner implemented by a processor.

2. The apparatus of claim 1 , wherein the extractor is to send the timer value to the second device to coordinate execution of the adaptation between the first device and the second device.

3. The apparatus of claim 1 , wherein the threshold is satisfied when the timer value expires.

4. The apparatus of claim 1 , further including a system model updater to update a first model to include data representing at least one of energy usage, resource usage, or execution time.

5. The apparatus of claim 1 , wherein the adaptation support determiner is to notify the other devices to not execute the adaptation until the success determiner has determined the adaptation improves the operating parameter.

6. The apparatus of claim 1 , wherein the operating parameter includes at least one of energy usage, resource usage, or execution time.

7. An apparatus for reducing disruptions in a cyber physical system (CPS), the apparatus comprising:
means for determining if an adaptation in an adaptation message is supported by a first device, the adaptation message being sent by a second device;
in response to the determination that the adaptation in the adaptation message is supported by the first device, means for controlling a timer, the timer controlling means to:
calculate a start-time for the first device based on (a) a transit duration of the adaptation message, (b) an execution duration of the adaptation in the adaptation message, and (c) a timestamp of when the second device sent the adaptation message; and
initiate a timer value for the first device and the second device, the timer value being a function of the start-time;

in response to the timer value satisfying a threshold, means for installing, the installing means to execute the adaptation to reduce disruptions in the CPS; and
in response to determining the adaptation improves an operating parameter by at least an adaptation benefit threshold, means for notifying to cause other devices to execute the adaptation, the determining means, the timer controlling means, the installing means, and the notifying means implemented by at least one processor.

8. The apparatus of claim 7 , wherein the timer controlling means is to send the timer value to the second device to coordinate execution of the adaptation between the first device and the second device.

9. The apparatus of claim 7 , wherein the threshold is satisfied when the timer value expires.

10. The apparatus of claim 7 , further including means for model updating to update a first model to include data representing at least one of energy usage, resource usage, or execution time.

11. The apparatus of claim 7 , further including means for notifying to prevent execution of the adaptation on the other devices until the adaptation is determined to improve the operating parameter.

12. The apparatus of claim 7 , wherein the operating parameter includes at least one of energy usage, resource usage, or execution time.

13. A non-transitory computer readable medium comprising computer readable instructions which, when executed, cause at least one processor to at least:
determine if an adaptation in an adaptation message is supported by a first device, the adaptation message being sent by a second device;
in response to the determination that the adaptation in the adaptation message is supported by the first device, calculate a start-time for the first device based on (a) a transit duration of the adaptation message, (b) an execution duration of the adaptation in the adaptation message, and (c) a timestamp of when the second device sent the adaptation message, and initiate a timer value for the first device and the second device, the timer value being a function of the start-time;
in response to the timer value satisfying a threshold, execute the adaptation to reduce disruptions in a cyber physical system (CPS); and
in response to determining the adaptation improves an operating parameter by at least an adaptation benefit threshold, notify other devices to execute the adaptation.

14. The computer readable medium of claim 13 , wherein the instructions, when executed, cause the at least one processor to send the timer value to the second device to coordinate execution of the adaptation between the first device and the second device.

15. The computer readable medium of claim 13 , wherein the threshold is satisfied when the timer value expires.

16. The computer readable medium of claim 13 , wherein the instructions, when executed, cause the at least one processor to update a first model to include data representing at least one of energy usage, resource usage, or execution time.

17. The computer readable medium of claim 13 , wherein the instructions, when executed, cause the at least one processor to notify the other devices to not execute the adaptation until the adaptation improves the operating parameter.

18. The computer readable medium of claim 13 , wherein the operating parameter includes at least one of energy usage, resource usage, or execution time.

19. A computer implemented method to reduce disruptions in a cyber physical system (CPS), the method comprising:
determining, by executing an instruction with at least one processor, if an adaptation in an adaptation message is supported by a first device, the adaptation message being sent by a second device;
in response to the determination that the adaptation in the adaptation message is supported by the first device, calculating, by executing an instruction with at least one processor, a start-time for the first device based on (a) a transit duration of the adaptation message, (b) an execution duration of the adaptation in the adaptation message, and (c) a timestamp of when the second device sent the adaptation message, and initiating, by executing an instruction with at least one processor, a timer value for the first device and the second device, the timer value being a function of the start-time;
in response to the timer value satisfying a threshold, executing, by executing an instruction with at least one processor, the adaptation to reduce disruptions in the CPS; and
in response to determining the adaptation improves an operating parameter by at least an adaptation benefit threshold, notifying other devices to execute the adaptation.
