Dynamic functionality partitioning
A sensor and processing system dynamically partitions functionality between various remote sensor nodes and a processing subsystem based on available communication capabilities. Redundant functionality is located at the processing subsystem and each of the various remote sensor nodes, and each sensor node coordinates with the processing subsystem to determine the location (e.g., at the processing subsystem or at the sensor node) at which a particular functionality is executed.
1. A method comprising:
detecting communication capabilities of a communications channel between a sensor node and a processing subsystem, the communications channel carrying a sensor data stream from the sensor node to the processing subsystem, the sensor node being located at a different location than the processing subsystem; and
adjusting allocation of functionality between the sensor node and the processing subsystem based on the detected communication capabilities, wherein the adjusting the allocation of functionality causes one of the sensor node or the processing subsystem to perform a process on sensor data and causes the other of the sensor node or the processing subsystem to not perform the process on the sensor data, thereby changing characteristics of the sensor data communicated in the sensor data stream.
2. The method of claim 1 wherein the characteristics of the sensor data communicated between the sensor node and the processing subsystem in the sensor data stream before the adjusting the allocation of functionality and the characteristics of data communicated between the sensor node and the processing subsystem in the sensor data stream after the adjusting the allocation of functionality differ by a communication bandwidth used to communicate the sensor data between the sensor node and the processing subsystem.
3. The method of claim 1 wherein the characteristics of the sensor data communicated between the sensor node and the processing subsystem in the sensor data stream before the adjusting the allocation of functionality and the characteristics of data communicated between the sensor node and the processing subsystem in the sensor data stream after the adjusting the allocation of functionality differ by a level of encryption applied to the sensor data communicated between the sensor node and the processing subsystem.
4. The method of claim 1 wherein the processing subsystem and the sensor node each include a preprocessor block that performs the same preprocessor functionality.
5. The method of claim 4 wherein at least one of the processing subsystem and the sensor node further includes a preprocessor block that provides preprocessor functionality that is not provided by the other of the processing subsystem or the sensor node.
6. The method of claim 1 wherein the adjusting the allocation of functionality comprises:
enabling one or more preprocessor blocks of at least one of the sensor node or the processing subsystem to accommodate a change in communication channel bandwidth.
7. The method of claim 1 wherein the adjusting the allocation of functionality comprises:
disabling one or more preprocessor blocks of at least one of the sensor node or the processing subsystem to accommodate a change in communication channel bandwidth.
8. The method of claim 1 wherein the adjusting the allocation of functionality comprises:
enabling a preprocessor block of one of the sensor node or the processing subsystem; and
disabling a corresponding preprocessor block in the other one of the sensor node or the processing subsystem.
9. A computer memory having encoded thereon computer-executable instructions that upon execution configure a computer to perform operations comprising:
detecting communication capabilities of a communications channel between a sensor node and a processing subsystem, the communications channel carrying a sensor data stream from the sensor located at a first location and the processing subsystem located at a second location; and
adjusting allocation of functionality provided by preprocessor blocks between the sensor node and the processing subsystem based on the detected communication capabilities, wherein the adjusting the allocation of functionality causes one of the sensor node or the processing subsystem to perform a process on sensor data and causes the other of the sensor node or the processing subsystem to not perform the process on the sensor data, thereby changing characteristics of the sensor data communicated in the sensor data stream.
10. The computer memory of claim 9 wherein the adjusting the allocation of functionality comprises:
enabling one or more preprocessor blocks of at least one of the sensor node or the processing subsystem to perform the function and to accommodate a change in communication channel bandwidth.
11. The computer memory of claim 9 wherein the adjusting the allocation of functionality comprises:
disabling one or more preprocessor blocks of at least one of the sensor node or the processing subsystem to accommodate a change in communication channel bandwidth.
12. The computer memory of claim 9 wherein the adjusting the allocation of functionality comprises:
enabling a preprocessor block of one of the sensor node or the processing subsystem; and
disabling a corresponding preprocessor block in the other one of the sensor node or the processing subsystem.
13. A system comprising:
one or more memories;
one or more processors coupled to the one or more memories;
one or more modules stored in the one or more memories and operable on the one or more processors, the one or more modules comprising:
a communications interface module configured to detect communication capabilities of a communications channel between a sensor node and a processing subsystem, the communications channel carrying a first sensor data stream; and
a partitioning controller module configured to adjust allocation of functionality between the sensor node and the processing subsystem based on the detected communication capabilities, wherein the adjusting the allocation of functionality causes one of the sensor node or the processing subsystem to perform a process on sensor data and causes the other of the sensor node or the processing subsystem to not perform the process on the sensor data, thereby changing characteristics of the sensor data communicated in the sensor data stream.
14. The system of claim 13 wherein the characteristics of the data in the sensor data stream before the adjusting the allocation of functionality and the characteristics of the sensor data in the sensor data stream after the adjusting the allocation of functionality differ by an amount of preprocessing performed on the sensor data by the sensor node or the processing subsystem.
15. The system of claim 13 wherein the processing subsystem and the sensor node each include one or more preprocessor blocks that are capable of performing overlapping preprocessor functionality.
16. The system of claim 13 wherein the processing subsystem and the sensor node each include a preprocessor block that performs the same preprocessor functionality.
17. The system of claim 16 wherein at least one of the processing subsystem and the sensor node further includes a preprocessor block that provides preprocessor functionality that is not provided by the other of the processing subsystem or the sensor node.
