Abstract

A system for managing operation of a “whiteboard” supported by one or more devices. A whiteboard may comprise a shared storage area allocated amongst the memories of one or more devices enabled for wireless communication. The whiteboard may be accessed by various programs, or “nodes,” resident on the devices. In at least one scenario, some nodes may provide information to a whiteboard section of one device for use by nodes that may exist on other devices. This information may be accessible via wireless communication The present invention may evaluate the requirements of the various active nodes in view of the status of the plurality of devices in order to both optimize whiteboard operation while conserving device resources.

Claims

1. A method, comprising:

establishing a shared information space supported by one or more devices and accessible by at least one node residing on the one or more devices, wherein an available memory space is reserved for the at least one node within the shared information space;

determining if there are requirements for the at least one node;

if it is determined that there are requirements for the at least one node, updating the configuration of the shared information space based on the requirements; and

adjusting the operation of the one or more devices based on the updated configuration.

2. The method of claim 1, wherein the shared information space is a common information space for storing data that is divided between the memories of the one or more devices.

3. The method of claim 1, wherein an available memory space residing on a device is accessible to a node residing on another device via wireless communication.

4. The method of claim 1, wherein the at least one node may be of a type including at least proactive nodes, reactive nodes, or agent nodes that can be both proactive and reactive.

5. The method of claim 4, wherein determining if there are requirements for the at least one node includes determining whether any active nodes exist on the one or more devices, and whether the active nodes are of a proactive, reactive or agent type.

6. The method of claim 5, wherein determining if there are requirements for the at least one node includes determining whether any reactive nodes or agent nodes are consuming information being placed in an available memory space by an active proactive node.

7. The method of claim 5, wherein determining if there are requirements for the at least one node includes determining whether any reactive nodes or agent nodes on one device are consuming information being placed in an available memory space on another device.

8. The method of claim 1, further comprising determining device and connectivity characteristics for the one or more devices and adjusting the operation of the one or more devices based on both the updated configuration and the device and connectivity characteristics.

9. The method of claim 1, wherein adjusting the operations of the one or more devices includes changing the location of an available memory space.

10. The method of claim 1, wherein adjusting the operation of the one or more devices includes placing resources of the one or more devices in a power conservation mode.

11. A computer program product comprising a computer usable medium having computer readable program code embodied in said medium for propagating encryption key information, comprising:

a computer-readable program code configured to establish a shared information space supported by one or more devices and accessible by at least one node residing on the one or more devices, wherein an available memory space is reserved for the at least one node within the shared information space;

a computer-readable program code configured to determine if there are requirements for the at least one node;

if it is determined that there are requirements for the at least one node, a computer-readable program code configured to update the configuration of the shared information space based on the requirements; and

a computer-readable program code configured to adjust the operation of the one or more devices based on the updated configuration.

12. The computer program product of claim 11, wherein the shared information space is a common information space for storing data that is divided between the memories of the one or more devices.

13. The computer program product of claim 11, wherein an available memory space residing on a device is accessible to a node residing on another device via wireless communication.

14. The computer program product of claim 11, wherein the at least one node may be of a type including at least proactive nodes, reactive nodes, or agent nodes that can be both proactive and reactive.

15. The computer program product of claim 14, wherein determining if there are requirements for the at least one node includes determining whether any active nodes exist on the one or more devices, and whether the active nodes are of a proactive, reactive or agent type.

16. The computer program product of claim 15, wherein determining if there are requirements for the at least one node includes determining whether any reactive nodes or agent nodes are consuming information being placed in an available memory space by an active proactive node.

17. The computer program product of claim 15, wherein determining if there are requirements for the at least one node includes determining whether any reactive nodes or agent nodes on one device are consuming information being placed in an available memory space on another device.

18. The computer program product of claim 11, further comprising determining device and connectivity characteristics for the one or more devices and adjusting the operation of the one or more devices based on both the updated configuration and the device and connectivity characteristics.

19. A device, comprising:

one or more communication modules supporting at least one wireless communication medium;

at least one memory; and

at least one processor, the processor coupled to at least the one or more communication modules and the at least one memory, the processor being configured to;

participate in a shared information space supported by one or more devices and accessible by at least one node residing on the one or more devices, wherein an available memory space is reserved for the at least one node within the shared information space;

determine if there are requirements for the at least one node;

if it is determined that there are requirements for the at least one node, update the configuration of the shared information space based on the requirements; and

adjust the operation of the one or more devices based on the updated configuration.

20. The device of claim 19, wherein at least some of the at least one memory is persistent memory.

21. The device of claim 19, further comprising a connection controller for managing the operation of a whiteboard section resident in the at least one memory.

22. A device, comprising:

means for participating a shared information space supported by one or more devices and accessible by at least one node residing on the one or more devices, wherein an available memory space is reserved for the at least one node within the shared information space;

means for determining if there are requirements for the at least one node;

if it is determined that there are requirements for the at least one node, means for updating the configuration of the shared information space based on the requirements; and

means for adjusting the operation of the one or more devices based on the updated configuration.

23. The device of claim 22, wherein at least some of the at least one memory is persistent memory.

24. The device of claim 22, further comprising a connection controller for managing the operation of a whiteboard section resident in the at least one memory.

25. A system, comprising:

one or more devices configured for wireless communication;

the one or more devices participating in a shared information space accessible by at least one node residing on the one or more devices, wherein an available memory space is reserved for the at least one node within the shared information space;

at least one of the one or more devices determining if there are requirements for the at least one node;
