Abstract

A networked system for managing a physical intrusion detection/alarm includes an upper tier of server devices, comprising: processor devices and memory in communication with the processor devices, a middle tier of gateway devices that are in communication with upper tier servers, and a lower level tier of devices that comprise fully functional nodes with at least some of the functional nodes including an application layer that execute routines to provide node functions, and a device to manage the lower tier of devices, the device instantiating a program manager that executes a state machine to control the application layer in each of the at least some of the functional nodes.

Claims

1. A networked sensor system comprises:

an upper tier of server devices, the server devices comprising;

processor devices; and

memory in communication with the processor devices;

a middle tier of gateway devices that are in communication with one or more of the upper tier server devices;

a lower level tier of devices that comprise fully functional sensor nodes with at least some of the fully functional sensor nodes including an application layer that executes routines to provide node sensor functions and an application layer manager to manage the application layer in the at least some of the functional nodes in the lower tier of devices, with the application layer manager, configured to;

manage changes in functions in respective ones of the at least some of the functional nodes in the lower tier;

characterize inputs to the respective ones of the at least some of the functional nodes; and

apply rules to determine changes in one or more of configuration, stored data and message generation by the respective ones of the at least some of the functional nodes.

2. The networked system of claim 1, wherein the lower tier fully-functional nodes are wireless devices and constrained wireless nodes or end-nodes that are sensors for a physical intrusion detection/alarm monitoring system.

3. The networked system of claim 1, wherein the gateway devices are equipped with an access point where a function node is physically attached to that access point, and provides a wireless connection point to other nodes in the wireless network.

4. The networked system of claim 1, wherein the application layer manager includes a state machine comprised of sets of functions that execute in coordination, where functions are individually deleted, substituted, or added in order to alter states in the state machine.

5. The networked system of claim 1, wherein the application layer manager uses an edge device operating system that allows for loading and execution of individual functions after the booting of the device or without rebooting the device.

6. The networked system of claim 1, wherein the application layer manager receives requests from state functions and in response handles pass-offs of functions currently operating to destination functions.

7. The networked system of claim 6, wherein the application layer manager accesses a transition table that stores a central descriptor for the state functions.

8. The networked system of claim 1, wherein the application layer manager is firmware and is isolated from other firmware modules in the lower tier devices.

9. A method of managing a networked sensor system, the method comprising:

operating the networked system arranged into an upper tier of server devices, a middle tier of gateway devices that are in communication with upper tier servers and a lower level tier of sensor devices that are fully functional nodes with at least some of the functional nodes including an application layer that execute routines to provide sensor node functions; and

managing the lower tier of devices through device executed application layer managers that execute state machines to control application layers in each of the at least some of the functional nodes, with the application layer managers, managing changes in functions in respective ones of the at least some of the functional nodes in the lower tier of devices by;

characterizing inputs to the respective ones of the at least some of the functional nodes; and

applying rules to determine changes in one or more of configuration, stored data and message generation by the respective ones of the at least some of the functional nodes.

10. The method of claim 9, wherein the lower tier fully-functional nodes are wireless devices and constrained wireless nodes or end-nodes that are sensors for a for physical intrusion detection/alarm monitoring system.

11. The method of claim 9, wherein the state machine is comprised of sets of functions that execute in coordination, where functions are individually deleted, substituted, or added in order to alter states in the state machine.
