1. A sensor interoperability system, comprising:
- one or more sensors that each generate a piece of sensor data;
one or more sensor proxies, each sensor proxy coupled to one of the one or more sensors wherein each sensor proxy processes the piece of sensor data from the sensor to create a sensor system piece of data wherein the sensor system piece of data has a common format, wherein each sensor proxy sets parameters for the sensor associated with the sensor proxy using a set command, retrieves data from the sensor associated with the sensor proxy using a get command and publishes the sensor system piece of data using a publish command; and
a policy unit coupled to the one or more sensor proxies over a communications path, wherein the policy unit further comprises one or more policies wherein each policy further comprises a condition and an action wherein the condition tests a sensor system piece of data and the action is an action that occurs when the condition is satisfied and a policy engine that applies the one or more policies to the sensor system piece of data.

Abstract
A novel method and software system design are presented for interchanging sensors from different vendors in a plug and play manner to drive mission critical applications within a sensor based architecture, policy based framework, event-based architecture. This technique is applicable to sensors directly attached to a computer, or sensors attached to a network, or sensors attached to a controller node which is attached to a network or directly attached to a computer.

11. A method for monitoring a system using a sensor network, comprising:
-
generating a piece of sensor data at each of one or more sensors; processing, using a processor-based sensor proxy, each piece of sensor data of each sensor to create a sensor system piece of data wherein the sensor system piece of data has a common format, wherein each sensor proxy sets parameters for the sensor associated with the sensor proxy using a set command, retrieves data from the sensor associated with the sensor proxy using a get command and publishes the sensor system piece of data using a publish command; determining, using a processor-based policy engine, if the sensor piece of data triggers a policy contained in the policy engine wherein the policy is triggered when the sensor system piece of data meets a condition of one or more policies stored in the policy engine; and performing, using the processor-based policy engine, an action of the triggered policy. - View Dependent Claims (12, 13, 14, 15, 16)
