Systems and methods for dynamically configuring node behavior in a sensor network
First Claim
1. A wireless sensor network, comprising:
- a first node configured to receive at least one script defining a new behavior for the network, the first node configured to wirelessly transmit the at least one script via the network; and
a sensor node configured to store event data and to receive the at least one script transmitted by the first node, the sensor node having a sensor for detecting an operational parameter of a device, wherein the sensor node via execution of the at least one script is configured to update the event data to indicate that the at least one script is to be invoked if the operational parameter exceeds a threshold, the sensor node further configured to compare the operational parameter to the threshold and to invoke the at least one script based on the event data when the threshold is exceeded by the operational parameter.

Abstract
The present disclosure generally pertains to systems and methods for controlling sensor networks. A sensor network has a plurality of sensor nodes, which have sensors for monitoring operational parameters of devices within an application-specific system. A wireless communication module is provided for each node to enable the node to wirelessly communicate with other nodes of the network. A user defines various scripts for controlling the behavior of one or more nodes, and the network distributes the scripts, as appropriate, to various nodes thereby implementing the behavior defined by the scripts. Accordingly, a user can easily and dynamically configure or re-configure the behavior of any node without having to physically access the node that is being configured or re-configured.

5. A method for dynamically changing node behavior for a wireless sensor network, comprising the steps of:
-
receiving at a first node at least one script defining a new behavior for the network; wirelessly transmitting the at least one script via the network to a sensor node; storing event data in the sensor node; detecting an operational parameter of a device via a sensor of the sensor node; updating the event data via execution of the at least one script by the sensor node such that the event data indicates that the at least one script is to be invoked if the operational parameter exceeds a threshold; comparing the operational parameter to the threshold; and invoking the at least one script based on the event data when the threshold is exceeded by the operational parameter. - View Dependent Claims (6)
