1. A method, comprising:
- receiving, by a sensor data control system, a request to change a configuration of a wireless node in a wireless sensor network at a monitored location, the wireless node supporting one or more sensors at the monitored location;
transmitting, by the sensor data control system, a configuration message for delivery to the wireless node, the configuration message including configuration information that enables the wireless node to change at least one configuration setting used by the wireless node in controlling a delivery of sensor data from the one or more sensors to the sensor data control system;
generating, by the sensor data control system, a first configuration hash value using a hash function having an input based on the at least one configuration setting identified by the request;
receiving, by the sensor data control system from a gateway device at the monitored location, a status message associated with the wireless node at the monitored location, the status message including a second configuration hash value generated by the wireless node using the hash function and having an input based on current configuration settings of the wireless node;
comparing, by the sensor data control system, the first configuration hash value to the second configuration hash value; and
when the comparison indicates that the first configuration hash value is different from the second configuration hash value, retransmitting, by the sensor data control system to the gateway device, the configuration message based on the request to effect a change in the current configuration settings of the wireless node.

8. A method, comprising:
-
transmitting, by a sensor data control system, a configuration message for delivery to a wireless node at a monitored location, the configuration message including configuration information that enables the wireless node to change at least one configuration setting used by the wireless node in controlling a delivery of sensor data from one or more sensors to the sensor data control system; receiving, by the sensor data control system from a gateway device at the monitored location, a status message associated with the wireless node at the monitored location, the status message including a first configuration hash value generated by the wireless node using a hash function and having an input based on current configuration settings of the wireless node; comparing, by the sensor data control system, the first configuration hash value to a second configuration hash value, wherein the second configuration hash value is produced by the sensor data control system using the hash function and having an input based on a stored set of configuration settings for the wireless node; and when the comparison indicates that the first configuration hash value is different from the second configuration hash value, retransmitting, by the sensor data control system to the gateway device, the configuration message based on the stored set of configuration settings to effect a change in the current configuration settings of the wireless node. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having a configuration update tool stored thereon for use by one or more server devices, the configuration tool including:
-
a transmission section that when executed, causes the configuration update tool to transmit a configuration message for delivery to a wireless node at a monitored location, the configuration message including configuration information that enables the wireless node to change at least one configuration setting used by the wireless node in controlling a delivery of sensor data from one or more sensors to a sensor data control system; a comparison section that when executed, causes the configuration update tool to compare a first configuration hash value to a second configuration hash value, the first configuration hash value generated by the wireless node at the monitored location using a hash function and having an input based on current configuration settings of the wireless node, the second configuration hash value retrieved from a memory storage device using an identifier associated with the wireless node, wherein the second configuration hash value is produced by the configuration update tool using the hash function and having input values based on a stored set of configuration settings for the wireless node; and an update section that when executed, causes the configuration update tool to initiate a configuration update retransmission to the gateway device when the comparison indicates that the first configuration hash value is different from the second configuration hash value, wherein the configuration update retransmission includes the configuration message based on the stored set of configuration settings to effect a change in the current configuration settings of the wireless node. - View Dependent Claims (16, 17, 18, 19, 20)
