Abstract

Systems, master node-based apparatus, and methods are described for enhanced monitoring for an event candidate within a wireless node network. Such a system may include a low-level ID node and a mid-level master node. The master node receives a first group of signals, and then detects if the ID node is broadcasting with a cycling broadcast RF power profile setting, receives a second plurality of advertising signals from the ID node also broadcast with this setting. The master node then determines a first average of an observed parameter for the first advertising signals within a first window of time commensurate with the cycling period and a second average of the observed parameter for the second advertising signals within a second window of time commensurate with the cycling period. The master node then identifies and reports the event candidate when a comparison of the first average and the second average indicates a threshold observed change relative to the ID node.

First claim

What is claimed is:

1 . An enhanced monitoring system for identifying an event candidate within a wireless node network having a server, the system comprising:
at least one ID node disposed at a low level within the wireless node network, the ID node being incapable of communicating directly with the server; a master node disposed at a middle level within the wireless node network as a monitoring intermediary between the ID node and the server, wherein the master node further comprises
a master node processing unit,
a memory storage coupled to the master node processing unit, the memory storage maintaining event detection engine code for execution by the master node processing unit,
a first communication interface coupled to the node processing unit and operative to communicate directly the ID node over a first communication path;
a second communication interface coupled to the node processing unit and operative to communicate directly with the server over a second communication path, wherein the first communication path is distinct from the second communication path;
wherein as the ID node broadcasts a first plurality of signals over the first communication path, the master node, when executing the event detection engine code on the master node processing unit, is operative to
receive the first plurality of advertising signals using the first communication interface,
detect if the ID node is broadcasting with a cycling broadcast RF power profile setting based upon at least one of the first plurality of advertising signals, the cycling broadcast RF power profile setting defining a cycle period over which the ID node alters how it broadcasts at different RF power levels,
detect an observed parameter for each of the first plurality of advertising signals, and
determine a first average of the observed parameters for the first plurality of advertising signals within a first window of time commensurate with the cycle period; and
wherein as the ID node broadcasts a second plurality of signals over the first communication path, the master node, when continuing to execute the event detection engine code on the master node processing unit, is operative to
receive the second plurality of advertising signals broadcast by the ID node after the ID node broadcasts the first plurality of advertising signals, wherein the second plurality of advertising signals are broadcast with the cycling broadcast RF power profile setting,
detect an observed parameter for each of the second plurality of advertising signals,
determine a second average of the observed parameters for the second plurality of advertising signals within a second window of time commensurate with the cycle period,
identify the event candidate relative to the ID node when a comparison of the first average and the second average indicates an observed change relative to the ID node, and
cause the second communication interface to send a reporting message to the server, the reporting message indicating the identified event candidate relative to the ID node.

2 . The system of claim 1 , wherein the cycling broadcast RF power profile setting periodically has the first ID node how it broadcasts at the different RF power levels.

3 . The system of claim 1 , wherein the cycle period comprises a first period where the first ID node broadcasts at a low-power level, a second period where the first ID node broadcasts at a mid-power level, and a third period where the first ID node broadcasts at a high-power level.

4 . The system of claim 1 , wherein the detecting step further comprises parsing, by the master node, the at least one of the first plurality of advertising signals to identify a part of a signal header defining the cycling broadcast RF power profile setting.

5 . The system of claim 4 , wherein the cycling broadcast RF power profile setting indicates that the first ID node is currently operating in a mode that periodically has the first ID node changing the RF power level broadcast in each of the first plurality of advertising signals.

6 . The system of claim 1 , wherein the observed change comprises a threshold difference between the first average and the second average.

7 . The system of claim 1 , wherein the observed parameter comprises a signal strength value as detected by the master node; and wherein the observed change comprises a threshold power difference between the first average and the second average.

8 . The system of claim 1 , wherein the event candidate reported to the server over the second communication interface avoids the need for the master node to update the server with information about the signal strength value of each of the first plurality of signals and the second plurality of signals broadcast from the first ID node.

9 . An enhanced master node apparatus for identifying an event candidate within a wireless node network having at least one ID node and a server, the ID node being disposed a low level within the wireless node network and being incapable of communicating directly with the server while the master node apparatus is disposed at a middle level within the wireless node network as a monitoring intermediary between the ID node and the server, the master node apparatus comprising:
a node processing unit, a memory storage coupled to the master node processing unit, the memory storage maintaining event detection engine code for execution by the master node processing unit, a first communication interface coupled to the node processing unit and operative to communicate directly the ID node over a first communication path; a second communication interface coupled to the node processing unit and operative to communicate directly with the server over a second communication path, wherein the first communication path is distinct from the second communication path; wherein the master node, when executing the event detection engine code on the master node processing unit, is operative to
receive a first plurality of advertising signals broadcast by the ID node using the first communication interface,
detect if the ID node is broadcasting with a cycling broadcast RF power profile setting based upon at least one of the first plurality of advertising signals, the cycling broadcast RF power profile setting defining a cycle period over which the ID node alters how it broadcasts at different RF power levels,
detect an observed parameter for each of the first plurality of advertising signals,
determine a first average of the observed parameters for the first plurality of advertising signals within a first window of time commensurate with the cycle period,
receive a second plurality of advertising signals broadcast by the ID node after the ID node broadcasts the first plurality of advertising signals, wherein the second plurality of advertising signals are broadcast with the cycling broadcast RF power profile setting,
detect an observed parameter for each of the second plurality of advertising signals,
determine a second average of the observed parameters for the second plurality of advertising signals within a second window of time commensurate with the cycle period,
identify the event candidate relative to the ID node when a comparison of the first average and the second average indicates an observed change relative to the ID node, and
cause the second communication interface to send a reporting message to the server, the reporting message indicating the identified event candidate relative to the ID node.

10 . The master node apparatus of claim 9 , wherein the cycling broadcast RF power profile setting periodically has the first ID node how it broadcasts at the different RF power levels.
