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 and constrained nodes. The networked has a device configured to receive sensory inputs from credentials or badges and determine virtual groups of individuals associated with received credential data and apply rules to grouping information to track and detect individuals within virtual groups.

Claims

1. A networked system for physical intrusion detection/alarm monitoring comprises:

one or more computing devices, comprising processor devices and memory in communication with the processor devices, configured to

receive sensory inputs from credentials or badges within a monitored premises;

determine virtual groups of individuals associated with the received credential data by determining from the received inputs relative proximity of individuals to each other over periods of time;

store the determined virtual groups of individuals into a list of tag locations;

modify over time frames of configurable duration the virtual groupings by changing the list of tag locations for each virtual group as virtual group membership changes, and

apply rules set to the grouping information to track and detect individuals within the virtual group.

2. The networked system of claim 1 wherein locations of individuals are determined by triangulation of credential data from plural credential reading devices and/or TX power level sweeping.

3. The networked system of claim 1 wherein messages are passed between name badge nodes and other sensor network nodes in a premises that is monitored.

4. The networked system of claim 1 wherein after a period of time an application running in the network gateway computes the location of each of the individuals and a group identifier application scans a list of tag locations.

5. The networked system of claim 1 wherein the groupings are dynamic in that they form, dissolve, and otherwise change in real-time as new information is made available regarding the current location of the individuals.

6. The networked system of claim 1 wherein the groupings are “

fuzzy”

in that a given individual may be assigned to a group with a certain degree of certainty/uncertainty derived from past experience.

7. The networked system of claim 1 wherein the one or more computing devices are further configured to:

apply rules to define a test for virtual group membership.

8. The networked system of claim 1 wherein the one or more computing devices is a single device in the networked system.

9. The networked system of claim 1 wherein the one or more computing devices is a plurality of distributed devices of a set of end-nodes and combinations of network nodes and hosts.

10. The networked system of claim 1 wherein the context specific rules or sets of rules are application code modules loaded into the devices and that change over time, using real-time code relocation and execution.

11. A method of detection of physical intrusion within a monitored area, the method comprising:

receiving by one or more computing devices, sensory inputs from credentials or badges within a monitored premises;

determining by the one or more computing devices, virtual groups of individuals associated with the received credential data by determining from the received inputs relative proximity of individuals to each other over periods of time;

storing by the one or more computing devices, the determined virtual groups of individuals into a list of tag locations;

modify by the one or more computing devices over time frames of configurable duration the virtual groupings by changing the list of tag locations for each virtual group as virtual group membership changes; and

applying by the one or more computing devices, rules set to the grouping information to track and detect individuals within the virtual group.

12. The method of claim 11 further comprising:

receiving by the one or more computing devices, modifications of the rules; and

updating sensors on the network according to the modifications made to the rules.
