Finding missing wireless nodes
First Claim
1. A method for finding missing wireless nodes, comprising:
- creating a repeating schedule of communication between a data concentrator and one or more nodes wherein the data concentrator attempts to communicate with each of the one or more nodes at a discrete time slot for each node, wherein the schedule of communication further includes at least one dead time slot wherein the data concentrator does not attempt to communicate with any of the one or more nodes;
determining if each node has communicated with the data concentrator during a predetermined amount of discrete time slots;
identifying each node that does not communicate with the data concentrator during the predetermined amount of discrete time slot as a missing node;
attempting to communicate with each missing node during the at least one dead time slot; and
modifying the schedule to include dead time slots for each missing node, wherein if communications with a missing node has been reestablished, reestablishing the schedule to include the found node.

Abstract
A method for finding missing wireless nodes includes creating a repeating schedule of communication between a data concentrator and one or more nodes such that the data concentrator attempts to communicate with each of the one or more nodes at a discrete time slot for each node. The schedule of communication further includes at least one dead time slot such that the data concentrator does not attempt to communicate with any of the one or more nodes. The method also includes determining if each node has communicated with the data concentrator during a predetermined amount of discrete time slots, identifying each node that does not communicate with the data concentrator during the predetermined amount of discrete time slot as a missing node, and attempting to communicate with each missing node during the at least one dead time slot.

6. A non-transitory computer readable medium, comprising computer executable instructions that cause a processor to perform a method for finding missing wireless nodes, the method comprising:
-
creating a repeating schedule of communication between a data concentrator and one or more nodes wherein the data concentrator attempts to communicate with each of the one or more nodes at a discrete time slot for each node, wherein the schedule of communication further includes at least one dead time slot wherein the data concentrator does not attempt to communicate with any of the one or more nodes; determining if each node has communicated with the data concentrator during a predetermined amount of discrete time slots; identifying each node that does not communicate with the data concentrator during the predetermined amount of discrete time slot as a missing node; attempting to communicate with each missing node during the at least one dead time slot; and modifying the schedule to include dead time slots for each missing node, wherein if communications with a missing node has been reestablished, reestablishing the schedule to include the found node. - View Dependent Claims (7, 8, 9, 10)
