MESH INFRASTRUCTURE UTILIZING ALTERNATIVE COMMUNICATION PATHS
First Claim
1. A wireless network comprising:
- a control node; and
a plurality of communication nodes in wireless communication with the control node, each of the communication nodes having a wireless communication path to the control node that is either a direct path or an indirect path through one or more other communication nodes that serve as repeaters,wherein, for each communication node in wireless communication with the control node, the control node determines an alternative communication path and stores primary communication path information and alternative communication path information.

Abstract
A wireless mesh network, method, and processor-readable storage medium for maintaining both a primary communication path and an alternative communication path for a communication node are disclosed herein. A control node determines an alternative communication path for each node in communication with the control node and stores, for each node, primary communication path information and alternative communication path information. By maintaining both primary and alternative communication path information, the control node can switch from the primary path to the alternative path when a failure in the primary path is detected. Because the control node determines and stores information relating to the alternative path before the failure occurs, switching from the primary path to the alternative path involves little, if any, delay.

8. In a network having a control node that communicates with a plurality of communication nodes, wherein each of the communication nodes has a wireless communication path to the control node that is either a direct path or an indirect path through one or more other communication nodes that serve as repeaters, a method of operating the network, the method comprising:
-
causing the control node to instruct the communication nodes in wireless communication with the control node to respond to node scans; causing the control node to instruct a first communication node in wireless communication with the control node to conduct a node scan to identify a plurality of second communication nodes within communication range of the first communication node; and causing the control node to determine an alternative communication path from the control node to the first communication node and to store primary communication path information and alternative communication path information associated with the first communication node. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A processor-readable storage medium storing processor-executable instructions that, when executed by a processor, cause the processor to operate a wireless mesh network having a control node that communicates with a plurality of communication nodes, wherein each of the communication nodes has a wireless communication path to the control node that is either a direct path or an indirect path through one or more other communication nodes that serve as repeaters, the processor-executable instructions comprising instructions for causing the control node to:
-
instruct the communication nodes in wireless communication with the control node to respond to node scans; instruct a first communication node in wireless communication with the control node to conduct a node scan to identify a plurality of second communication nodes within communication range of the first communication node; and determine an alternative communication path from the control node to the first communication node and to store primary communication path information and alternative communication path information associated with the first communication node. - View Dependent Claims (16, 17, 18, 19, 20)
