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.
