Wireless mesh network controller synchronization
First Claim
Patent Images
1. A method of synchronizing a controller with an existing wireless mesh network, comprising:
- sending a network synchronization signal from the controller indicating that sleep timing information is lost; and
receiving a reply from one or more wireless mesh network nodes within the existing wireless mesh network comprising sleep timing information for the wireless mesh network;
wherein the network synchronization signal comprises a sync pulse repeated at a higher than normal rate, wherein the higher than normal rate is such that the network synchronization signal is sent at least twice during a minimum wake period of the wireless mesh network nodes.

Abstract
A set sleep period is coordinated among a plurality of mesh network nodes to conserve power. A controller is synchronized with an existing wireless mesh network by sending a network synchronization signal from the controller indicating that sleep timing information is lost, and receiving a reply from one or more wireless mesh network nodes within the existing wireless mesh network comprising sleep timing information for the wireless mesh network.
