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.

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.
