Power management mode aware mesh beacon collision avoidance and information update mechanism
First Claim
1. A method, comprising:
- at a first mesh point in a wireless mesh network, detecting that a beacon transmission parameter of the first mesh point has changed;
generating a message containing updated beacon transmission parameter information;
determining when a second mesh point operating in a power saving mode will transition to an awake state; and
transmitting the message containing the updated beacon transmission information during a time corresponding to the awake state of the second mesh point.

Abstract
Apparatus, methods and computer program products provide power management mode aware mesh beacon collision avoidance and information update mechanisms at a first mesh point in a wireless mesh network. The information update mechanism operates by detecting that a timing-related beacon transmission parameter of the first mesh point has changed; generating a message containing updated timing-related beacon transmission parameter information for the first mesh point; determining when a second mesh point operating in a power saving mode will transition to an awake state; and transmitting the message containing the updated timing-related beacon transmission information during a time corresponding to the awake state of the second mesh point.
