Abstract
According to various embodiments of the invention a device can announce broadcast traffic in a global access period. Thus, a destination can change its local communication window every global access period. By announcing a local communication window during a global access period it can be more likely that a source device in a network will receive the information because all devices should be active during the global access period. A device can awaken for its local communication window and during the local communication window a source device can schedule a transmission and transmit information to the device.

A method of power management, comprising:
- transmitting the time of a local communication window to other devices in a network;
- waking from a hibernation state at a predetermined time for the local communication window;
- receiving a transmission from another device in the network during the local communication window;
- and
- returning to the hibernation state after the local communication window.
A network device comprising:
- a memory, the memory configured to store instructions;
- a processor coupled to the memory and configured to execute the instructions to perform the following steps:
- transmitting the time of a local communication window to other devices in a network;
- waking from a hibernation state at a predetermined time for the local communication window;
- receiving a transmission from another device in the network during the local communication window;
- and
- returning to the hibernation state after the local communication window.
