ABSTRACT:
A method (500) is provided for operating a network coordinator (110). The method includes receiving device capability information from a plurality of network devices (121-125), including whether each of the network devices can perform network control functions (520); determining whether any of the network devices is capable of performing network control functions based on the device capability information (540); choosing one of the network devices that is capable of performing network control functions to be a designated next coordinator if any of the network devices are capable of performing network control functions (570); determining that there will be no designated next coordinator if none of the network devices are capable of performing network control functions (550); and sending a beacon (220) to the network devices, the beacon including next coordinator information (300) indicating one of: the designated next coordinator, or that there is no designated next coordinator (580).
