Method of communicating in wireless network

A method of performing handover at a coordinator in a wireless network in which a high rate physical channel and a low rate physical channel are used for communication, the wireless network including at least one device, the method comprising:

• receiving information associated with a priority of a device from the device when the device joins the wireless network;
• transmitting a handover request message to the device if the priority of the device is higher than a priority of the coordinator;
• receiving a response to the handover request message from the device;
• and
• broadcasting a first beacon on the low rate physical channel, the first beacon including information which indicates that the device will be a new coordinator of the wireless network.

A coordinator used in a wireless network in which a high rate physical channel and a low rate physical channel are used for communication, the wireless network including at least one device, wherein the coordinator is configured to:

• receive information associated with a priority of a device from the device when the device joins the wireless network;
• transmit a handover request message to the device if the priority of the device is higher than a priority of the coordinator;
• receive a response to the handover request message from the device;
