Abstract
A power line communication (PLC) network and method, in which a coordinator can be changed. The PLC network includes a coordinator and a standby coordinator. The coordinator performs scheduling coordination in a PLC cell and periodically transmits scheduling information about the scheduling coordination to stations in the PLC cell. The standby coordinator serves as the new coordinator instead of the coordinator when the coordinator does not operate for a predetermined amount of time.
