    摘要： A network relay apparatus and method are provided. The network relay includes a sub-network interface for communication with a sub-network, a plurality of backbone network interfaces for communication with a plurality of backbone networks, and a control unit for outputting data, which is received from a device included in the sub-network through the sub-network interface, through one of the backbone network interfaces. In the network relay, it is possible to fulfill various requests for communication quality by connecting the sub-network with the plurality of backbone networks.

    摘要： A method for communication between first and second coordinator-based wireless networks connected through a backbone network is provided. The method includes receiving a frame indicating data transmission containing information needed for remote channel time allocation (CTA) from a repeater connecting the second coordinator-based wireless network with the backbone network, sending a remote CTA frame in order for the repeater to request CTA from the coordinator within the second coordinator-based wireless network, and receiving a data frame originated from the first coordinator-based wireless network and then provided by the repeater during assigned channel time.

    摘要： A method of negotiating channel sharing between adjacent cells when there are a plurality of cells in a power line communication (PLC) network. The method includes attempting to negotiate the channel sharing during a minimum contention access period (CAP) which starts after a maximum beacon period ends and ends before a CAP of each PLC cell ends, wherein the maximum beacon period indicates a maximum size that a beacon frame in a super-frame transmitted from a coordinator of each PLC cell can have. When an attempt to negotiate the channel sharing is made using this method, interference does not occur during channel sharing negotiation, and effective channel sharing can be achieved, thereby eliminating interference between adjacent cells.

    摘要： A method of joining a cell by using a proxy coordinator. The method of joining a cell by using a proxy coordinator includes requesting a second device to operate as a proxy coordinator from a first device positioned out of a beacon frame reachable area of the cell, transmitting a time period to operate as the proxy coordinator allocated by a coordinator of the cell, informing the first device that the second device can operate as the proxy coordinator, transmitting a cell join request to the proxy coordinator from the first device through the second device, and transmitting a beacon frame including time allocation information from the coordinator to the first device through the second device.
