PURPOSE: A method of transmitting a home PNA(Phoneline Networking Alliance) data frame is provided to integrate a power line network with a telephone line network, thereby implementing smooth communication between unstable nodes via a relay node according to a network state by noise generated from a power line. CONSTITUTION: A network decides whether a connection state of a node to be received with data is good by using network state information. If not, the network selects an optimum relay node, and adds an address and a control bit of the relay node to a frame to be transmitted, then transmits the frame. The network receives the frame in the relay node, and checks a control bit of the frame to decide whether an additional address exists. If so, the network remakes a frame removing a relay destination address, and transmits data to a destination node address. |
