Method for supporting multi-channel in wireless mesh network

A method for supporting a multi-channel in a wireless mesh network is provided to enhance channel efficiency by equally distributing the amount of data transmitted in each data channel every period. A method for supporting a multi-channel in a wireless mesh network includes the steps of: sharing traffic information of all nodes by transmitting and receiving an ATIM(Ad hoc Traffic Indication Messages)(200), defined as a phase 1(130); deciding own channel by transmitting and receiving a CHS(CHannel Selection) message, defined as a phase 2(140); transmitting and receiving a re-transmission message in a case of the CHS message not received, corresponding to the ATIM, defined as a phase 3(150); and moving to the decided channel and transmitting data.
