PURPOSE: An overhead distribution method of a recognition wireless network is provided to distribute a control packet by using a GCC (Group Control Channel) by grouping channels. CONSTITUTION: Available channels are classified into a plurality of groups (S210). The classified channel groups are assigned to a transmission node and a reception node (S220). GCCs are assigned to each group (S240). A packet is distributed between the transmission node and the reception node by using the GCC assigned to teach group (S270). The each ID in the node is assigned. The ID includes a group identifier. [Reference numerals] (AA) Start; (BB) End; (S210) Group classification step of dividing available channels into a plurality of groups; (S220) ID assignment step of assigning each intrinsic number(ID) per node; (S230) Group assignment step of assigning the member groups of each transceiving node based on a value which divides the intrinsic number(ID) by the number of groups(k); (S240) Channel assignment step of assigning one group control channel(GCC) per group; (S250) Are reception node and transmission node assigned in the same group?; (S260) Same group packet transmission step of exchanging control packets in a negotiation window section, selecting a data channel to be used, and transmitting a data packet when the reception node and transmission node are assigned in the same group; (S270) Different group packet transmission step of exchanging control packets to being changed into the GCC of a group, to which transmission node and reception node are belonged, selecting a data channel to be used, and transmitting a data packet when the reception node and transmission node are assigned in different groups |
