Apparatus and method for managing channel resource

An apparatus for managing a channel resource to transmit a data frame in a wireless network, the apparatus comprising:

• a setting unit that sets a channel hopping sequence and a channel hopping offset value which are to be used;
• a time slot assignment unit that assigns a time slot;
• a time slot and frame dividing unit that divides the time slot into a plurality of subslots, and divides a data frame into a plurality of subframes;
• a channel selection unit that selects a channel for transmitting the plurality of subframes in the plurality of subslots, respectively, by using the channel hopping sequence, the channel hopping offset value, the index of the time slot, and the index of a subslot for transmitting a subframe.
