A communication method in an environment in which a plurality of communication networks can coexist is provided to prevent interference and collision by establishing a plurality of sub-bands consisting of narrow bands when a plurality of heterogeneous networks transmit beacons. Available channels are searched to open a communication network(S80). Whether homogeneous networks were opened is confirmed(S81) before directly opening the communication network. If the homogeneous networks are discovered, the service level(for example, interference sensitivity level) which an available coordinator transmits is confirmed(S82). In case the sensitivity level provided by the homogeneous networks is identical to or higher than the service level desired to be provided, the negotiation with the coordinator is started, scheduling information is received, and a service transmitting/receiving operation is performed(S83). In case the sensitivity level provided by the homogeneous networks cannot be changed(S84), the channels are searched again(S85). |
