WLAN SYSTEM COMMUNICATION METHID FOR COGNITIVE RADIO-BASED WLAN NETWORK

摘要

Candidate channel group is relayed in the collision that WLAN system communication means based on radio identification is arranged to reduce in a swap status candidate channel, and a kind of system is to improve performance. A kind of CR (cognitive radio) systems or an incumbent system are inserted into a CR beacon, including coexistence parameter group information, have the seller's special dimension for entering a WLAN beacon about the information in a UHF band channel. CR systems or incumbent system transmit CR beacons. One WLAN (WLAN) AP (entrance) manages and relays spectrum sensing information, including UHF (hyperfrequency) channel information by coexistence parameter group. Routing or transfer are related with QoS (service quality) by operation, due to sharing for coexistence parameter group.
