摘要： A communication method of a coordinator in a bidirectional event transmission sensor network comprising a sensor node and the coordinator is provided. The method includes sensing, in an uplink section, whether a signal having energy greater than or equal to a predetermined magnitude is received, the signal indicating occurrence of an uplink event detected by the sensor node, and transmitting, to the sensor node in a downlink section, a synchronization packet that is used for receiving the uplink event or for transmitting a downlink event in response to the coordinator detecting the downlink event or sensing the signal having energy greater than or equal to the predetermined magnitude in the uplink section. The bidirectional event transmission sensor network has a structure of a super frame that includes at least one standby slot (SS) including the uplink section and the downlink section.

摘要： A cognitive radio-based wireless communication system and an air interface method in a physical layer and a data link layer, which constitute a cognitive radio-based next-generation wireless communication system. The air interface method for wireless communication in the cognitive radio-based wireless communication system of the present invention is provided in the cognitive radio-based wireless communication system including a base station system and a plurality of mobile station systems. The base station system and a certain mobile station system communicate with each other using an overlay method that uses a spectrum hole. The base station system and the mobile station system switch from the overlay method to an underlay method to communicate with each other when a paying user having high priority performs communication using the spectrum hole.
