- Abstract
- The present invention provides a method and system for performing distributed channel sensing in which channel information is collected by performing channel sensing according to a channel sensing priority which is determined according to a relative position of a cell to which a wireless connection device belongs from among a plurality of cells which logically partition the zone of the wireless network, and thus the overhead of the channel sensing which is generated in a cognitive wireless multi-hop network environment is reduced, and the transmission failure which occurs when the wireless connection device detects frequencies is reduced.
