Abstract
A method and system for collaborative spectrum sensing in a cognitive radio network is provided. The method may include: receiving through a cognitive radio network a plurality of sensing results of availability of a channel, where the plurality of sensing results are generated by a corresponding number of vehicles within the cognitive radio network, respectively, where broadcasting of the plurality of sensing results is controlled based on positions of vehicles within the cognitive radio network; and determining whether the channel is available based on the plurality of sensing results. By using the method, the efficiency of collaborative spectrum sensing can be improved.
