Abstract
The present invention involves a method for distributed dynamic spectrum allocation performed by a source device and the source device, a method for dynamic spectrum allocation performed by a power node and the power node, the method including sending to appropriate power nodes a query message indicating that the source device requests to find an idle licensed spectrum; receiving from the appropriate power nodes a query response message indicating licensed spectrums; and determining whether the licensed spectrums are idle and selecting an idle licensed spectrum from the licensed spectrums to be used. In this way, the provided method may implement distributed dynamic spectrum allocation without using a central authority.
