ABSTRACT:
This invention relates to cognitive radio based wireless communications of dynamic spectrum access networks, and more particularly to a method of addressing radio frequency sensing control and dynamic frequency selection control. A method called Cognitive Dynamic Frequency Hopping that is based on the selective Simultaneous Sensing and Data Transmissions is described. The Cognitive Dynamic Frequency Hopping method is further facilitated by a collision avoidance technique. The described method satisfies both reliable and timely RF sensing for guaranteeing licensed user protection, and QoS satisfaction for services of the dynamic spectrum access systems.
