Embodiment Construction
[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0056] Based on the above purpose, the distributed cooperative spectrum sensing method based on the maximum and minimum distance clustering provided by the present invention is suitable for the cognitive UAV network, and the cognitive UAV network has a primary user P and N cognitive drones. Man-machine, its steps are:
[0057] Use the maximum and minimum distance clustering algorithm to divide the cognitive UAV into several clusters, and select the cluster head within the cluster;
[0058] Each cognitive UAV uses energy detection to obtain the perception information of the primary user P;
[0059] According to the clustering situation and the perception information of each cognitive UAV, two-step fusion is performed, so ...
