Interference Sources Localization and Communication Relationship Inference With Cognitive Radio IoT Networks

Zhao Niu, Tao Ma, Nina Shu, Hong Shan
2020 IEEE Access  
Therefore, in this paper, we investigate the problem of how to locate the interference sources and infer their communication relationships in the cognitive radio IoT (CR-IoT) deployment scenario.  ...  With the widespread application of Internet of things (IoT), the interference problem becomes more and more serious, which results in not only the poor network performance but also the increased energy  ...  It is also reasonable to suppose that the interference radio stations communicate with each other, but they cannot communicate with CR-IoT nodes.  ...
