Cognitive radio is becoming an increasingly important component of Internet of Things technologies, because it improves spectrum efficiency and provides a way to overcome the challenge of excessive demand for wireless communications. Research and development of cognitive radio communication systems are timely and helpful. Recently, Zheng et al. proposed a network stability-aware clustering protocol for cognitive radio sensor networks. In this letter, we discuss its fatal flaws, as well as ways to overcome them.
