Integral and crucial to performance of wireless sensor networks (WSNs), and specifically industrial wireless sensor network (IWSN) is stable, robust, reliable, and ubiquitous communications system. Though, wired communications system is suitable for industrial communications and is resilient to shadowing and multipath fading effects of industrial‐WSN environments, yet its wireless counterpart is a much preferred industrial communications technology due to reduced cost and high flexibility which it offers in comparison to wired communications. However, overcrowding of the industrial, scientific, and medical band, where IWSN is deployed together with other heterogeneous technologies, as well as resultant scarcity of usable frequency spectrum has restrained exclusive application of wireless technology for industrial communications. Nonetheless, cognitive radio (CR) has ability to increase spectrum utilization efficiency and channel capacity for industrial wireless communications (IWC) through opportunistic/dynamic spectrum access (DSA) technique. In this review article, we examine how DSA can benefit IWC through exploitation of new perspectives of white space definitions in the licensed bands as well as unlicensed bands. While discussing the potential of DSA for IWC, we have considered the unique characteristics of IWC as well as technical challenges and issues imposed by industrial‐WSN. Accordingly, we have suggested and proffered appropriate CR‐based solutions in mitigating some of the challenges where necessary.

工业无线通信，挑战和解决方案的回顾：一种认知无线电方法

对于无线传感器网络（WSN），特别是工业无线传感器网络（IWSN）的性能而言，不可或缺的关键是稳定，鲁棒，可靠且无处不在的通信系统。尽管有线通信系统适用于工业通信，并且能够抵抗工业WSN环境的阴影和多径衰落效应，但由于其成本较低且灵活性较高，因此其无线对等技术是首选的工业通信技术，与有线相比通讯。但是，工业，科学和医疗频段的拥挤状况（IWSN与其他异构技术一起部署）以及可用频谱的紧缺限制了无线技术在工业通信中的专有应用。尽管如此，认知无线电（CR）具有通过机会/动态频谱访问（DSA）技术提高工业无线通信（IWC）的频谱利用率和信道容量的能力。在这篇评论文章中，我们研究了DSA如何通过利用许可频段和非许可频段中空白定义的新观点来使IWC受益。在讨论DSA对于IWC万国表的潜力时，我们考虑了IWC万国表的独特特征，以及工业级WSN带来的技术挑战和问题。因此，我们在必要时建议并提供了适当的基于CR的解决方案来缓解某些挑战。
