Intelligent dynamic spectrum resource management, which is based on vast amounts of sensing data from industrial IoT in the space-time and frequency domains, uses optimization algorithm-based decisions to minimize levels of interference, such as energy consumption, power control, idle channel allocation, time slot allocation, and spectrum handoff. However, these techniques make it difficult to allocate resources quickly and waste valuable solution information that is optimized according to the evolution of spectrum states in the space-time and frequency domains. Therefore, in this paper, we propose the implementation of intelligent dynamic real-time spectrum resource management through the application of data mining and case-based reasoning, which reduces the complexity of existing intelligent dynamic spectrum resource management and enables efficient real-time resource allocation. In this case, data mining and case-based reasoning analyze the activity patterns of incumbent users using vast amounts of sensing data from industrial IoT and enable rapid resource allocation, making use of case DB classified by case. In this study, we confirmed a number of optimization engine operations and spectrum resource management capabilities (spectrum handoff, handoff latency, energy consumption, and link maintenance) to prove the effectiveness of the proposed intelligent dynamic real-time spectrum resource management. These indicators prove that it is possible to minimize the complexity of existing intelligent dynamic spectrum resource management and maintain efficient real-time resource allocation and reliable communication; also, the above findings confirm that our method can achieve a superior performance to that of existing spectrum resource management techniques.
智能动态频谱资源管理基于来自工业物联网在时空和频域的大量传感数据,利用基于优化算法的决策来最小化干扰水平,如能耗、功率控制、空闲信道分配、时隙分配和频谱切换。然而,这些技术难以快速分配资源,并且浪费了根据时空和频域中频谱状态的演变而优化的宝贵解决方案信息。因此,在本文中,我们提出通过应用数据挖掘和基于案例的推理来实现智能动态实时频谱资源管理,这降低了现有智能动态频谱资源管理的复杂性,并实现了高效的实时资源分配。在这种情况下,数据挖掘和基于案例的推理利用来自工业物联网的大量传感数据来分析现有用户的活动模式,并通过按案例分类的案例数据库实现快速资源分配。在本研究中,我们确认了许多优化引擎操作和频谱资源管理能力(频谱切换、切换延迟、能耗和链路维护),以证明所提出的智能动态实时频谱资源管理的有效性。这些指标证明,有可能最小化现有智能动态频谱资源管理的复杂性,并维持高效的实时资源分配和可靠通信;此外,上述发现证实我们的方法能够实现优于现有频谱资源管理技术的性能。
