IoT数据敏感的工作流在线调度方法研究

IoT数据敏感的工作流在线调度方法研究摘要：

随着物联网技术和大数据技术的不断发展，越来越多的企业开始利用IoT数据来支持其业务流程。然而，这些数据通常是敏感的，需要进行保护，因此，如何在线调度IoT数据敏感的工作流变得非常重要。本文针对这个问题，提出了一种基于机器学习的在线调度方法，该方法可以在保证数据敏感性的同时，实现IoT工作流的高效调度。具体地，本文首先分析了IoT数据的敏感性，并介绍了目前常用的数据保护方法。然后，提出了一种新的机器学习算法，用于学习和预测IoT工作流的执行时间和资源需求。最后，设计了一个在线调度器，该调度器可以自适应地确定最优的调度方案，以满足不同的数据敏感性和性能要求。实验结果表明，这种基于机器学习的调度方法可以有效地提高IoT工作流的调度效率和资源利用率，同时能够满足数据敏感的保护要求。
