Abstract
With the rapid development of Internet of Things (IoT) technology and the explosive growth of data scale, traditional static resource scheduling methods can no longer meet the dynamic and heterogeneous requirements of IoT big data stream processing. This paper proposes an adaptive resource scheduling method based on deep reinforcement learning, which achieves intelligent resource scheduling decisions in IoT environments by constructing multi-level state space models, designing intelligent action spaces, and multi-objective reward functions. Experiments were conducted based on three typical application scenarios: smart cities, industrial IoT, and smart grids, establishing large-scale testing environments containing over 28,000 devices. Results demonstrate that compared to traditional scheduling methods, the proposed method achieves improvements of 42.3%-84.0% in response time, 56.7%-70.2% enhancement in system throughput, 34.1%-50.1% improvement in resource utilization, and 50.2%-60.3% enhancement in energy efficiency. During 18 months of actual deployment, cumulative operational cost savings reached 101.8 million yuan, with a payback period of only 1.8 years. Long-term stability testing shows that the algorithm processed 1.52 billion scheduling decisions during 30 days of continuous operation, with performance fluctuations controlled within 6.4%, demonstrating excellent convergence and robustness. The research findings provide theoretical foundations and technical support for intelligent resource management in IoT big data stream processing, holding significant importance for promoting the industrial application of IoT technology.
