摘要
Cell selection and data offloading are the keys to obtaining MCS services with low sensing cost and low data processing delay. Due to the spatiotemporal correlation between data and the local-area coverage of edge servers, cell selection and data offloading will affect each other and require co-optimization. To achieve the co-optimization, we design the method OptInter based on the hierarchical reinforcement learning. OptInter can realize the interactive training between cell selection model and data offloading model. Finally, we evaluate our proposed method based on four datasets, each of which composited by real-world (e.g. NO $_{2}$ concentration, AQI value, Didi order, and Didi trajectory) data and simulated data. Compared with the four baseline methods (e.g., OptMOEA/D, OptStageCD, OptStageDC and OptWeight), the comprehensive performance of our proposed method can be improved by 11.83%, 20.48%, 10.14% and 42.27% on average, respectively.
