摘要

随着智能物联技术与5G/6G通信技术的深度融合，卫星边缘计算（SatEC

satellite edge computing）凭借空天协同计算网络，为地面网络覆盖薄弱区域提供了新型算力服务。然而，SatEC系统面临星地动态资源分配失衡与多维时空约束下任务优先级控制不足的双重挑战。现有方法在分层决策、时空特征提取及任务紧急度量化映射方面存在缺陷，导致时敏任务处理效率受限。为此，提出了一种基于自注意力时间卷积网络的多智能体深度强化学习算法。该算法通过构建多智能体架构实现任务优先级排序与资源分配的联合优化，采用融合时空特征的混合神经网络精准提取星地协同场景的动态关联特性，并建立基于概率模型的动态调度机制，协同优化时延约束与任务完成率。仿真结果表明，相较于基准算法，该算法在任务完成率与时延控制方面均实现了显著的提升，验证了其在复杂卫星边缘计算场景中的有效性与优越性。

Abstract

With the deep integration of intelligent Internet of things technology and 5G/6G communication technology

satellite edge computing (SatEC) offers new computational services to areas with weak terrestrial network coverage through its aerospace collaborative computing network. However

the SatEC system faces dual challenges of unbalanced dynamic resource allocation between satellite and ground and insufficient task priority control under multi-dimensional spatiotemporal constraints. Existing methods have defects in hierarchical decision-making

spatiotemporal feature extraction

and task urgency quantification mapping

which limit the efficiency of time-sensitive task processing. To address this problem

a multi-agent deep reinforcement learning algorithm based on self-attention temporal convolutional networks was proposed in this paper. The algorithm achieved joint optimization of task prioritization and resource allocation by constructing a multi-agent architecture

employed a hybrid neural network integrating spatiotemporal features to accurately extract dynamic correlation characteristics of satellite-ground collaboration scenarios

and established a dynamic scheduling mechanism based on a probabilistic model to synergistically optimize latency constraints and task completion rates. Simulation results show that

compared with the baseline algorithm

the proposed algorithm achieves significant improvements in both task completion rate and delay control

demonstrating its effectiveness and superiority in complex satellite edge computing scenarios.
