基于近似Shapley值的边缘合作供给策略

Abstract: 】To address issues such as resource mismatch, load bottlenecks, and service instability caused by demand fluctuations and large-scale bursty tasks in mobile edge computing, a cooperative supply strategy based on approximate Shapley values (ASVC) is pro posed. First, a task allocation model based on bidirectional preference matching is constructed, which considers both the performance requirements of user tasks and the resource status of edge nodes. The Gale-Shapley algorithm is used to achieve optimal supply-demand matching. Second, to reduce the computational complexity of Shapley value estimation during coalition formation, an adaptive sam pling-based optimization scheme is introduced. This approach significantly reduces the computation time of Shapley values while maintaining accuracy. Finally, task data is allocated according to the proportional contribution of each node, improving system fairness and resource utilization efficiency. Simulation results show that, compared with existing algorithms, the proposed ASVC algorithm improves service quality, delay control, task completion rate, and system load balancing by approximately 27.8%, 31.0%, 30.8%, and 21%, respectively.
