摘要：
To solve the problem that the computing resources of ground equipment are not utilized effectively, the device-to-device (D2D) assisted task offloading in mobile edge computing-enabled satellite-terrestrial networks is studied. The utility maximization problem for all user equipment, service equipment, and the low earth orbit satellite is modeled and decomposed into two sub-problems, which are task offloading ratio optimization sub-problem and task offloading decision sub-problem. The analytical solution of the optimal task offloading ratio of D2D offloading problem and mobile edge computing offloading problem is obtained by the theoretical derivation, respectively. Besides, a matching game-based task offloading decision algorithm is designed and a joint optimization scheme of task offloading ratio and task offloading decision is proposed. The simulation results demonstrate that the proposed scheme has better performance than the reference schemes. © 2024 Beijing University of Posts and Telecommunications. All rights reserved.
