    摘要:

    多接入边缘计算(MEC)中的计算卸载问题已经成为了当前研究的热点之一.目前的计算卸载方案仅考虑云、边、端结构中的计算卸载问题,而未考虑到其公、私有云的属性.本文提出了一种新的计算卸载方案,该方案考虑了边缘计算中公有云与私有云之间的关系,将公有云作为了私有云资源的补充,可以缓解由于私有云资源局限性带来的算力不足问题;并通过建立双层Stackelberg博弈来解决计算卸载问题.对公有云、私有云、以及用户的策略和收益进行了分析,求出了各参与人的最优策略,证明了双层博弈的纳什均衡解的存在性及唯一性.仿真结果和分析也验证了基于双层Stackelberg博弈的计算卸载方案的可行性,且相较基于单层Stackelberg博弈的卸载方案更高效,更适合可扩展的边缘计算的环境.

    Abstract:

    The computation offloading problem of Multi-access Edge Computing (MEC) has become one of the hot topics in current research. The current computation offloading scheme only considers the computation offloading problem in the Cloud,Edge and End structures, but does not consider the attributes of the public and private clouds. In this paper, a novel computation offloading scheme is proposed, which considers the relationship between public cloud and private cloud in Edge Computing, and uses public cloud as a supplement to private cloud resources. In this scheme, the insufficient computing power caused by the limitations of private cloud resource can be alleviated; And a two-layer Stackelberg game is established to solve the computation offloading problem. The optimal strategies of each player are obtained, and the existence and uniqueness of the Nash equilibrium solution of the two-layer game are proved. The simulation results and analysis also show that the feasibility of computation offloading scheme based on the two-layer Stackelberg game is proved, and the computation offloading scheme based on the two-layer Stackelberg game is more efficient and more suitable for Edge Computing environment than the computation offloading scheme based on single-layer Stackelberg game.
