摘要
为解决网络边缘服务器超负荷的问题,提出一个基于停车协同的边缘计算任务卸载框架.在该框架下,服务提供商利用停车场中停靠车辆的空闲计算资源扩展网络边缘服务器的计算能力,停靠车辆协同执行服务提供商卸载的计算任务,从而减少超负荷.为激励停靠车辆执行卸载的计算任务,设计一个基于契约论的激励方案,不仅能够使服务提供商的效益最大化,同时能够满足停靠车辆的效益.基于真实数据集的实验仿真结果证明所提的激励方案有效.
To improve the performance of edge computing(EC)servers,an edge computing offloading framework of parked vehicular collaboration was proposed.Under this framework,the service provider uses the idle computing resources of the parked vehicles in the parking lot to expand the computing capacity of the edge server of the network,and the parked vehicles cooperate to perform the computing tasks unloaded by the service provider,thus reducing the overload.To stimulate parked vehicles to participate in computation offloading,an incentive scheme based on contract theory is designed,which can not only maximize the benefits of EC service providers,but also enhance the utilities of the parked vehicles.Experimental simulation results based on a real dataset demonstrate the effectiveness of the proposed incentive scheme.
