Research on Mobile Edge Computing Pricing and Offloading Technology for Intelligent Inspection Service

In the scenario of power Internet of things,the smart inspection device needs to process a large amount of sensing data during the inspection process.Due to the limited battery capacity and computing resources of the inspection device,it may cause some problems,such as long fault location time and slow response processing.In order to improve service quality of the inspection device,this paper uses the Mobileedge computing(MEC)server to provide computing services for inspection device and adopts device-todevice(D2D)communication mode to cooperate to complete the computing task.Considering the computing power of MEC server,a unified resource pricing scheme is proposed,and the stackelberg game is formulated to determine the data computing scheme of the inspection device and the resource pricing scheme of the MEC server.The simulation results show that the proposed scheme can effectively reduce computational delay of smart inspection device by 40%compared with only using local computing scheme.
