Task unloading method in MEC system based on SWIPT

The invention belongs to the technical field of mobile communication, and relates to a method for offloading tasks in an MEC system based on SWIPT, which comprises the following steps: considering an SWIPTT-MEC system consisting of a plurality of terminal devices and a plurality of base stations; respectively establishing a task model, a communication model, a calculation model and an energy collection model; in order to solve the problem of system income maximization, a supply and demand interaction optimization model based on a buying and selling game is established; the terminal equipment purchases communication resources from the base station according to own calculation requirements and energy requirements, and a buyer income maximization problem is established; different calculation and communication resources are provided for equipment through a dynamic quotation base station, a seller income maximization problem is established, and an optimal unloading decision of a training time slot is calculated th
