Abstract

The invention provides a joint computing unloading method and device based on an energy collection technology, and the method comprises the steps: collecting the real-time information of a mobile terminal and an edge server in each preset time slice, and building a virtual energy queue of each mobile terminal according to the real-time information of the mobile terminal; Constructing a task execution cost model, a terminal energy consumption model and an energy collection model; Constructing a Lyapunov drift and penalty function according to the real-time information of the edge server, the real-time information of all mobile terminals, the constructed task execution cost model, the terminal energy consumption model and the energy collection model, and further obtaining an objective function; And taking the virtual energy queue as a queue needing to be stabilized, and solving a calculation unloading decision in the current time slice by minimizing an objective function. The technical effects of effectively reducing the average execution cost of the tasks and the abandoning rate of the tasks and improving the performance of an edge computing system are achieved.

Description

technical field [0001] The present invention relates to the technical field of mobile edge computing, in particular to a joint computing offloading method and device based on energy harvesting technology. Background technique [0002] With the rapid iterative update of mobile communication technology and the explosive popularity of various mobile smart terminals, the mobile Internet business has entered a stage of rapid development. According to the estimate of Cisco Global Cloud Index, by 2019, 45% of the data generated by IoT devices will be stored, processed and analyzed at the edge of the network, and the total data traffic of global data centers is expected to reach 10.4 zettabytes (Zettabyte, ZB). ). At the same time, according to the forecast of Cisco Internet Business Solutions Group, by 2020, there will be nearly 50 billion wireless devices connected to the network. [0003] In the existing technology, the traditional mobile cloud computing (Mobile Cloud Computing...
