Abstract

The invention relates to a joint task offloading and resource allocation method in a mobile edge computing network, belonging to the fields of wireless communication and mobile edge computing. The method includes: the UE generates a new computing task, and sends a task offloading request to the MEC server; the MEC server collects computing offloading request information sent by all user terminals in this time slot; matches the user computing task with the MEC server resource for the first time to form an initial Unload the policy set, calculate the value of the initial objective function; find the minimum objective function value and the user who obtains the optimal objective function value. Update the unloading decisions of all users, and judge whether the obtained optimal objective function is not less than the last objective function value is established, and if it is established, output the unloading decision, channel allocation matrix and optimal computing resources. The invention reduces the cost of user offloading, saves the total cost of mobile users; can accept more computing offloading tasks, and improves the task execution efficiency of the system.

Description

technical field [0001] The invention belongs to the field of wireless communication and mobile edge computing, and relates to a joint task offloading and resource allocation method in a mobile edge computing network. Background technique [0002] The emergence of mobile edge computing provides an effective solution for resource-constrained mobile devices. Mobile devices can offload all or part of the computing-intensive tasks to mobile edge computing servers (Mobile Edge Computing, MEC) with relatively rich computing resources through wireless channels to reduce local processing task delay and energy consumption. However, performing calculation offloading may bring additional transmission delay and energy consumption, and determining the optimal offloading decision is a research focus in MEC networks. In addition, radio resources and computing capacity of MEC servers are limited resources, and radio and computing resources are provided to user equipment (User Equipment, UE)...
