Resource Allocation Method for Priority Task in Mobile Edge Computing
摘要
In mobile edge computing,most of existing resource allocation methods allocate computing resources according to the time that tasks request computation offloading,without considering task priority in practical applications.To meet computing requirements in such cases,this paper proposes a resource allocation method for priority tasks.This method assigns priority to each task based on their average processing value,and implements weighted allocation of computing resources for tasks of different priorities.It ensures high-priority tasks obtain sufficient computing resources while the total time and energy consumption for completing all tasks are reduced.Thus the Quality of Service(QoS) is improved. Simulation results show that,compared with the method of evenly allocating computing resources,the method of allocating resources according to the amount of task data and the method of placing all tasks on mobile terminals,the calculation delay of this method is reduced by 83.76%,15.05% and 99.42% respectively,and the energy consumption is reduced by 84.78%,17.37% and 87.69% respectively.
