Research on Green Offloading and Processing Scheme for Multiple Applications
Mobile Edge Computing(MEC)is widely used in the new Internet of Things due to its low delay,low power consumption and high system capacity.To further make full use of the computing resource and reduce the power consumption,the scheme of computation offloading,computation processing sequence and power allocation are studied in green MEC system with D2D assisted offloading.To achieve green offloading,total power minimization of the terminal devices is put forward which considers many different application requests.To solve the original NP-hard problem,the Green Offloading and Application Processing Sorting Algorithm(GOAPSA)is proposed based on greedy method and bubble sort method.Simulation results show that the proposed algorithm can reduce the total system power consumption and increase system capacity by adjusting flexibly the processing sequence of applications and transmission power allocation and using D2D-assisted offloading.
