Abstract
Computation offloading is becoming a promising technology that can improve quality of service for mobile users in mobile edge computing. However, it becomes much difficult when there are multi-cloudlet near to the mobile users. The resources of the cloudlet are heterogeneous and finite, and thus it is challenge to choose the best cloudlet for the multi-user. The issue for multi-user in multi-cloudlet environment is well-investigated in this study. Firstly, we establish a multi-objective optimization model with respect to time consumption and energy consumption of mobile devices. Moreover, we devise a multi-objective computation offloading method based on improved fast and elitist genetic algorithm for selecting the optimal offloading strategies. Finally, compared with other methods, numerous experiments proved that our proposed method have advantages in effectiveness and efficiency.
