摘要：
To address the problem of load imbalance among edge servers and quality of service degradation caused by dynamic changes of user locations in mobile edge computing networks, a mobility aware edge service migration algorithm was proposed. Firstly, the optimization problem was formulated as a mix integer nonlinear programming problem, with the goal of minimizing the perceived delay of user service request. Then, the delay optimization problem was decoupled into the edge service migration and edge node selection sub-problems based on the Lyapunov optimization approach. Thereafter, the fast edge decision algorithm was proposed to optimize the resource allocation and edge service migration under a given radio access strategy. Finally, the asynchronous optimal response algorithm was proposed to iterate out the optimal radio access strategy. Simulation results validate the proposed algorithm can reduce the perceived delay under the service migration cost constraint while comparing with other existing algorithms. © 2020, Editorial Board of Journal on Communications.
