Nowadays, the development of edge computing technologies enables the deployment of time-sensitive and large-data-volume services on infrastructure, which significantly promotes the development of the applications like connected vehicles and the intelligent industry. Together with the development of mobile communication technologies(e.g., 5G), edge computing architecture is gaining more and more traction, leading people to imagine the possibility of deploying time-critical mobile services on edge to reduce computational power requirements on mobile devices, especially in application scenarios like autonomous driving or unmanned aerial vehicles (UAVs). However, in actual practice, the deployment of time-critical mobile services on the edge server still has many challenges, especially the communication latency.
