Resource Caching and Task Migration Strategy of Small Cellular Networks under Mobile Edge Computing

As computing-intensive mobile applications become increasingly diversified, devices’ computing power is hard to keep up with demand. Mobile devices migrate tasks the Edge Computing (MEC) platform and improve performance of task processing through reasonable allocation caching resources on platform. Small cellular networks (SCN) have excellent short-distance communication capabilities, combination MEC SCN a promising research direction. This paper focuses minimizing energy consumption for migration in small proposes optimization strategy resource by combining optimal stopping theory decision-making. Firstly, process device finding required formulated as problem. Secondly, we prove an rule’s existence, obtain threshold, compare it consumption. Finally, best selected task. In simulation experiment, has lower average higher data execution efficiency distance efficiency, which improves 10% ∼ 60%.
