Analysis of Offloading Computation in Mobile Edge Computing (MEC): A Survey

Smartphones have made resource-intensive mobile applications indispensable in everyday life. To meet predetermined requirements and lighten the weight of such challenges brought on by the swift expansion of such serving technologies, distributed mobile edge computing (MEC) was developed to bring compute environments closer to end-users, frequently in a single step. To bridge the gap between the two, offloading techniques have been developed in the literature to shift resource-intensive tasks from mobile devices to nearby servers. There are many new concerns in the MEC context that make compute offloading problems more complex than ever before. These include the inherent software and hardware heterogeneity, constraints, ecosystem dynamics, and stochastic behaviour. The research also took into account a number of indicators relevant to computation offloading strategies in MEC. In this research, we provide a review of computation offloading strategies in the MEC setting in order to identify existing methods on this important topic and to raise unresolved challenges. The survey concludes with a case study illustrating MEC's applicability in the medical field.
