“…In problem solving, some scholars use traditional methods. Thai et al [6] proposed a generic architecture for cloud edge computing with both vertical and horizontal service computing nodes, formulated as a mixed-integer nonlinear programming problem, proposed an approximation algorithm to iteratively obtain the optimal solution using a branch-and-bound method to minimize the system computation and communication costs. Cui et al [7] made a trade-off between energy consumption and latency to meet the user requirements of different IoT applications, formalized the problem as a constrained multiobjective optimization problem, and found the optimal solution by an improved fast elite non-dominated ranking genetic algorithm.…”

“…At present, researchers have conducted a lot of research on the offloading decision problem, such as seeking the optimal solution after formulating the problem based on traditional algorithms [6][7][8][9][10], maximizing the reward to make appropriate decision actions based on reinforcement learning algorithms [11][12][13][14], etc. However, the above algorithms do not take the dynamic and predictable nature of the task during task offloading into account, thus they may produce unreasonable offloading decisions, resulting in degradation of the task offloading performance.…”

“…Ruan et al [27] assumed an energy management infrastructure as a cloud model comprising three tiers, and optimized for latency using joint optimization between Stackelberg and Lyapunov-based pricing and energy demand. Thai et al [28] proposed vertical and horizontal offloading models between edge to cloud and edge to edge, and used an approximation algorithm to minimize the cost.…”

“…However, the use of Cloud Computing (CC) for task offloading of the end-devices can generate two major issues: high transmission latency and capacity-demand mismatch, i.e., resource overprovisioning, which leads to resource and energy waste [4]. To mitigate this, the Edge Computing (EC) approach, which pushes computing capabilities at the Edge of the network, is being rapidly adopted and seems promising in terms of achieving the ambitious millisecond-scale latency required in various 5G and IoT applications [5].…”
