- Abstract:
-
In the network architecture of mobile edge computing, an offloading decision controller was introduced to balance the reduction of energy consumption and delay. This controller obtains the optimal offloading decision through an offloading decision optimization algorithm. A new ABC–FS algorithm was proposed by combining the artificial bee colony (ABC) algorithm and the artificial fish swarm (FS) algorithm. Additionally, a Gaussian decay function was introduced to transition the algorithm parameters from static to dynamic, and the inertia weight factor of the improved particle swarm optimization algorithm was incorporated, creating a multi-population hybrid intelligent optimization algorithm. Finally, an objective function that jointly optimizes delay and energy consumption was designed, and simulation experiments were conducted using Poisson probability. Simulation results show that the proposed offloading strategy optimization algorithm achieves faster convergence speed compared to several benchmark methods and effectively balances the reduction of total task offloading delay and total energy consumption in multi-access edge computing scenarios.
