Mobile edge computing is a key technology for future 5G communication. Mobile edge computing helps to achieve the requirements of ultra-low latency, high energy efficiency, ultra-reliability, and ultra-high connection density for the new services of the fifth generation of mobile communication (5G). To solve multi-user intensive task scheduling problem under 5G cellular networks, this paper proposes a computation offloading strategy based on back propagation neural network. The genetic algorithm is used to optimize the weights and biases of the back propagation neural network, and the back propagation neural network model trained in advance is used to adaptively and jointly optimize the system energy consumption and time delay to generate the computation offloading results. Compared with the benchmark algorithm, the algorithm proposed in this paper can effectively reduce system overhead, meet the requirements of 5G environment for low latency and low energy consumption, and improve quality of service.
