In order to meet the business requirements of various application scenarios in the 5G network era, a mobile edge computing node deployment algorithm for 5G network is designed. The 5G network-oriented mobile edge computing network architecture including network capability and platform capability is analyzed. The internal mobile edge computing platform adopts the clonal node identification method based on channel information to improve the security of mobile edge computing nodes. On this basis, the service attributes, wireless sites and computer room resource views are combined with the service requirements. The possible deployment location of mobile edge computing nodes is obtained, and the virtual network function of the network composed of nodes is deployed by using the improved genetic simulated annealing algorithm to realize the deployment of mobile edge computing nodes for 5G network. The experimental results show that the algorithm can effectively avoid clone node attacks, the different characteristics of each mobile edge computing application case show a good state, and the end-to-end delay of service requests in the network constructed by node deployment can be reduced by about 75% with the increase of the number of general service nodes.
