In view of the poor forwarding and cooperation ability of the current AD-Hoc communication network,which leads to the poor communication packet delivery status of each node in the gateway and long end-to-end delay,the collaborative interface of the gateway based on microservice architecture is designed in the 5G environment to realize the dynamic collaborative work of microservices.The sliced life cycle management module of 5G gateway is constructed,the loose-coupled collaborative service cluster structure at the back end of the microservice architecture is designed,and the loose-coupled collaborative service configuration information of each component is obtained to realize the gateway configuration.Calculate the communication range of AD-Hoc network in 5G environment,adjust the node density,access the network through the AD-Hoc communication gateway,calculate the expected utility of the dynamic gateway in a certain time slot,and realize forwarding and cooperation in the balanced game state of the dynamic gateway.According to the test results,the maximum end-to-end delay is only 3 s,indicating that the designed gateway has good forwarding and collaboration capabilities.
