In the development and application of the space-air-ground integrated network (SAGIN)

the intricate network structure and varied resources significantly affect the service capabilities of SAGIN. It is a challenge in the popularization of SAGIN to allocate and optimize resources to improve the performance in heterogeneous networks. Firstly

the architecture and functions of SAGIN were introduced. Subsequently

several typical issues in resource optimization were summarized and analyzed

along with the common performance objectives

modeling and optimization methods. Finally

the challenges in network optimization were analyzed

and the future research direction in this field was discussed.
