  author={Ning Zhang and Shan Zhang and Peng Yang and Omar Alhussein and Weihua Zhuang and Xuemin Shen},
  journal={IEEE Communications Magazine},
This article proposes a software defined spaceair- ground integrated network architecture for supporting diverse vehicular services in a seamless, efficient, and cost-effective manner. First, the motivations and challenges for integration of space-air-ground networks are reviewed. Second, a software defined network architecture with a layered structure is presented. To protect the legacy services in the satellite, aerial, and terrestrial segments, resources in each segment are sliced through… CONTINUE READING
