Considering the global demands on Internet of things (IoT), and the limitation of constructing base stations for the terrestrial IoT, the satellite IoT approach is a realizable and powerful supplement to the terrestrial IoT. Meanwhile, in order to dynamically access the available terrestrial and satellite networks, IoT terminals may have the ability of accessing both the terrestrial IoT and the satellite IoT, leading to great challenges on the access-control of the IoT. In this paper, we design a satellite-terrestrial integrated architecture for the IoT relying on the software defined network (SDN). Moreover, based on this architecture, we further propose a dynamic channel resource allocation algorithm to control the access of the IoT terminals with different priorities. Simulation results show that the demands on the probabilities of successful access of IoT terminals with various priorities can be simultaneously met if the access of the IoT terminals are well controlled. |
