Heterogeneous LoRaWAN & LEO Satellites Networks Concepts, Architectures and Future directions

Nowadays, Low Earth Orbit Satellites (LEO) regains much attention, especially where the satellites play the relay role in the communication networks and particularly for the internet of things networks. In this article, we emphasis on the deployment of the LEO satellite for IoT and on the correlation between LoRaWAN and LEO satellites networks. We first propose an IoT architecture based heterogeneous space and terrestrial integrated network. Then a novel architecture for LEO satellites remote monitoring based on the use of LoRaWAN modules for data plane and Software-Defined Networking for the control plane was suggested. Finally, some challenging open issues related to the use of SDN controllers in space are revealed.
