This report contains a description of the proposed network composed of a Nanosatellite swarm portion and a Flying Ad-hoc Networks (FANETs) UAV portion. Section 1 contains a description of the state of the art about Nanosatellites, in particular about Nanosatellite missions and hardware components, followed by a brief explanation about satellite constellation design. After that, a description of the routing and security challenges and the possible solutions in literature is reported. Finally, the proposed Nanosatellite-DTN Network, the simulation platform, and the obtained results are illustrated in details. Section 2 regards Flying Ad Hoc Networks (FANETs). FANETs are a rising topic in literature, attracting both scientific and commercial interest. In this WI, the communication issues among FANETs and a Ground Control Station (GCS) are investigated, when both user and Command and Control ( ) data are sent via a random access satellite channel. The focus is put on the mobility model, on the intra-swarm and extra-swarm communications needs, as well as on lightweight and flexible protocol stacks enabling a fast data delivery and an easy tuning of the available parameters in the use-case under consideration. A NS3-based simulator has been built and numerical results are presented, assessing the achievable performance level. Section 3 briefly presents channel modelling due to local environment effects that may be applied for both Nanosatellite/Ground Station and GEO satellite/UAV links taking into account the different attenuations at the different considered frequency bands.
