Title: ON PARETO-OPTIMAL SAGIN SYSTEMS RELYING ON SPECTRUM-HARMONIZATION

Speaker: Lajos Hanzo, University of Southampton

Space, Air, Ground Integrated Networks (SAGINs) rely on terrestrial, UAV-aided, airplane-assisted as well as satellite-based global coverage-solutions, which pave the way for seamless next-generation service provision across the globe. However, these terrestrial, UAV-aided, airplane-assisted as well as satellite links exhibit drastically different propagation properties, which naturally lend themselves to Pareto-optimal network-slicing. 

The 5G systems have been designed for fully-fledged eMBB, mD2D and URLLC services, while their 6G counterparts will further improve these tight specifications. However, their small-cell-based coverage area will remain limited to urban scenarios of high tele-traffic density for years to come. Hence the emerging mobile satellite networks and aeronautical ad-hoc networks (AANETs) will have to be harnessed for covering all remote low-traffic areas. But their overall performance will inevitably remain more limited.

To harmonize the above-mentioned conflicting requirements, we conclude with the joint Pareto-optimization of the associated conflicting performance metrics of throughput, transmit power, latency, error probability, hand-over probability and link-lifetime. Explicitly, sophisticated multi-component system optimization is required for finding the Pareto-front of all optimal solutions, where none of the above-mentioned metrics can be improved without degrading at least one of the others...
