Analysis of Outage Probability and Average Peak Age of Information for LEOSAT-Enabled NTFPs

This paper presents a theoretical analysis for estimating the outage probability (OP) and the average peak age of information (APAoI) referred to an uplink communication between a networked tethered flying platform (NTFP) and a low-Earth orbit satellite (LEOSAT). Closed-form expressions are obtained for both the OP and the APAoI under an M/Geo/1/1 queueing model in realistic propagation conditions, including noise, path-loss attenuation, ionospheric scintillation, and Poisson-distributed satellite location. The analytical results, whose accuracy is checked by extensive Monte Carlo validations, are exploited to investigate the impact of the propagation parameters, of the number of satellites, and of their altitude on the performance of the NTFP-LEOSAT uplink connection.
