Satellite Based Sensor Networks with Energy-Harvesting-Aided Earth Terminal

In this paper, we investigate the performance of a satellite based sensor network with energy-harvesting-aided earth terminal. Specifically, by assuming that the earth terminal first harvests energy from a dedicated power beacon (PB) and then sends information to the satellite, we derive the closed-form expressions for the throughput of satellite based sensor network by evaluating the outage probability (OP) and ergodic capacity for delay-limited and delay-tolerant transmission modes, respectively. A comprehensive simulation results are carried out to verify the theoretical derivations, and provide intuitive and practical insights into the effect of various parameters on the performance of considered system.
