Constellation Design of LEO Satellite Internet of Things with QoS Provision

Low earth orbit (LEO) satellite Internet of Things (IoT) has been recognized as a pivotal element within the realm of sixth-generation (6G) non-terrestrial networks (NTN), aimed at delivering ubiquitous connectivity. Due to the low orbit altitude and fast movement speed, a massive number of satellites are needed to form a satellite constellation, resulting in substantial construction costs. To this end, this paper proposes a LEO satellite IoT constellation design algorithm with the goal of minimizing the total cost while satisfying quality of service (QoS) requirements in terms of coverage ratio and communication quality. Simulation results validate the efficiency of the proposed algorithm in LEO satellite IoT constellation.
