Research on IRSA access technology for space-based IoT

Abstract

With the development of space-based Internet of Things (IoT), random multiple-access technology has become a hot topic. This paper examines the impact of the number of time slots per frame and the number of iterations on the performance of Irregular Repetition Slotted ALOHA (IRSA) access technology from the perspective of system throughput rates. Then the concept of packet generation probability is proposed and its relationship with the number of users is investigated. It provides a reference for the communication system of space-based IoT.
