Age-Optimal HARQ Design for Freshness-Critical Satellite-IoT Systems
IEEE Internet of Things Journal, 2020In this article, we consider the satellite Internet of Things (IoT) system, in which the IoT device observes physical processes and transmits the status updates to the monitor node over an error-prone channel with nontrivial propagation delay. The freshness of status updates is characterized by Age of Information (AoI), a novel metric that is defined ...

IoT Gateway Association and Data Scheduling for Delay Optimization in LEO Satellite Systems
2020 IEEE/CIC International Conference on Communications in China (ICCC), 2020As a critical supplementary to terrestrial communication systems, low-earth-orbit (LEO) satellite communication systems have been gaining growing attention in recent years. In this paper, we consider an LEO system where a number of Internet of things (IoT) gateways need to send their collected data to LEO satellites.

Distributed Probability Random Access Scheme in Satellite IoT System
2018 IEEE 4th International Conference on Computer and Communications (ICCC), 2018Satellite Internet of Things (IoT) network where IoT terminals randomly access the wireless channel and transmit packets to satellites develops rapidly in recent years. Although great progress on satellite multiple access has been made in Random Access (RA) algorithms, packets loss and low throughput present an obstacle for satellite IoT network.
