Satellite Visibility Prediction for Constrained Devices in Direct-to-Satellite IoT Systems
IEEE Sensors JournalThe Internet of Things (IoT) enables the transport of small amounts of data from/to constrained devices such as sensors and actuators. When these devices are located in remote areas without terrestrial network coverage, the Direct-to-Satellite IoT (DtS-IoT) systems become cost-effective solutions.

Packet Collision Probability of Direct-to-Satellite IoT Systems
IEEE Internet of Things JournalWe investigate the packet collision probability among uncoordinated devices, in the uplink of Direct-to-Satellite Internet of Things (DtS-IoT). Both the satellite spot shape and its motion along its orbital path are considered in the analysis. We analyze the probability of no uplink collision under two DtS-IoT settings: 1) unconfirmed ALOHA over a ...

Sensor Deployment and Link Analysis in Satellite IoT Systems for Wildfire Detection
GLOBECOM 2022 - 2022 IEEE Global Communications Conference, 2022 Climate change has been identified as one of the most critical threats to human civilization and sustainability. Wildfires, which produce huge amounts of carbon emission, are both drivers and results of climate change. An early and timely wildfire detection system can constrain fires to short and small ones and yield significant carbon reduction.
