has not affected all countries equally: developing countries have been more disadvantaged by the pandemic. Regarding global development, the COVID-19 pandemic has forced a step back in the path to attaining the Sustainable Development Goals (SDGs). The SDGs most negatively affected by the pandemic are identified here. Then using the SDGs as a reference, this research explores the new challenges faced by developing countries and the impact of the Internet of Things (IoT) after COVID-19's emergence. Successful Internet of Things for Development (IoT4D) projects, in relation to the SDGs, are highlighted. Challenges of the IoT4D in the wake of the COVID-19 pandemic have been identified and the new social and technical challenges emerged as consequence of the pandemic have been studied. IoT solutions carried out in developing countries during the pandemic have been identified and reviewed. Finally, this work concludes that the future of IoT4D in the wake of the COVID-19 should focus on the use of low-cost IoT on the most affected SDGs by the pandemic: education, health, and work. After an exhaustive study, the Intelligent Internet of Things (IIoT) has been identified as a key actor in the pandemic wake, with a leading role in the health sector. The proposed approach included an exhaustive study of the new role of the Internet of Things for Development for achieving the SDGs in our forever changed world.INDEX TERMS Internet of things; artificial intelligence; Internet of things for development; sustainable development goals; COVID-19; IoT4D; developing countries.
