Role of non-terrestrial networks in achieving sustainability in IoT devices

This chapter addresses how Non-Terrestrial Networks (NTNs) can revolutionize the Internet of Things (IoT) sustainability. With the rapid growth of the IoT, NTNs are crucial to reduce dependence on terrestrial infrastructure, optimize energy consumption, and enable connectivity in remote and underserved regions. Key discussions include integrating NTNs for wide coverage, leveraging energy-efficient technologies, and overcoming sustainability challenges such as carbon emissions and space debris. It covers different case studies that highlight how NTNs help precision in agriculture, disaster management, and environmental monitoring. Practical solutions and future research directions give force to the potential role of NTNs in a greener IoT ecosystem. Recommendations about policy practices on sustainability and international cooperation also take into consideration NTNs' potential roles for a connected and sustainable future.
