  Internet of things (IoT) has been proven to be a ubiquitous technology for
several existing and new applications. It can provide both accuracy and
sustainability in the emerging services and applications. IoT has several
advantages and it can provide different levels of coverage in different
geographical locations and contexts. There are several applications in which
the wide coverage, low power and reliability of the communication have very
high priorities. Conglomeration of IoT and satellite networks can make it very
attractive for these applications. In this article, we present the general
features, motivation and deployment issues of satellite based IoT networks. We
present the applications where these satellite based IoT networks can play
important roles. We also present the hybridization of narrowband IoT and
satellite networks which can provide a long term sustainable network solution
for several applications.
