Abstract
Internet of things (IoT) is the extension network of the Internet. Internet-enabled objects have the ability to sense and communicate with other objects or humans. Enormous components are used to build the IoT network. IoT begins with the connectivity since IoT is extensively diverse. It is certainly obscure to find a single size fits to all the types of communication. Various solutions have their strengths and weaknesses in different network criteria to best suit different IoT applications. IoT is available in various forms. One of the different types of IoT available for deployment is narrowband IoT (NB-IoT). NB-IoT is famous due to its attractive features of low power wide area (LPWA). Though the challenges such as security, latency, interoperability, policymaking, and resiliency exist for all types of IoT network, it can be improved with careful architectural design. In this chapter, the authors highlight the fundamentals involved in building the network of internet-enabled devices. It describes types of IoT networks, different computing mechanisms in IoT, basic architecture underlying the development, applications in the expansive domain, and finally, the insight of the challenges in IoT.
