Abstract The advent of new wireless and Internet of Things (IoT) technology has increased the dependency on the cellular base stations (BS). The rapid growth in IoT and wireless devices impinges many challenges on cellular services providers and manufacturers. The Centralized Radio Access Network is an energy and cost‐efficient solution for the next‐generation BS architecture. In this article, we have proposed a centralized‐IoT (C‐IoT) architecture based on centralized BS (C‐BS). We evaluated different base station technologies and compared the C‐BS with the traditional distributed BS (D‐BS) architecture for power consumption. A mathematical model for power consumption for both types of BS is proposed. We have analyzed the impact of variation in traffic load on power consumption for both types of BS architecture. The simulation result shows that C‐BS architecture has the potential to save around 40% to 50% energy compared with D‐BS architecture.
