Smart city trends have been growing dramatically in today’s scenario. So, to fulfil the needs of smart city trends many hardware and software are being developed. This paper discusses the current status of architectural designs, hardware and software designs in smart mobility. Smart mobility is also one of the classes that fall under Smart city infrastructure. So, we are going to discuss different IoT-based architectures for Smart Mobility. There are many Internet of Things (IoT) based architectures that are being made for Smart mobility. But, each architecture has some flaws and are only supporting a small part of the smart mobility trend. So, in this paper different architectures are reviewed and compared for the pros and cons. By analyzing the information gathered from different smart mobility services we propose an architecture which is feasible and with the pros of most of the previous architectures. Also, this architecture is built on a blockchain network so the network is secure and private which is one of the greeted problems faced in the IoT ecosystem.
