A Study & Proposed Architecture for Large Scale IoT Networks in the space of Public Transportation

In today's modern society, Internet of Things has proved a substantial role in our lives. From medical applications, industries, smart homes to surveillance base systems, IoT has found itself a place in almost every pace of life. Transportation is one such area where IoTs play an important role. In the concept of smart cities, various IoT based Transportation projects have been proposed and developed across the globe. These projects have been theorized to cover major portions of an efficient and intelligent smart city. Although a major leap, these projects still have various gaps with respect to how various systems are designed and handled throughout the entire Traffic management system. Thus, the main aim of this paper is to propose and discuss the various prospects of a comprehensive Transportation system. A top-bottom system is presented, in which different views are presented IoTs can be implemented in public transportation in order to properly collect, manage and process data with the help of Software Defined Networks (SDN) and Network Function Virtualization (NFV). The proposed architecture is divided into three main parts; where the function, individual and collective working of each part is discussed, keeping in view the gaps of previous projects. Furthermore, several latest works in literature have also been incorporated to fully explain the functionality of the Transportation architecture.
