The activities e.g., monitoring and communication by IoT can play an important role to designanIntelligent Transportation System (ITS). In this paper, we assess the suitability ofIoT enabled wireless technology to be used forITS. We performed some comparative study to find the best wireless technology that provides reliability, low cost, less power consumption and less data latency for next generation ITS.This technology will reduce energy consumption of the deployed IoT devices as well as ensure safety, efficiency and convenient for transportation systems.

INTRODUCTION Internet of Things (IoT) connects physical objects by a communication system (e.g., wireless sensor network (WSN)) that facilitates to acquire and share information; monitor, track and control the Things (some objects e.g., actuators, motors);[1, 2]. IoTcan be divided into a sense layer, a service layer, a network layer, and an application layer. The sense layer can sense, collect information, and the network layer permits the interaction among the different items using Internet technology, whereas the service layer provides solutions to the application or to the other end users for further intelligent processing[3]. IoT can add a new area to Intelligent Transportation Systems (ITS)due to a growing demand of efficient, low-power consumption and low cost. There are various challenges and issues in implementing this emerging solution toward ITS, e.g., real-time traffic management system, smooth and seamless connectivity, exact vehicle location forecast, security and privacy, interoperability, proper communications, associated with IoT that need to be addressed[4, 5].Fig. 1 shows the general architecture of IoT enabled Intelligent Transportation System paradigm.
