GreenGuard: Emission Monitoring System over cloud for Metro city

The objective of this paper is to monitor air pollution on roads and track a vehicle which causes pollution. In order to solve this problem, many countries and regions have already presented a series of emissions standards, meanwhile some methods have been developed, including update motor engine or improving the quality of the gasoline. However, these actions have not brought about striking effect as we expect. In this system, Radio frequency identification (RFID) technology as a low-cost and mature wireless communication method is adopted to collect and transmit emissions information of vehicles and Internet of Things (IoT) concept is proposed. Moreover, The RFID devices need to be installed on the traffic lights so that reliable reading of emissions signals from a vehicle can be interrogated when the vehicles stop in front of the red light. By applying the system, it is possible to smoothly realize a green traffic network.
