Abstract—The Internet of Things (IoT) is often embedded as a crucial part of many smart systems, especially in car park recommendation systems. Such recommendations require the knowledge of the current location of the car driver through a mobile application, yet existing mobile sensors such as GPS and Barometer sensor are not significantly qualified or stabilized to deliver a current location. Therefore, this research proposes using an installed IoT location based service, named Beacon, to act as a proximity sensor to transmit current car locations to recommend nearby parking spaces to the driver via a mobile application. The proposed system is explained in detail and implemented to test its accuracy. In the experiment, the accuracy of nearby parking space recommendations was assessed and compared with previous studies.
