A Wireless Sensor Node Based Efficient Parking Slot Availability Detection System For Smart Cities

In the past ten years, advancement in technology has been a great importance for Smart Cities. The concept of smart parking system is revolutionizing in the smart cities. Internet of Things (IoT) provides an efficient smart parking system in smart cities. The current smart cities have limited parking slots which are not managed effectively. Due to unavailability of accurate information about parking lots, drivers have to face inconvenience and traffic congestion on roads. This factor motivated us to develop an effective parking slot availability detection system for smart cities. In this paper, we proposed a solution that utilizes the wireless sensor node (combination of Ultrasonic Sensor and Wi-Fi technology) to detect the movement of the car at the entry and exit level of parking lot. The information is collected dynamically and updated in our cloud database. A mobile application is also developed for checking the parking slot availability in a nearby location. The real-time information of the slot vacancy can be dynamically sent through an android mobile application. The proposed solution deploys a wireless sensor node on the site for providing accurate information for driver's requests. Finally, the working functionality of our proposed solution is developed as a prototype and illustrated as a working model.
