Abstract The aim of this research work is to propose ticket based smart car/vehicle parking system using Internet of Things (IoT) along with mobile application in vehicular network. Smart Parking mobile app helps in finding a slot to park the vehicle using live information that is obtained from the sensors placed in the parking area. Initially the number of available parking slot in the parking area is calculated and the parking tickets are generated for all the parking slots. To avoid the occupancy of already booked parking slot by a random person, ticket based parking slot allocation is proposed here. Detection of available parking slot is done by using communicative method by considering the total number of parking spaces, number of vehicles parked already, number of cars waiting to park, number of vehicles that about to leave. All information’s like slot allocation, slot direction and billing are collected by the sensors that are placed in each parking row and sent as a message to users mobile phones.
