Parking is a big issue in cities. A smart parking scheme can lessen the traffic congestion and hassle for locating a free parking space. Internet of Things (IoT), unmanned aerial vehicle (UAV), and mobile edge computing (MEC) are emerging technologies that can provide great benefits in terms of managing parking space. However, communication in these technologies surrounds with threats like man-in-the-middle attacks, replay attacks, illegal data tampering, etc. A blockchain-enabled smart parking scheme is proposed in which parking information are collected via UAV and stored in MEC server securely using blockchain. An experimental setup is discussed in the paper. The experimental result manifests that proposed scheme provides better support than the MEC server in terms of energy consumption.
