Secure storage of dynamic node information in smart parking using local blockchain

One of the challenges drivers face in today’s fast-paced urban world is the ability to access parking spaces quickly. The increase in the number of vehicles in cities, especially in urban areas, as well as the growth of network services in smart cities, has created the need to provide easy-to-use smart parking networks. However, the most critical challenge in building such a network is the secure storage of customer and service provider information. Using blockchain to store data securely requires powerful computing resources and high energy consumption. In this research, combining existing ideas in the field of smart parking and blockchain, a solution will be proposed to use blockchain in dynamic nodes with poor computing resources, such as sensors used in smart parking. As one of the layers introduced in smart parking, we simulated the proposed algorithm in a wireless sensor network (WSN). In light of the findings of previous studies demonstrating the efficacy of Zigbee technology as a mesh topology in WSNs with low-cost infrastructure and resource requirements and our simulation results, we employed this technology to evaluate its performance in our proposed smart parking application. On the other hand, functions created with the Solidity language can use online payment services on such a secure network.
