CPS in block chain smart city application based on distributed ledger based decentralized technique

Abstract

This article offers a brief overview about cyber-physical systems enabled by blockchain (CPS). Dissects various blockchain-enabled CPS reported on the operations and blockchain characteristics used in the literature. Base of its time sensitiveness and throughput requirements, we identify and categories key common CPS operations that can be activated by blockchain. We also develop blockchain features and categories in terms of diverse levels of benefits to CPS like security, privacy, immutability, tolerance of defects, interoperability's, data origin, atomicity, automation, information/service sharing and trust. This paper provides an overview of the concept of intelligent cities as well as emerging technologies and a quick overview of cyber-physical systems. It then discusses CPS' potential role in the development of intelligent city apps and some real-life examples of CPS adaptation for city smart projects. A decentralized database based on distributed ledgers has been introduced. Distributed ledgers are a distributed database with a network connection node. These nodes include ledgers that list transactions with timestamps.
