In Section VI, an overview of big data analytics techniques and tools is provided. In Section V, we present the different big data processing tools from cloud data processing and multi-cloud processing to big data clustering techniques, NoSQL and fog computing that help facilitate the analysis of large volume of data. Then, in Section IV, we discuss about big data caching and routing for better CPS data management. Section III describes the different sources, generations, and collections of big data for CPS, mainly context-aware computing, communications, and social computing, while Section IX presents different CPS-related big data applications. Section II compares this paper with other related surveys in literature. The sections of this paper are organized as follows. The relevances of big data era and CPS actually are also highly relevant to global sustainability development goals recently discussed in. The characteristics of big data was well summarized in the Introduction section of. That is why big data are referred to as вЂњ the 21 st century new oilвЂќ. That is why, cloud computing techniques along with machine learning tools, data mining, artificial intelligence, and fog computing can help the sensed data to be easily stored, processed, and analyzed to uncover hidden patterns, unknown correlations and other useful information. However, this enormous amount of data is so large in size and complex in real-time that it exceeds the processing capacities of conventional systems. CPS have resulted in a tsunami of new information, also known as big data, which can help boost revenues of many businesses, by identifying customer needs and providing them with superior services. For instance, the standardization activities of IoT are being led by the industry (AllSeen Alliance, Open Interconnect Consortium, Industrial Interconnect Consortium) and IEEE P2413 project on standards specifications of IoT architectural framework

The global expansion of interconnected CPS is facilitated by standardization efforts. This means that IoT acts as a connection bridge to network different cyber-physical things. Internet of Things (IoT), on the other hand, allows different CPS to be connected together for information transfer. A CPS mainly consists of physical components and a cyber twin interconnected together, where a cyber twin is a simulation model representative of the physical things such as a computer program. This has allowed the rapid development of myriad of applications in health-care, public safety, environmental management, vehicular networks, industrial automation, and so on. Indeed, it is expected that over 50 billion sensors will be connected to the Internet, with an average of 6.58 devices per person by 2020. The growing number of вЂњthingsвЂќ, such as embedded devices, sensors, radio-frequency identification (RFID), and actuators have revolutionized the world through their integrated communication and tight interactions to create pervasive and global cyber-physical systems (CPS). We also discuss big data meeting greenД¬hallenges in the contexts of CPS. Provide an overview of the different security solutions proposed for CPS bigДata storage, access and analytics. Unauthorized intrusion, which become a challenge with the enormous amount ofДata that is continuously being generated in the network. Require cybersecurity to protect them against malicious attacks and To provide a panoramic summary of different CPS aspects. This is the first panoramic survey on big data for CPS, where our objective is Storage, access, processing and analysis. Present the CPS taxonomy via providing a broad overview of data collection, To outstandingly increase the growth rate of raw sensed data. Sensors deployments that are anticipated in the near future. Smartphones, tablets and video streaming, along with the significant growth of The information and communication technology (ICT) sector is experiencingДЄ significant growth in data traffic, driven by the widespread usage of Monitoring, mobile-health systems, intelligent transportation systems and so Services and applications in a variety of sectors such as environmental (CPS), which are foreseen to revolutionize our world via creating new The world is witnessing an unprecedented growth of cyber-physical systems
