Over the last few decades, emerging technologies (such as Big Data Analytics, Cloud Computing, Software Defined Networks, etc.) necessitated a paradigm shift from a traditional centralized communication infrastructure to decentralized one. In such a setup, billions of Internetenabled devices are interconnected in an environment popularly known as Internet-of-Things (IoT). the number of such interconnections reduces the computational overhead and complexity by distributing the workload among geo-located nodes. However, it may generate various types of security threats and challenges due to the usage of an open channel i. e., the Internet. The security threats such as denial-of-service, eavesdropping, man-in-the-middle, etc. are dependent on authorization, authentication, and accountability (AAA) methods used in the IoT environment. Extensible authentication protocol (EAP) is one of the popular authentication protocols used to mitigate these attacks in an IoT environment. Also, the transport layer security (TLS) and secure socket layer (SSL) are necessary protocols used along EAP for establishing a secure communication channel between various smart devices in this environment. However, the aforementioned schemes are built using a centralized architecture or heavily rely on central decision-making authority, raising issues of a single point of failure and long delay. From the above discussion, it is clear that security and privacy are the major concerns for the successful implementation of any solution in such an environment. Moreover, the evolution of technologies as mentioned above make it difficult to capitalize the existing centralized security mechanism to handle the diverse requirements of geo-dispersed ecosystems (edge computing, smart grid, intelligent transportation systems, etc.) To overcome these issues, blockchain technology is being used that provides identity privacy and transaction security using a decentralized and dependable architecture. It is a peer-

The available materials demonstrate only a small portion of Electromagnetic properties that are theoretically discussed and studied. Initially, J. C. Bose realised and emphasised the possibility of artificial material by arranging twisted structures such materials with 'meta' properties were given the term 'Metamaterial'. The metamaterial are engineered materials which are developed artificially. The artificially design metamaterial provides negative permeability and negative permittivity which result in found its usage in many engineering applications one of such application is metamaterial absorber. In 2004, researcher Smith and his team realised the significance of Metamaterial in various applications. Soon after, researcher Landy and his group provided the information about metamaterial based microwave absorber, the work mentioned was notified with special term 'Prefect metamaterial absorber'. The work formed a base on which latter researchers and scientists experimentally demonstrated and applied Absorption principle in various reported work. When an electromagnetic wave is incident at the boundary interface of two regions then some part of the wave is reflected back in first region, some part gets transmitted in the second region and the remaining part gets absorbed provided no scattering and/or diffraction is occurred. The waves which get absorbed in the material if effective properties like permittivity and permeability are tailored to needs, resulting the absorption of the wave at a particular band. The optimization of physical parameters of metallic layer, thickness of dielectric substrate etc. led to coupling of Electric and magnetic fields to specific input impedance and this input impedance can further be matched to free space impedance for maximum absorption. This complete absorption of electromagnetic wave is realised by minimisation of reflection coefficient. This properties can be utilized for various strategic and important engineering applications

The Republic of India, which has the second-largest population in the world, has challenges in meeting its rising energy demands by reducing fossil fuels. Also, the energy produced by fossil fuels contributes to global warming as the energy sector is explicitly responsible for generating harmful substances during the production, distribution, and consumption of energy. Without posing any environmental risks, the Sun, a limitless energy source, can be used as an alternative to meet this rising need. Further, the advancement of technology in chemistry, material science, and solid-state physics improves the efficiency of photovoltaic (PV) modules, has resulted in various topologies with different performance characteristics, and added sun-fuelled plants to a portfolio of the electricity market. Despite their many advantages and relative popularity as a renewable energy source, Even the greatest solar panels eventually lose their effectiveness. Inspections are necessary to maintain cell performance levels and minimize financial losses since solar cells are susceptible to damage from weather- related incidents, temperature changes, and UV exposure over time. How can real-time panel inspection be done in a way that is both economical and quick? This research work exploits the possibility of real-time estimation of solar power in PV systems. A new method was brought to light: Utilizing historical weather data, the Clustering-based Computation Rate (CCDR) calculates performance ratios and degradation rates. This method also allows for off-site inspection. Most meth- ods on the market base do their calculations via on-site physical assessment of PV installations. These methods are not preferred for real-time degradation investigation because it is time-consuming, expensive, and labor-intensive. The suggested model provides a real-time estimation of the performance ratio. The degradation effect in terms of performance ratio is incorporated in estimation results. The degradati
