## 5 Experimental Results & Analysis

This section presents the experimental analysis and the discussion of the experimental results of our Digital Twin scenario. To verify the better use of our proposal and to test its performance, we made a variety of measurements so that we could assess our level of effort. With the following experiments, we can show the importance of the Digital Twin scenario for such systems that use large-scale data streamed through the network. Figure 5 illustrates the data produced and transmitted through the procedure using the proposed algorithm and a conventional algorithm. The blue line represents the results of the conventional algorithm and the green line represents the results of the proposed algorithm. As we can observe, our proposal could be more efficient because it could produce and transmit more data sets at the same time compared with the conventional algorithm. The impact of our proposed model depicts the efficiency of the usage of a Cloud Management System operated over a Digital Twin scenario, using real-time large-scale data produced from the connected IoT system. The Digital Twins concept is most frequently used to better \"predict\" functionality through a virtual model designed to accurately reflect a physical object. Through such a system, useful information could be extracted about its reliability and its usage, as well as the degree of improvement of the existing system/object [73; 76]. Figure 6 describes the better Energy Efficiency offered by the Digital Twin scenario that implements our proposal. As we can see, our suggested scenario consumes less energy over time than the other examined frameworks. A more sustainable and ecologically friendly framework can be provided, as well as a better solution for energy use. The need of using a more environmentally friendly system, due to less energy consumption, is a major goal that we try to overcome and achieve. Thus, Energy Efficiency is a major goal of our system implementation based on modern needs. Additionally, with the use of the Digital Twin scenario, we could achieve a more economical system by using less physical hardware. Moreover, through the experiments, we can prove that the successfully created a system uses less energy than other related systems. Additionally, with less energy consumption, we could achieve a more reliable and secure system for monitoring. Figures 7-10 demonstrate four different experimental scenarios that consider the better Energy Efficiency offered by the Digital Twin scenario that implements our proposal of different measurements in time. Through these scenarios, we can observe that our proposal

To benefit from features of the IoT and improve the usage of video monitoring and technology of the Internet of Things, these have been combined concerning the use of the monitoring and the future requirements for this technology. The major IoT features shown and presented in this research were based on the findings of our literature review research. These features led us to try to find out a better secure and more efficient novel system that could be established and operated on buildings where more IoT big data is produced, transmitted, and managed.
