###### Abstract  
The Internet of Things (IoT) was introduced as a recently developed technology in the telecommunications field. It is a network made up of real-world objects, things, and gadgets that are enabled by sensors and software that can communicate data with one another. Systems for monitoring gather, exchange, and process video and image data captured by sensors and cameras across a network. Furthermore, the novel concept of Digital Twin offers new opportunities so that new proposed systems can work virtually, but without differing in operation from a \"real\" system. This paper is a meticulous survey of the IoT and monitoring systems to illustrate how their combination will improve certain types of the Monitoring systems of Healthcare-IoT in the Cloud. To achieve this goal, we discuss the characteristics of the IoT that improve the use of the types of monitoring systems over a Multimedia Transmission System in the Cloud. The paper also discusses some technical challenges of Multimedia in IoT, based on Healthcare data. Finally, it shows how the Mobile Cloud Computing (MCC) technology, settled as base technology, enhances the functionality of the IoT and has an impact on various types of monitoring technology, and also it proposes an algorithm approach to transmitting and processing video/image data through a Cloud-based Monitoring system. To gather pertinent data about the validity of our proposal in a more safe and useful way, we have implemented our proposal in a Digital Twin scenario of a Smart Healthcare system. The operation of the suggested scenario as a Digital Twin scenario offers a more sustainable and energy-efficient system and experimental findings ultimately demonstrate that the proposed system is more reliable and secure. Experimental results show 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. Through these scenarios, we can observe that our proposal remains the best choice regardless of the time difference or energy load.

Networks for communications may be utilized by monitoring technology. Considering that they transmit videos or data generated by monitoring equipment, a device must be connected to the network for the information to be transferred. Using a method known as multi-alteration, the geographic location of a mobile device can be more easily determined, even when the phone is in standby mode. In other words, tracing an inactive device can be performed by comparing the lengths of time required for a signal to go from one mobile phone to any nearby cell tower [1; 2; 3; 5; 9]. A recent development in communications technology is called the Internet of Things (IoT). The IoT is \"the system of physical objects and devices with sensors and network connectivity that enables these objects to collect and share data\" [1; 2; 3; 5; 6; 10]. The next big development is IoT technology, which will fundamentally alter how businesses operate. In the approaching years, it is anticipated that there will be a sizable and quickly expanding number of connected devices, installed sites, and operations that would carry out [3; 5]. Also, the Internet of Medical Things (IoMT) is a new era of this technology representing Healthcare-IoT systems and data [6; 10; 11; 12]. Additionally, in places such as offices, and homes, an array of sensors may monitor utility networks, and provide early prior notice of falling electricity, water leakage, and overload of the electricity network. The information gathered will be used to improve performance, pinpoint particular needs, and establish particular requirements.
