  2. Literature review

    B. G. Mohammed and associates (2023) [1], This article's goal is to use the SIM7600E GSM and GNSS HAT (uplink hardware) module to track body temperature (DS18B20), heart rate, and SPO2 (MAX30100) and to get the affected person's condition as needed. A Raspberry Pi 4B microcontroller is used to get statistics from measurement instruments. Through the network, sensor data is routed to cloud storage. The suggested equipment utilize the newest IoT microcontroller and device models, which is assumed to have an impact on the system's overall accuracy and speed. GUI cross-platform mobile applications are become more popular and give patients and physicians real-time analysis. By enabling real-time patient health monitoring, the technology helps physicians promptly choose the right tests at the right moment.

    Yadav and colleagues (2023) [2], We suggest an Internet of Things-based healthcare system in this essay. Modernize this device to enable authorized staff to access and keep an eye on patients in outlying locations. In a similar vein, a large number of patients are admitted to state hospitals and clinics, a large number of patients require emergency care, physicians are impacted by services and treatments while on sick leave, and so on.

    Hridhya,Assam Pradesh (2023) [3], According to this article, the Internet of Things (IoT) is a

    technology that allows things to be remotely monitored or controlled by means of an internet connection. Statistics are routinely gathered from networked devices, examined, and utilized to start necessary activities. Sensors and gateways, which enable user communication and data access, are the foundation of the Internet of Things idea. We therefore need a cutting-edge model that can automate this. The system is a fantastic resource forhealth of patient, monitoring vital signs including body temperature, blood oxygen level, and heart rate via a web server. The humidity and temperature of the room are also tracked. Using the Android app that is loaded on their cellphones, caregivers can access information regarding the patient's condition.

    B. Hemalatha and associates (2022) [4], This article addresses safety guidelines that commercial sensors can apply, enabling patients to be watched over without going to the doctor. In this crucial circumstance, doctors must frequently update their patients' vital signs, such as blood pressure, heart rate, and body temperature. In this case, clinicians can update patient records more efficiently by using IoT-based devices.

    In recent years, coronary heart disease has become a major concern and has claimed countless lives. several health issues. As a result, heart conditions require extremely cautious treatment. If ECG signals are analyzed or tracked in a timely manner, this illness can be avoided. This is it: Use an Arduino with an ECG diagram and an AD8232 ECG sensor to measure heart rate. This architecture makes use of the cloud computing concept and makes use of the Arduino Uno card as a microcontroller. In this setup, the AD8232 ECG sensor is connected to the Uno, and the ECG is analyzed using a virtual project or programming IDE.

    Agnihotri S. and associates (2021) [5], We discovered that there are various forms of communication, including heterogeneous hardware (such as Arduino, Raspberry Pi, and others), technology that can be used effectively (such as smart watches, fitness trackers, smart glasses, and smart clothes), and heterogeneous communication technology (such as Bluetooth, Wi-Fi, and mobile phones).

This enhances access to care, lowers medical expenses, improves patient safety, and increases the effectiveness of medical procedures. Here, the adoption of practices that facilitate the use of technology, healthcare services, and apps to treat a variety of health issues is what advances the efficacy of HIoT. Expected circumstances and potential issues with HIoT systems are also covered. In conclusion, the observations of today offer precise information on the particular application of HIoT,

    assisting future researchers who are eager to work and be successful in this sector in making business-oriented entry.

    Sahoo, P.K. and associates (2016) [7], Future health projections and the assessment of the treatment described here are still in the informational stage. cloud-based analytics for large data. The platform is a useful tool for managing healthcare data analysis, both organized and unstructured. This article describes how to do a correlational analysis and verify that the data that has been gathered is accurate. In the end, a stochastic prediction was created using the total of the patients' present health statuses to predict the patients' future health. The suggested system's total performance evaluation comes from a large-scale experiment that reduces time measurement by controlling 90% of CPU and bandwidth utilization and achieving roughly 98% forecast accuracy in a cloud context.

    J. Gómez and colleagues (2016) [8], According to this article,The economy is greatly impacted by the active use of smartphones and other smart devices in the healthcare industry.

The system will learn from the user and apply inference and reasoning to understand the person's habits and preferences. This system is designed to use data from pervasive and intelligent sensors that respond and monitor the state of the environment and the activities of its occupants, thus the aim to use IoT to ensure the correct implementation of such a system. This project is still in its infant stages but illustrates the potential growth of IoT in the context of AI and machine learning for elderly healthcare.

      The ability of a computer or program to think and learn is known as AI. The ultimate goal of the research that goes into AI is to create technology that will allow a computer to function and learn as a human does. A sort of artificial intelligence known as machine learning gives computers the capacity to learn without explicit programming. This being said, AI and machine learning are already making revolutionary changes to healthcare. In terms of IoT, machine learning algorithms

      are being used to identify patterns in data that has been collected from devices worn by patients. These patterns can then be used to make a diagnosis and recommend a course of treatment.

Said in another way, make a system which will tackle a particular medical problem equally or better than a human expert. Such systems work in a way similar to solving an optimization problem. They observe the current state of a complex system (in the case of the diagnostic procedure, this system is a patient with a certain medical condition), store the data, and possibly later modify the system and observe the outcome. By finding the best action for modification of the system in all possible states, so-called policy, the system can determine the best diagnosis and treatment for the patient. In this approach, we can use the latest technology for AI and ML (namely neural networks and deep learning), which has provided significant breakthroughs in recent years. Considerable work is also done on the development of simulation models for various conditions and diseases. By coupling these with intelligent decision support systems, it may be possible to optimize the treatment for a patient or even apply techniques of inverse modeling to estimate the best possible action for a modification of some conditions, given a desirable outcome.

      2. Predictive analytics for personalized treatment

        Predictive analytics plays a vital role inreshaping personalized treatment in healthcare. By drawing on vast amounts of patient data, including medical history, hereditary information, lifestyle factors, and treatment responses, predictive analytics can generate insights that enable healthcare providers to tailor treatments to individual patients' needs.This data isexamined by machine learning algorithms, which then find trends, forecast the course of the condition, and suggest tailored interventions. This strategy not only enhances treatment results but also reduces side effects and maximizes the use of resources in healthcare systems.Furthermore, predictive analytics empowers healthcare professionals with predictive models that aid in decision-making, leading to more precise diagnoses, proactive interventions, and ultimately, improved patient satisfaction and well-being.
