**4. Prototype for dynamic HUB selection**

The Dynamic Hub selection outraced the results of the traditional hub by implementing it in LabVIEW through Fuzzy based system. This is now tested by a prototype developed on the testbed to have a look at the changes in HUB selection concerning the real-time body measurements. As technology has a great impact on health and mobile phones these days become a valuable asset for a normal man. On this point, we connected an app that stores information about the vitals from the human body. Here, an embedded C is evolved to change the HUB dynamically and is provided in a mobile app where the HUB selection is shown in the app. The embedded communication devices used are for the programming of the network as they are designed for a special purpose rather than the general tasks of computers. These are inbuilt with memory storage, a processor, and some peripherals. It can assist using C, ALP, and VB, etc. It also stores the information about the vitals collected for future purposes. As discussed above, the root cause for tissue damage is the temperature rise, working for a longer period in the network. In this prototype, a traditional hub is changed according to the vitals collected from the patient. Based on the functionality and requirement, the embedded system is deployed in our mobiles and so as in this work. The different sensors used in the prototype are described below in **Figure 9**, where the network is placed on the surface of the body.

ESP-32 is a 2.4 GHz microcontroller with both Wi-Fi and Bluetooth combination chip designed for better power and good reliability with a wide range of applications, which consists of an I2 C bus interface, recovery memory, ROM, SRAM, temperature sensor, touch sensor, clock generator, a serial peripheral interface, DAC, ADC, UART (Universal Asynchronous Receiver Transmitter), PWM, Wi-Fi, and Bluetooth peripherals along with radio receiver and transmitter.10 capacitive sensing GPIOs present in the microcontroller are useful for our project as we use a touch sensor for monitoring the heart rate through the illusion of light by finger and the other three sensors are deployed.

The deployment materials used here are a Power supply, Temperature sensor, Heartbeat sensor, Blood pressure monitoring device. The power supply is used to convert high voltage to a low voltage supply, which consists of a transformer,

regulator, filter, and rectifier. The temperature sensor, LM 35 is used here to convert the temperature into electrical signals. Yet, it does not require any calibration and best suitable for our work. Having said that, this is considered a low power supply and low self-heat not more than 0.10 c in still air, most widely used in remote applications. The different male and female connection wires are used for creating a system.
