2.RELATED WORKAsmentioned in previous section, the IoT takes important place ine-Health and medical care by using different sensing devices andwireless sensor networks (WSNs). Much research on this topic has been done, which can be further categorized and enumerated.
A.Architecture: Punit Gupta, Deepika Agrawal, Jasmeet Chhabra, Pulkit Kumar Dhir, have proposed a model which presents the design and implementation of an “IoT based Smart Healh Care Kit” for emergency medical services which can be demonstrate collection, integration of IoT data flexibility which provide support to services like intensive care unit(ICU). They have used a INTEL GALILEO second Generation Development Board. Using this system the time for patients and doctors are saved. Doctors can help in emergency services as much as possible. Galileo Board collects data from all the sensors connected to patient and the data is uploaded to an webpage through ethenet for temperature calibration.
They had used LM35 sensor and Xampp based data served used for patents timely record. Abhilasha Ingole, Shrikant Ambatkar, Sandeep Kakde have proposed a paper which describes “Implementation of Healthcare monitoring System using Raspberry Pi”. This system is designed to read the body temperature and heartbeat of patients at runtime.
It is focused on collecting the physical parameter and then that information is made available for multiple users. They have used Raspberry Pi B+ model which can be interacted with different parameters measuring unit. In this paper, basic health parameter are considered and monitored.
The operating temperature range of DS18B20 is -55oC to +125oC and it provides the accuracy about +0.5oC over the range of -10oC to +85oC. Each DS18B20 is provided with a unique 64-bit serial code. Augustus E. Ibhaze, MNSE, Francis E. Idachaba, Ezimah C. Eleanor have proposed a system “E-health Monitoring System For the Aged”.
The system monitors the heartbeat and temperature of patients simultaneously with the pulse sensors and the temperature sensors by populating a centralized database with its reading of defined intervals or have risen beyond preset threshold, the device make use of the GSM/GPRS/GPS shield to send the readings and location coordinates to the patient’s doctor guardian to quickly track and examined/diagnose the patient’s condition. By using Arduino microcontroller sensors attached to the figure of the patient for measuring temperature and heart rate. Also it is designed to recognize the location of the patients. This device takes gv powered battery. Prosanta Gope and Tzonelih Hwang proposed a model,” BSN Care: A Secure IoT Based Modern Health Care System Using Body Sensor Network”. This paper presents a body sensors technology. It consist of wearable body sensors like EMG(Electromyography), ECG (Electrocardiagram), blood pressure etc. It uses wireless communication using 3G/GPRS/CDMA.
To achieve security requirements, they proposed a lightweight anonymous authenticated protocol and to get data security requirements. Used OCB i.e offset codebook authenticated encryption mode. Kaleem Ullah, Munam Ali Shah, This presents the model named as ‘k-Healthcare’ makes use of four layers, sensor layer, network layer, internet layer and service layer. There are different sensor used like RTX-4100, Arduino, Raspberry Pi, pulse oximetry and smart phone sensors. Communication between layers is done through IEEE 802.
A.Divya, K.Keerthana, N.Kiruthikanjali, G.
Nandhini and G.Yuvaraj, This paper represent ” Secured Smart Healthcare Monitoring System based on IOT”. In this system we used PIC16F877A Microcontroller it collects the data from the sensors and sends the data through IOT. The Protected data sent can be access anytime by the doctors by typing the corresponding exclusive IP address in any of the Internet Browser at the end user device (ex: Laptop, Desktop, Tablet, Mobile phone).
The Microcontroller is connected to IOT which provides information to doctor/caretaker when the heart rate is greater than 90 or less than 60 and when the temperature is less than 20 or greater than 35. LCD is connected to microcontroller to display the transaction process and healthcare data. And the user interface html webpage will automatically refresh for every 15 seconds for this reason patient health status is continuously send to the doctor.
Therefore continuous monitoring of patient data is achieved. Meria M George, Nimmy Mary Cyriac, Sobin, Mathew,Tess Antony, This paper proposes a patient health monitoring system using IoT and android. It consist of temperature sensor ECG sensor, Heartbeat sensor and accelerometer. This sensors are connected to Arduino board. The values from microcontroller is given to web server using Ethernet shield. The parameter values can be viewed by android application installed in doctors and patient smartphones.
The health parameter are stored and published online. Hence, the healthcare professional can monitor their patients from a remote location at any points. Duddela Dileep Kumar1& Pratti Venkateswarlu, This model proposes a “Secured Smart Healthcare Monitoring System Based on IOT” the model consists of ATMEGA8 Microcontroller, Temperature sensor (LM35), Pulse Oximetry Sensor (TCRT1000), Liquid Crystal Display (16×2), GSM MODEM, Electric Buzzer and Regulated Power Supply. In thissystem ATMEGA8 Microcontroller collects the data from the sensors andsends the data to Web page. The Protected data sent which can beaccessed anytime by the doctors by typing the corresponding uniqueURL address in any of the Internet Browser at the end user device.ArunaDevi.
S , GodfreyWinster.S, Sasikumar.S,This paper proposes a “Patient Health MonitoringSystem (PHMS) Using IoT Devices”The architecture of PHMS contains three phases; they are collectionphase, transmission phase, utilizationphase.
Body AreaNetwork (BAN) is constructed to collect the required data from thepatient. The parametersused to diagnose thedisease may vary from one disease to another. Therefore eachparameter is sensed byseparate IoT deviceswhich are connected to the patient.
All the devices connected in thebody of the patient areknown as BAN in thedata collection phase. Blood pressure module, heart rate monitor,temperature etc. are the basic devices used to collect the bloodpressure, heart rate and temperature of the patient. The transmissiondevice used in the transmission phases are Wi-Fi or Bluetooth .
Amobile application design for the doctor to check the health statusof the patient which is adapted in every 60 seconds after update inthe served. The data collected from the IoT devices to the system isused and the information only for last three days can be viewed inmobile application.
