INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 8, ISSUE 12, DECEMBER 2019 ISSN 2277-8616 508 IJSTR©2019 www.ijstr.org Iot And WSN Based Smart Surveillance System For Patients With Closed-Loop Alarm Amit Sundas, Surya Narayan Panda Abstract: A smart surveillance system for patients is an emerging subject in the current time for health and safety patient‘s life in a remote location. In patient‘s surveillance system, sensor devices have an important function to communicate, collect data and analyze it for real-time applications. The precondition of the patient can be monitored and analyzed by using the various body sensors such as Spo2, Pulse, acceleration, temperature, etc. Sensors can be utilized to collect data from patient‘s body and send it to the remote location for analysis. This data can be used in the real-time application for monitoring the patients in a remote location. This paper discusses the state-of-art technologies that have been employed in literature for Smart surveillance system for patients. Also, the authors offered a novel architecture for a patient surveillance system that utilizes the concept of IoT (Internet of things) and WSNs (Wireless sensors networks). The proposed architecture acts as a surveillance system to monitor the patients with a closed-loop alarm which further help the concerned authorities to take the necessary and immediate action.

IoT has grabbed a reputed position in the field of technology. These days IoT is being used for almost every field that could be related to the research area, health science, security system or manufacturing of any devices. In short, IoT has made daily life easier and more reliable to live [1-2]. The major features of IoT are storing sensor data in real-time, sending real-time data in the cloud, accessing those data from anywhere [3]. The real-time data of sensor is stored by using any Wi-Fi module like NodeMCU, or Bluetooth modules like HC-05 with the help of Micro-controller or Microprocessor. As IoT grabbed a huge position over technology, on other side use of Wireless Sensor Networks (WSNs) has grown rapidly. Today's application based on network computing is faced with a huge demand for powerful functionalities network. The reach of the functional network is fundamental to customer satisfaction both in cloud computing as well as mobile network environments [24-26]. WSNs is a wireless network consisting of spatially scattered independent devices using sensors to continuously monitor environmental or physical conditions, such as sound, temperature, pressure, vibration, pollutants or motion, at various different locations [4-5]. A collection of sensing devices that can communicate wirelessly [6, 23]. By this generation of technology, sensors have become the most important object [4, 20-22]. Sensors are small in size but highly perfect for the features of sensing motion, pressure, and human touch even the atmosphere temperature [27]. The size and lightweight make the best advantages of sensors that help to design a device. The fetched data of sensors are processed with the help of an open-source programming language name Python [2,5]. Python is an open-source programming language which can be used to create computer software [6,28]. ThingSpeak is a cloud-based platform is used to store the sensor data in the cloud where ThingSpeak is also an open-source platform based on the cloud [4-5]. The motivation is to implement experimentation based on IoT and WSNs based smart surveillance system for patients with closed-loop alarm. The implementation of fetching real-time data of various wireless sensors and storing those data in a cloud-based platform. Various sensors used to measure pulse, acceleration, Spo2 and Temperature were used for this experiment. Purpose of using the pulse sensor is to detect the heart rate. Acceleration sensor to detect the movement or acceleration. Spo2 is used to evaluate the amount of oxygen present in the blood, or simply the percentage of hemoglobin contains oxygen. The temperature sensor is used to detect the body temperature. Before sending any data in cloud-first the data in real-time need to be fetched from the sensors. The outputs of fetched data in real-time were store in the cloud and shown in Android application in a closed loop. By the end, the experimental results are explained briefly. In this article, at first, we address several patients monitoring system based on IoT and WSNs. Then we propose a smart surveillance system for patients with closed-loop using IoT and WSNs. Therefore, the remainder of the article is organized as follows, starting with an introduction in Section 1. Section 2 is committed to the existing literature. Section 3 is defining the problem. Section 4 introduces the proposed work to monitor the patients. Section 5 finishes up the paper.
