Design of an internet of things based real-time monitoring system for retired patients

The main aim of this article is to design a monitoring center for collecting and evaluating the physiological function of retired patients in nursing homes. The system should be able to collect the information of body heat, heart rate, blood oxygen, orientation, and sleep time in the form of the little bracelet. The evaluating part of the system with the program can be placed into personal computer (PC) which can provide a user-friendly interface and easy managing. The program can display all needed information of the patient from previous days or months in the form of the graphs and the nursing person can have the view of the patient´s physiological health. The evaluation and the collection of the data from each patient are done only on the card and the computer is only a device for live-view and managing. In case of the power failure, the monitoring system will be still operating normally due to the uninterruptible power supply (UPS) in the form of the battery. It means that the system will operate even if the PC is powered off. The system also has several external communication interfaces like wireless fidelity (Wi-Fi), ethernet, and general packet radio service (GPRS) which provides an external connection.

Design and Implementation of Healthcare Patient based General Packet Radio Service

In recent years the health monitor systems for patients was developed by using wireless technologies such as Internet of Things (IoT), Wireless Sensor Network (WSN), or Websites. In this research a patient's position in Google map, heartbeat rate, and temperature were measured and transmitted to the family or doctor based GPRS technology via the smartphone and microcontroller. This system has advantages of low cost design, Early warning of patient status through SMS message or email, position recognize based on GPS and fast of treatment patient.

Low-Cost and Ultra-Low-Power Consuming RTUs for Use in IoT Systems

This paper presents the design and realization of low-cost and ultra-low-power consuming remote transfer units (RTUs), working as communication gateways for collecting, aggregating, and forwarding IoT data to information centers (servers) in the cloud for further processing and data mining. Two types of RTUs, targeting different application scenarios and utilizing different communication standards, were designed – one, based on the General Packet Radio Service (GPRS) standard, and another – on the NarrowBand Internet of Things (NB-IoT) standard. The developed RTUs were experimentally tested and their use was successfully demonstrated in different IoT systems.

Control and indicating equipment communicating via the peripheral component interconnect express bus

Nowadays, the Intruder Alarm system is commonly used to protect the life, health and the possession of people in big companies. However, these systems have limited options for managing and remote control. This lack is very often criticized by big companies which want to use the Intruder Alarm System with other applications like Access and Attendance control. The aim of this article is to design a Control and Indicating Equipment which can be implemented into commercially made Personal Computer as expansion card. The designed card provides the main function of the Intruder Alarm system which can be further extended by other applications. The system consists of external communication like Universal Serial Bus, Ethernet and General Packet Radio Service interface. Each individual part of the system is driven by a single microcontroller ATmega328P which can handle communication and evaluation of the current state obtained by devices connected to it. The design can offer all alarm and non-alarm visualization of smart control like irrigation, lights control, audio system, etc. The whole design is driven by the proper standardization and the design consists of every schematic which comes with the explanation

Cloud-Based Vehicle Tracking System

The need for vehicle tracking system in real time is growth continues due to increase the cases of theft. This type of system in real time needs to transmit large data with huge number of HTTP request to the server to keep tracking and monitoring in real time, thus causes spend extremely high cost every month for transportation the information on tracking vehicles to server therefor the needs for reducing the number of transportation and data size that transmits in each HTTP request to save expenses. This paper designed and implement an integrated vehicle tracking system in real time to track vehicle anywhere and anytime. This system is divided into two parts: vehicle tracking part and monitoring part. Tracking part is represented by installation the electronic devices in the vehicle using modern Global Positioning System (GPS), microcontroller Arduino UNO R3 and SIM800L GSM/GPRS modem. GPS is determined location of the vehicle via received coordinates from satellites such as latitude and latitude with accuracy ranging approximately 2.5 meters; the coordinates faked to add a type of protection to information on vehicles without effecting on characterizing real time tracking before sending it via a General Packet Radio service (GPRS). The monitoring part is in the cloud and will receive the coordinates and displays it on a map in a web page. The main contribution of this system is it reduced data size that sent from in-vehicle device via selected only necessary data for tracking vehicle from NEMA sentences of GPS and reduced number of HTTP request that sent to remote server via constrain the transmission of information with the movement of vehicles, since when vehicle moved the coordinates each 10s and did not send anything when the vehicle stopped thus will reduce the cost of expenses every month. This system can be utilized to track and monitoring the vehicles of large universities, companies, organization and also can be used in army vehicles and police vehicles.

A Performance Analysis of General Packet Radio Service (GPRS) and Narrowband Internet of Things (NB-IoT) in Indonesia

Internet of Things (IoT) refers to a concept connecting any devices onto the internet. The IoT devices cannot only use a service or server to be controlled at a distance but also to do computation. IoT has been applied in many fields, such as smart cities, industries, and logistics. The sending of IoT data can use the existing GSM networks such as GPRS. However, GPRS is not dedicated particularly to the transmission of IoT data in consideration of its weaknesses in terms of coverage and power efficiency. To increase the performance of the transmission of IoT data, Narrowband-IoT (NB-IoT), one alternative to replace GPRS, is offered for its excellence in coverage and power. This paper aims to compare the GPRS and NB-IoT technology for the transmission of IoT data, specifically in Bandung region, Indonesia. The results obtained showed that the packet loss from clients for the GPRS network was at 68%, while the one for NB-IoT was at 44%. Moreover, NB-IoT technology was found excellent in terms of battery saving compared to GPRS for the transmission of IoT data. This result showed that NB-IoT was found more suitable for transmitting the IoT data compared to GPRS.

This paper presents the bibliographic review of smart systems implemented so far and their application. Also this paper is dedicated to new smart mobile system developed for monitoring microclimatic parameters. This system is primarily intended for monitoring real-time microclimatic parameters, such as air quality where the presence of carbon monoxide (CO) is monitored, as well as other microclimatic parameters. The mobile system which will be described in this manuscript can be installed in public transport (to obtain information on microclimatic parameters on a known route). Also, to obtain information on microclimatic parameters from a random route, it is possible to install the system in a taxi vehicle. This system provides the ability to generate a map using the data provided by the system based on GPS coordinates.
