<span lang="EN-US">An internet of things (IoT) irrigation system is challenged by several issues, such as cost, energy consumption, and data storage. This paper proposes a novel energy-efficient, cost-effective IoT system called "NewAgriCom" to monitor agricultural field water flow. NewAgriCom works with an embedded energy harvesting system, is an autonomous remote supervisory control and data acquisition (SCADA) based on a general packet radio service (GPRS) cellular network that effectively communicates irrigation field data to the Node.js server using SIM808 EVBV3.2 modem. In javascript object notation (JSON) format, data is transmitted over the hypertext transfer protocol (HTTP) protocol to the MySQL database. Then data are transferred to the proposed IoT platform, which gives us a hand to control actuators, visualise, store and download the data. NewAgriCom can significantly reduce water consumption. It can set a schedule to control water automatically at specific times in various modes, including normal, light, and deep sleep modes. It regularly provides the location, time, signal strength, and the state of actuators with the identifier of every device remotely on the IoT Platform.</span><p> </p>

Nowadays, information represents an important resource for any organization and to ensure its management, it is important to set up an information system. The latter being essential in various fields, it can bring improvements in the care of patients and in the quality of health services. However, the use of information and communication technologies on the quality of health services was exclusive in developed countries. It is with this in mind that we have focused our study on the proposal of architecture to make hospital intelligent based on the Internet of Things (IoT) and the Blockchain. To do this, we used three databases namely Scopus, Web of Science and PubMed. First, we collected references to open-source Hospital Information Systems (OS HIS) and we were able to extract thirteen popular projects of which seven are active and 6 are not. Then, we continued our study with the seven active projects. Second, we collected references to IoT architectures for healthcare and after extensive reading we opted for a three-layer architecture (perception layer, network layer and application layer). Third, we collected references to lightweight blockchains and after in-depth reading of the documents found, we selected the Hyperledger foundation which was created to ensure the promotion of blockchain through an open-source ecosystem. As a result, we were able to come up with a three-layer architecture which is on the concepts of IoT and Blockchain. The proposed work is promising and can be used as a reference for the deployment of a hospital information system in an environment with limited resources.
