Research ArticleOpen accessIn the abstractAssessing the Usability of IoT-Based Smart Farming for Sustainable Organic AgricultureArisaphat Suttidee, Pankom Sriboonlue, Sompoch Tongnamtiang, Varitha LakkhamThis study evaluates the usability of an IoT-based smart farming system developed to support organic agriculture in Thailand. Many small-scale farmers still spend considerable time manually monitoring soil conditions and managing irrigation, often without access to practical technology. This slows farm operations and makes efficient water use more difficult. To address these challenges, the system was designed with wireless soil-moisture … …Journal of Computer Science, Vol. 21, Issue 10 · 7 Dec 2025 · 3,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Hybrid Power Module for Mobile Wireless Sensor Networks: Towards a Livestock Tracking and Identification SystemMolaletsa Namoshe, Oduetse Matsebe, Obakeng MaphaneSmart technology and Internet of Things (IoT) applications have gained popularity in the development of agricultural systems with Wireless Sensor Networks (WSNs) increasingly becoming the building blocks for IoT applications. However, WSNs have a limited power supply. As a result, these systems have a short lifespan, limited memory and low computing power. This paper describes the development of a hybrid … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Oct 2017 · 7,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation Wireless Adapter Interface Module with Gateway Device for Connection to 4-20 mA TransmittersWaleed Ishaq Hameed, K. Ivica, Amar Al-jzari, Yasir I. AbdulraheemWireless communication is emerging technology from the office world to the industrial world. It is important that this technique are applied by the users in industrial environments because the industrial communication underlies stricter conditions than office communication. In this paper, It has been designed and implemented wireless adapter interface module with gateway connected to 4-20 mA devices and the Differential … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 1 Jul 2017 · 8,027 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Review on Cognitive Radio for Next Generation Cellular Network and its ChallengesNandhakumar Pandi, Arun KumarCognitive Radio (CR) is considered an intelligent technology. It improves the utilization of the radio spectrum. The increasing number of new devices has resulted in growing congestion of the ISM bands. FCC issued an order only permitting unlicensed users (secondary users) to operate in white space without interfering with licensed users (primary users). Cognitive Radio Networks (CRNs) provides a solution … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 4 Apr 2017 · 8,986 accessesView PDFCite
Review ArticleOpen accessIn the abstractMEMS Based RF Energy Harvester for Battery-Less Remote Control: A ReviewNoor Hidayah Mohd Yunus, Jahariah Sampe, Jumril Yunas, Alipah PawiThe paper deals with the growing interest of energy harvesting systems due to great development in many new emerging technologies in electronics and telecommunication. The research focuses particularly about rectenna element comprises of antenna, impedance matching and rectifier.

Research ArticleOpen accessIn the abstractAPPLYING A HYBRID POLLING APPROACH BY SOFTWARE IMPLEMENTATION TO EXTEND THE LIFETIME OF A WIRELESS SENSOR NETWORKInácio Henrique Yano, Vitor Chaves de Oliveira, Mauricio Becker, Andreiwid Sheffer CorreaWireless Sensor Networks are networks suitable for data collection in harsh environments, where it would be difficult or costly the deployment of wired infrastructure. In spite of these advantages, such networks often rely on batteries to operate, which may lead to a serious limitation on the networks lifetime. Bearing this in mind, in this article is proposed and tested a … …Journal of Computer Science, Vol. 11, Issue 4 · 24 Jul 2015 · 7,013 accessesView PDFCite
