Research ArticleOpen accessEvery word in the titleEnhanced Lifetime Maximization Using Metaheuristics-Based Unequal Clustering With Routing Protocol on Wireless Sensor NetworksN. E. Kanaghadhara, R. SubanThe Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors that monitor environmental or physical factors such as sound, pressure, or temperature, and pass the information directly through the network to a sink or central location. Clustering and routing are essential in WSNs to optimize their longevity, scalability, and efficiency. Clustering includes grouping Sensor Nodes (SN) into clusters, each … …Journal of Computer Science, Vol. 22, Issue 7 · 21 Jul 2026 · 682 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntrusion-Resistant Multi-Hop Communication Protocol for Secure Wireless Sensor NetworksRakesh Ranjan, Vaishali Singh, Hitendra SinghModern Internet of Things (IoT) systems are based on Wireless Sensor Networks (WSNs), which can be distributed to various environments to perform a range of sensing and data aggregation. Their intrinsic deficiencies in computation, energy, and bandwidth, however, make them very vulnerable to routing-layer attacks like black hole and selective forwarding as well as Sybil intrusion. The current studies on … …Journal of Computer Science, Vol. 22, Issue 6 · 1 Jul 2026 · 935 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProbe-based Semi-permanent Soil Humidity SensorSoobin Jeon, Dongmahn SeoThe modern agricultural environment has the problems of an aging rural population and a decreasing rural labor population. Recently, smart farms based on information and communication technology have been studied to address environmental issues in agriculture. The smart farm consists of three parts: a data collection unit, a processing unit, and a control unit. Among them, the data collection unit … …Journal of Computer Science, Vol. 21, Issue 10 · 16 Dec 2025 · 1,923 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleA Systematic Review on Wake-up Radios Applied to Wireless Sensor NetworksMarco Aurélio Spohn, Caetano Mazzoni Ranieri, Agnelo Rocha da Silva, Jó UeyamaWireless Sensor Networks (WSNs) are the backbone of many monitoring applications, especially in the Internet of Things (IoT) context. However, efficient power management becomes a critical challenge when sensor nodes rely on disposable batteries. The deployment of WSNs must ensure coverage and connectivity, but the resulting distribution of nodes and underlying protocols directly impact the network’s lifetime. The concept of … …Journal of Computer Science, Vol. 21, Issue 3 · 4 Feb 2025 · 6,201 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDelay-Conscious Service Quality Constraint in IoT Sensor Networks for Smart FarmingZatin Gupta, Amit Kumar BindalThe Internet of Things (IoT) offers different services for the agriculture industry, such as monitoring and analysing real-time data related to current weather conditions, water level, irrigation requirements, growth of plant disease and health status/temperature/humidity, etc.,). The performance of IoT networks may vary due to environmental conditions and operational areas (rural area/urban area/underwater). These constraints may degrade the transmission quality … …Journal of Computer Science, Vol. 19, Issue 8 · 9 Aug 2023 · 5,385 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStrengthening the Integrity of Forwarding First Communication Using Forward Key Chain and Bloom Filter in the Wireless Sensor NetworksMuhammad Taqqyyudin Ilham Ramadhan, Farah Afianti, Bambang Ari Wahyudi et al.Wireless Sensor Networks (WSNs) are collections of sensor nodes that can help people monitor things wirelessly, replacing the need for human presence in hard-to-reach areas. While forwarding first communication reduces communication delays among the sensor nodes, it lacks a security mechanism. Since sensor nodes have limited resources, using complex security measures can shorten their lifetime. This study proposes a protocol … …Journal of Computer Science, Vol. 19, Issue 3 · 14 Feb 2023 · 5,661 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnergy and Distance Aware Multi-Objective Firebug Swarm Optimization Based Clustering and Routing in Wireless Sensor NetworksGundeboyina Srinivasalu, Hanumanthappa UmadeviIn recent years, Wireless Sensor Networks (WSNs) have received increased international attention due to advancements in the communication, electronics, and information fields. These sensor networks integrate a huge number of sensor nodes to track rapidly changing physical events. The key improvement is that these nodes can be easily positioned in any environment due to their small size. Therefore, maintaining network … …Journal of Computer Science, Vol. 19, Issue 3 · 10 Feb 2023 · 6,029 accessesView PDFCite
