Research ArticleOpen accessIn the abstractEnergy Efficient Hidden Markov Model Based Target Tracking Mechanism in Wireless Sensor NetworksB. Amutha, M. PonnavaikkoProblem statement: Target tracking is a challenging application in Wireless Sensor Networks (WSNs) because it is computation-intensive and requires real-time location processing. This study proposes a practical target tracking system based on the Hidden Markov Model in a distributed signal processing framework. In this framework, wireless sensor nodes perform target detection and tracking, whereas target localization requires the collaborative signal … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Real Time Architecture for Data Placement in Wireless Sensor NetworksSanjeev Gupta, Mayank DaveProblem statement: Application scenarios of Wireless Sensor Networks (WSN) create interesting design challenges since the sensor nodes used to collect and communicate data may fail suddenly and unpredictably. The issue of real-time and reliable data delivery is extremely important for taking effective decisions in WSN. Approach: In this study we proposed architecture for reliable and real-time approach for data placement … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Aware Optimal Routing for Wireless Sensor NetworksS. Chandramathi, U. Anand, T. Ganesh et al.Wireless Sensor Network (WSN) is a collection of autonomous devices with computational, sensing, and wireless communication capabilities. The sensor nodes are low cost, multi-functional devices that are densely deployed either inside the phenomenon or very close to it and are often powered by independent power sources. The lifetime of such sensor nodes show a strong dependence on lifetime of the … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Image Component Transmission Approach to Improve Image Quality and Energy Efficiency in Wireless Sensor NetworksWei Wang, Dongming Peng, Honggang Wang, Hamid SharifDue to resource constraints, digital image transmissions are a significant challenge for image sensor based Wireless Sensor Networks (WSN). In this paper, we propose a novel robust and energy-efficient scheme, called Image Component Transmission (ICT) in WSN by providing various levels of reliability during image transmissions. Different components in the embedded wavelet image bit stream are considered and essential components … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,252 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnhanced 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 · 686 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMinimising Energy Consumption in WSN-IoT Networks by Focusing on Quality of ServiceAnuradha, Tarun Gulati, Rajbhupinder Kaur et al.IoT networks are low-powered networks and resource allocation and efficient utilization are critical concerns. Network resources are allocated to the intermediate nodes to perform the various operations (sense, transmit, re-transmit, data aggregation, etc.). These operations are managed by the different layers (M.A.C., routing and PHY). Each layer consumes resources W.R.T. their operations and there is a need to manage the … …Journal of Computer Science, Vol. 20, Issue 10 · 13 Aug 2024 · 4,984 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFault Node Detection and Connectivity Restoration with Mobile Relay Node in Wireless Sensor NetworksM.P. Anuradha, A.M. Swetha, Manivannan DoraipandianIn Wireless Sensor Network (WSN), node failure is an imperative concern in a hostile environment. These node failures create disjoints in the network and leads to a network partitioning problem. It is important for the nodes to be alive and communicate with each other to check the network connectivity. Replacement of Mobile Relay Nodes (MRN) in the location of faulty … …Journal of Computer Science, Vol. 16, Issue 4 · 1 Apr 2020 · 7,921 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnergy-Efficient Ant Colony-Based k-Hop Clustering and Transmission Range Assignment Protocol for Connectivity Construction in Dense Wireless Sensor NetworksGokou Hervé Fabrice Diédié, Boko Aka, Michel BabriConnectivity construction is the main phase of a communication-oriented topology control process.
