Research ArticleOpen accessIn the keywordsAPPLYING 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
Research ArticleOpen accessIn the keywordsTWO PHASE CLUSTERING METHOD FOR LEACH PROTOCOL FOR EFFECTIVE CLUSTER HEAD SELECTIONRathi, ViswanathanA Wireless Sensor Networks (WSN) comprise of a huge quantity of clusters of sensor nodes that can inter communicate with all nodes and with the base station through a wireless link. All clusters are corresponding to a cluster head to provide a direct communication to the base station and in addition with other cluster heads. Obviously well-organized selection of cluster … …Journal of Computer Science, Vol. 10, Issue 3 · 21 Nov 2013 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation Metrics for Wireless Sensor Network Security: Algorithms Review and Software ToolQasem Abu Al-Haija, Mohamed H. Shwehdi, Muhammad BanatWireless Sensor Networks (WSN) is currently receiving a significant attention due to their potential impact into several real life applications such as military and home automation technology. The work in this study is a complementary part of what’s discussed. In this study, we propose a software tool to simulate and evaluate the six evaluation metrics presented for non-deterministic wireless sensor … …Journal of Computer Science, Vol. 9, Issue 5 · 27 May 2013 · 7,348 accessesView PDFCite
Review ArticleOpen accessIn the keywordsPrison Perimeter Surveillance System Using WSNShereen Ismail, Eman Alkhader, Amal AhmadThe aim of this paper is to introduce a prison hybrid surveillance system using two main technologies; Wireless Sensor Network (WSN) and Unmanned Aerial Vehicles (UAVs). The system consists of three tiers; Wireless Underground Sensor Network (WUSN) in tier 0, Wireless Ground Sensor Network (WGSN) in tier 1 and Wireless Vision Sensor Network (WVSN) in tier 2 that consists of … …Journal of Computer Science, Vol. 13, Issue 11 · 4 Dec 2017 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDevelopment of Electronic Control Circuits for WSN: Towards a Livestock Tracking and Identification SystemObakeng Maphane, Oduetse Matsebe, Molaletsa NamosheBotswana’s beef sector contributes 0.3% of the total world beef exports, i.e. US$ 42.4 billion as of the year 2013 and her major market is the European Union (EU). Unfortunately, her failure to comply with the frequently changing European Commission (EC) export regulations on livestock tracking and identification means that beef export to this market is sometimes suspended. Research trends … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 4 Oct 2017 · 7,967 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance of Improved Directed Diffusion Protocol for Sensor Networks under Different Mobility ModelsK. E. Kannammal, T. PurusothamanProblem statement: In sensor networks, some routing protocols performance differs under different mobility models. In ns2, there are two kinds of directed diffusion protocols, rate based gradient mechanism (diffusion/rate) and probability based gradient mechanism (diffusion/prob). In this research, we proposed a method to improve the performance of Directed diffusion/prob protocol by adding a new interest message propagation mechanism and analyzed … …Journal of Computer Science, Vol. 8, Issue 5 · 25 Feb 2012 · 6,749 accessesView PDFCite

Research ArticleOpen accessIn the keywordsRemote Personal Tracking System (RPTS)Abdfatah A. Yahya, Mahmoud Z. IskandaraniA novel system for remote tracking of personnel was proposed. The system was based on assuring that the moving tracked code belongs to the actual person assigned such a code by smelling and temperature measuring the person who holds such a device. The system would operate using a specific RF signal and allows for an accurate, economic and secure environment … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 7,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Wireless Sensor Network Clustering Using a Hybrid Firefly–Bat Algorithm (HFBA)J. Jegan, Senthil kumar P, S. Saravanakumar et al.Wireless Sensor Networks (WSNs) are composed of numerous sensor nodes that collaborate to observe and evaluate various environmental parameters, transmitting the data to a central base station. Each node is equipped with a unique transmitter, receiver, and processor to facilitate sensing, processing, and communication. These networks are often installed in extremely remote and inaccessible areas. A significant challenge arises from … …Journal of Computer Science, Vol. 22, Issue 5 · 19 May 2026 · 1,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractLSTM-Based AI Model for Sinkhole Attack Detection With Legal Basis in an Ecuadorian Public InstitutionEstefanía Alejandra Mora Parra, Rubén Nogales Portero, Moisés Toapanta T. et al.Wireless Sensor Networks (WSN) are an essential component of the Internet of Things (IoT). However, their decentralized nature, data transmission over unencrypted channels, and the physical exposure of nodes make them especially vulnerable to attacks, among which the sinkhole attack stands out. This research aims to develop a machine learning–based model to detect sinkhole‐type attacks in wireless sensor networks, with … …Journal of Computer Science, Vol. 22, Issue 3 · 4 Mar 2026 · 1,648 accessesView PDFCite
