Research ArticleOpen accessEvery word in the titlePerformance Comparison of Passive Fault Tolerant Control Strategy with PI and Fuzzy Control of Single-Tank Level Process with Sensor and System FaultHimanshukumar R. Patel, Vipul A. ShahFault-Tolerant Control (FTC) strategy has gain maximum attention in recent years in chemical industries due to economical and safety hazards perspective. Targeting at the decreasing control performance of the single-tank level control process under the constraint of system and sensor faults, this article presents model-based Passive Fault-Tolerant Control (PFTC) strategy which are based on conventional and artificial intelligence control. The … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 24 Jun 2019 · 7,598 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDevelopment of Ionizing Radiation Sensors Based on Carbon NanotubesKenneth Fontánez, Abraham García, María del C Cotto-Maldonado et al.SWNTs have been efficiently grown on patterned substrates, for its subsequent application to the development of ionizing radiation sensors. SWNTs before and after exposure to X-rays were characterized by Raman and XPS spectroscopy, revealing the appearance of alterations that have been justified as possibly due to the presence of adsorbed oxygen species. These materials have been used for the fabrication … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 29 May 2019 · 7,191 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImplementation of Homomorphic Encryption for Wireless Sensor Networks Integrated with Cloud InfrastructureChristophe Ishimwe Ngabo, Omar El BeqqaliWith the current explosion of cloud services, it is easy for everyone to store the prodigious amount of data on remote servers. On the other hand, service providers are given full access to our information, or in the worst case, can be intercepted by malicious people. The solution is to encrypt the data to make it completely secret. But then, … …Journal of Computer Science, Vol. 15, Issue 2 · 8 Feb 2019 · 7,668 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative Study of Mobility Models for Wireless Sensor NetworksAnas Abu TalebWireless sensor networks consist of hundreds or thousands of small, lightweight and low-powered sensor nodes that are deployed in the area of interest to collect information in an unattended manner. Since sensor nodes have limited battery, many research papers proposed techniques to enhance the performance and lifetime of wireless sensor networks. Using energy rich mobile sink to collect data from … …Journal of Computer Science, Vol. 14, Issue 10 · 10 Oct 2018 · 8,063 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Security of the Sensor Cloud Security Library (SCSlib)Mohamed Rasslan, Mahmoud Nasreldin, Ghada Elkabbany, Aya ElshobakyNowadays, cloud computing has experienced remarkable growth. Indeed, one of the main challenges of cloud computing is to protect data from different sensor devices during processing and storing. In 2014, Henze et al. proposed the Sensor Cloud Security library (SCSlib) which allows cloud developer to access encrypted sensor data stored in the cloud. SCSLib drawback is that it allows a … …Journal of Computer Science, Vol. 14, Issue 6 · 23 May 2018 · 8,072 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWNBLI - A Multifarious Liability Examination for Wireless Sensor NetworksTamilarasi B., UmaRani R.Wireless communications has completely revolutionized the living environment, just as personal computers forever altered the way of working in the 1980’s and the Internet dramatically changed the obtainment and accessing way of information in the 1990’s. Wireless sensor networks are evolving to a new level. The Failure liability is a very prominent problem in Wireless Sensor Network (WSN) research.

Research ArticleOpen accessEvery word in the titleInter Cluster Group Management in Wireless Sensor NetworksR. Rohini, Adamu Murtala Zungeru, S. Ravi, Dasari Narasimha RaoWireless Sensor Networks (WSNs), an emerging large-scale network system can be embedded for any application. The designers of wireless sensor network have to consider the quality of service agreements from a user perspective. The WSN is very rapid in dynamic changing topology and has less energy, computing and communication resources. The network design has to fulfill the QoS parameters like … …Journal of Computer Science, Vol. 14, Issue 4 · 19 Apr 2018 · 7,988 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFDIR Strategy for Sensor Faults During Re-entry FlightGianfranco Morani, Mariangela Di LorenzoIn this study, a Fault Detection, Isolation and Reconfiguration (FDIR) strategy is proposed for dealing with the problem of single sensor faults during a re-entry flight. The proposed algorithms rely on a model based Fault Detection and Isolation. After the generation of a residual through a Kalman filter observer, detection is obtained via the estimation of residual signal statistics while … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 7 Apr 2018 · 8,690 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Routing Optimization Based on Cross-Layer Design for Wireless Multimedia Sensor Networks (WMSNs)Emansa Hasri Putra, Risanuri Hidayat, Widyawan, Wayan MustikaMultimedia applications are routed from source nodes via neighboring nodes to a sink in Wireless Multimedia Sensor Networks (WMSNs). However, the existing routing protocols in the WMSNs do not fulfill the quality of service (QoS) constraint yet for multimedia transmission. The WMSNs have specific characteristics such as multi-hop way, limited node capability and varying bandwidth, which can affect the quality … …Journal of Computer Science, Vol. 13, Issue 10 · 31 Oct 2017 · 7,396 accessesView PDFCite
