Research ArticleOpen accessEvery word in the titleA Conflict-Free Routing Tables Update Method for Persistent Multilink and Node Failures in SDN ArchitecturesYannick Florian Yankam, Jean Frédéric Myoupo, Vianney Kengne TchendjiThe large-scale network management abilities of centralized architectures, such as Software-Defined Networking (SDN), are attracting increasing interest from major computer networking companies. In this architecture type, the nodes follow the rerouting rules predefined by the control plane in the controller. However, when a link or node failure becomes persistent over the time, the controller must recompute the routing and rerouting … …Journal of Computer Science, Vol. 15, Issue 3 · 11 Mar 2019 · 7,473 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTPAL: A Protocol for Node Authentication in IoTMohamad Faiz Razali, Mohd Ezanee Rusli, Norziana Jamil, Salman YussofSecure communication in Low power and Lossy Network (LLN) requires the authentication of the identities of nodes for that node to join the network. Since LLN may consist of many different nodes, where some nodes may contain sensitive and subtle information such as military data, monitoring data, or health data, that node needs to be authenticated before it can deliver … …Journal of Computer Science, Vol. 14, Issue 10 · 30 Oct 2018 · 7,031 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePro-Active Prevention of Clone Node Attacks in Wireless Sensor NetworksK. M. Anandkumar, C. JayakumarProblem statement: Wireless mobile sensor networks are deploying large, self-organized and adaptable sets of sensors for many applications such as military, environmental, health care, remote monitoring and other applications. Unfortunately, the simplicity and low-cost of these sensors make eases cloning of compromised nodes by attackers in the network. Due to the unattended nature of wireless sensor networks, an adversary can … …Journal of Computer Science, Vol. 8, Issue 10 · 28 Aug 2012 · 7,075 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Wireless Sensor Node Supporting Various Powers Supply and Communication MethodsStefan Gruber, Hannes Reinisch, Hartwig Unterassinger et al.Problem statement: This study presents a wireless sensor node dedicated for in-tire pressure and temperature monitoring. Additional features set it apart from the many different systems available on the highly competitive market. State-of-the-art implementations are mounted on the rim of a tire. Here the sensor node will be mounted on the inner liner of the tire. By moving the sensor … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 8,035 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLink Stability and Node Energy Conscious Local Route-Repair Scheme for Mobile Ad Hoc NetworksAnuradha Banerjee, Paramartha DuttaProblem statement: A mobile ad hoc network is a self-configuring network of mobile nodes connected by wireless links. As the nodes are free to move randomly, topology of the network may change rapidly and unpredictably. As a result, intermediate nodes in the communication routes tend to lose connection with each other during the communication process. In order to repair a … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,862 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnt Colony Based Node Disjoint Hybrid Multi-path Routing for Mobile Ad Hoc NetworkB. Kalaavathi, K. DuraiswamyMobile Ad hoc Networks are characterized by multi-hop wireless links, without any infrastructure and frequent node mobility. A class of ant colony based routing protocols has recently gained attention because of their adaptability to the network changes. AntHocNet is ant colony based hybrid algorithm, which combines reactive path setup with proactive path probing, maintenance and improvement. Multi-path routing represents a … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,047 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePiezoelectric Co-Rotational 3-Node Shell ElementGil Rama, Dragan Marinkovic, Manfred ZehnGeometrically nonlinear FE-analysis of active piezoelectric thin-walled shell structures, based on a Co-Rotational (CR) formulation and the Cell-Smoothed Discrete-Shear-Gap 3-node shell element (CS-DSG3) is presented in this study. The electric potential across the thickness of piezolayers is approximated by a linear function. The basic assumption of the applied Co-Rotational (CR) FEM formulation is that translations and rotations are finite, whereas … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 15 Oct 2016 · 7,816 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBIFURCATION ANALYSIS OF EQUILIBRIUM POINT IN TWO NODE POWER SYSTEMHalima Aloui, Faouzi Bacha, Moncef GasmiThis study presents a study of bifurcation in a dynamic power system model. It becomes one of the major precautions for electricity suppliers and these systems must maintain a steady state in the neighborhood of the operating points. We study in this study the dynamic stability of two node power systems theory and the stability of limit cycles emerging from … …American Journal of Applied Sciences, Vol. 11, Issue 4 · 29 Jan 2014 · 7,062 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePERFORMANCE COMPARISON OF HUFFMAN AND LEMPEL-ZIV WELCH DATA COMPRESSION FOR WIRELESS SENSOR NODE APPLICATIONAsral Bahari Jambek, Nor Alina KhairiWireless Sensor Networks (WSNs) are becoming important in today’s technology in helping monitoring our surrounding environment. However, wireless sensor nodes are powered by limited energy supply. To extend the lifetime of the device, energy consumption must be reduced. Data transmission is known to consume the largest amount of energy in a sensor node. Thus, one method to reduce the energy … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,949 accessesView PDFCite
Case ReportOpen accessEvery word in the titleIntestinal Mucinous Adenocarcinoma with Lymph Node Metastasis in a CatHandan Hilal Arslan, Hatice Ozlem Nisbet, Efe Karaca et al.Intestinal adenocarcinoma is a malignant tumor. The most common clinical signs of gastrointestinal adenocarcinoma are depression, anorexia, loss of weight, vomiting, diarrhea or constipation due to obstruction. In cats, gastrointestinal adenocarcinomas are the most common non-hematopoietic gastrointestinal tumors and their frequency is higher in males. In this report, the case of an 8 year old male cat with adenocarcinoma that … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 3 · 17 Aug 2017 · 8,897 accessesView PDFCite
