Research ArticleOpen accessIn the abstractParticle Swarm Optimization-Based Routing Protocol for Clustered Heterogeneous Sensor Networks with Mobile SinkR. Sudarmani, K.R. Shankar KumarIn Wireless Sensor Networks (WSN) sensor nodes with sensing, computing and communication infrastructure are randomly deployed and organized as clusters. Most of the existing sensor networks focus on homogeneous in which the cluster heads are changed periodically. To improve the lifetime of energy constraint battery powered WSN and to avoid energy sink-hole problem; Clustered Heterogeneous Sensor Networks (HSN) are analyzed … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 18 Mar 2013 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Closed Loop LCL-T Resonant DC-to-DC Converter Using Low Cost Embedded ControllerM. Annamalai, M. Vijaya KumarThe aim of this study is to simulate and implement open loop and closed loop controlled DC-DC converter for stand-alone wind energy system. Wind turbines, however, are not always very efficient in the wind speeds that are most common to a region. Typically, wind energy systems are designed to be highly efficient in high wind speed and have a cut-off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 6 Feb 2013 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Logic Based Power Control for Wideband Code Division Multiple Access Wireless NetworksN. Mohan, T. RavichandranProblem statement: Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required Quality of Service (QoS) parameters. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Efficient CAC is necessary for the QoS provisioning in … …Journal of Computer Science, Vol. 8, Issue 8 · 4 Aug 2012 · 6,755 accessesView PDFCite

Research ArticleOpen accessIn the abstractLink 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 · 6,856 accessesView PDFCite
