Research ArticleOpen accessIn the abstractTopology Discovering and Power saving Mechanism for Routing in a Tree of Ad-hoc Wireless NetworksArwa ZabianPower management in mobile network is an open challenges where the power level in the network influences the network life time. However, there are a trade off between the power consumption and the connectivity in mobile networks. We present a topology control mechanism and a routing protocol for Ad-Hoc wireless networks that chooses the shortest path given the lower power … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Intelligence Based Three-Phase Unified Power Quality ConditionerMoleykutty GeorgePower quality is an important measure of the performance of an electrical power system. This paper discusses the topology, control strategies using artificial intelligent based controllers and the performance of a unified power quality conditioner for power quality improvement. UPQC is an integration of shunt and series compensation to limit the harmonic contamination within 5 %, the limit imposed by … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractDamping of Generator Oscillations Using an Adaptive UPFC-based ControllerD. Nazarpour, S. H. Hosseini, G. B. GharehpetianIn this study a UPFC-based non-linear adaptive controller is proposed and designed to damp generator oscillations. The adaptive controller design is based on determination of control signal using a new linear quadratic pole placement control law and identification of power system parameters with recursive least squares method with adaptive directional forgetting factor. A new model of UPFC has been introduced … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,764 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview of Charge Pump Topologies for Micro Energy Harvesting SystemsMichelle Lim Sern Mi, Md. Shabiul Islam, Jahariah Sampe, Sawal Hamid Md. AliThis paper reviews CMOS based charge pump topologies used within autonomous embedded micro-systems. These charge pump structures have evolved from its simplistic diode-tied, single-branches with major threshold drops to exponential type, dual-branches with sophisticated gate and substrate control for lower voltage operation. Published charge pumps are grouped based on architecture, operation principles and pump optimization techniques with their pros and … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractTRAFFIC CONTROLLED-DEDICATED SHORT RANGE COMMUNICATION: A SECURE COMMUNICATION USING TRAFFIC CONTROLLED DEDICATED SHORT RANGE COMMUNICATION MODEL IN VEHICULAR AD HOC NETWORKS FOR SAFETY RELATED SERVICESK. Chandramohan, P. KamalakkannanTo increase the road safety and secure communication among the vehicles in the network environment, Dedicated Short Range Communication (DSRC) is followed. Nowadays, research over DSRC is dramatically increased for enhancing the road safety applications. The main task of DSRC is to protect the vehicles by communicating the warning message regarding the vehicle changing conditions, traffic occurrence and dangers over … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 6,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractA BROADCAST BASED ROUTING PROTOCOL FOR INTER-CLUSTER DATA DISSEMINATION IN VEHICULAR COMMUNICATIONAuxeeliya Jesudoss, S. V. Kasmir Raja, Ashraph SulaimanVehicular communication is one of the fast growing and promising technologies for a safe and comfortable driving environment. These technologies do not end up with economic and safety ramifications, but also extended with other informational and entertainment oriented services. Data are being propagated multi-hop between source and destination vehicles for many real-life applications. Clustering is one of the effective and … …Journal of Computer Science, Vol. 10, Issue 5 · 30 Dec 2013 · 7,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality of Service Aware Reverse Pathad-Hoc On-Demand Distance Vector ProtocolK. G. Santhiya, N. ArumugamMobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticost Routing Approach in Wireless Ad hoc NetworksD. Loganathan, P. RamamoorthyProblem statement: A Wireless ad hoc network is a collection of autonomous movable nodes that communicate with each other over wireless links without any static infrastructure. In these networks there is no fixed topology because of the mobility of nodes, interference, multipath propagation and path loss. A variety of routing protocols and algorithm with varying network settings are analyzed to … …Journal of Computer Science, Vol. 8, Issue 10 · 30 Aug 2012 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Path Management Mechanism to Mesh Base Stations in WiMAXSahar Abdul Aziz Al-Talib, Noor Raad SaadallahThree options are popular today for design of wireless networks - Point-to-Point, Point-to-Multipoint and Mesh topologies. Worldwide interoperability of microwave access (WiMAX) is most often associated with the point-to-multipoint (PMP) topology. For some requirements, the configuration of the base stations (BSs) is aimed to be as mesh. Mesh offers a combination of point-to-point and point-to-multipoint capability by having each of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 22 Mar 2019 · 7,972 accessesView PDFCite
