Research ArticleOpen accessIn the abstractE2AODV Protocol for Load Balancing in Ad-Hoc NetworksR. Vinod Kumar, R. S.D. Wahida BanuProblem statement: In mobile ad hoc networks there are a number of challenges in providing quality of service routing with energy efficiency and load balancing. Most routing protocols do not consider the problem of load balance. A routing protocol called energy Efficient Ad-hoc on Demand Vector (E2AODV) is proposed. It addresses the quality of service issues such as throughput, end … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jul 2012 · 6,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Threshold based Scheduling for Multi-User Multiple-Input Multiple-Output SystemsK. Chanthirasekaran, M. A. BhagyaveniProblem statement: Multi-User Multi-Input Multi-Output (MU-MIMO) system had eventually used in 4th generation wireless networks either to achieved diversity gain or multiplexing gain. Many recent scheduling addresses the threshold based resource allocation where in resource were not utilized properly. Approach: In this study a new Multi Threshold Based Channel Aware Scheduling (MTCAS) was proposed for performance improvement and proper resource … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mosquito Repellent on the Transmission Model of Chikungunya FeverSurapol Naowarat, Prasit Thongjaem, I. Ming TangProblem statement: In 2008 there was a large outbreak of Chikungunya fever in southern Thailand. Chikungunya fever is an emerging disease which tends to affect rubber plantation and fruit orchard workers more than other occupation. This study we considers the efficacy of using mosquito repellent as a way to prevent and control the spread of Chikungunya fever. The mathematical model … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 14 Feb 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamical Model for Determining Human Susceptibility to Dengue FeverSurapol Naowarat, Thanon Korkiatsakul, I. Ming TangProblem statement: Mathematical models are a useful tool for understanding and describing the transmission of diseases such as dengue fever, one of the most prevalently emerging diseases common to tropical and subtropical areas throughout South East Asia. By taking into account human susceptibility to disease, the dynamics of a dengue disease model is proposed. Approach: Using standard methods for analyzing … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 28 Sep 2011 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractColored Image Compression Using Gradient Adjustment Prediction Based WaveletMuna Faik Hanoon Al-SammraieProblem statement: Uncompressed graphics, audio and video data require considerable storage capacity and transmission bandwidth. Despite rapid progress in mass-storage density, processor speeds and digital communication system performance, demand for data storage capacity and data transmission bandwidth continues to outstrip the capabilities of available technologies. The recent growth of data intensive digital audio, image and video (multimedia) based web applications, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Computer Based Clinical Programming Software for Auditory ProsthesesK. Rajakumar, P. Seetha RamaiahAuditory Prostheses (AP) are widely used electronic devices for patients suffering with severe to profound senosorineural deafness by electrically stimulating the auditory nerve using an electrode array surgically placed in the inner ear. AP mainly contains external Body Worn Speech Processor (BWSP) and internal Implantable Receiver Stimulator (IRS). BWSP receives an external sound or speech and generates encoded speech data … …Journal of Computer Science, Vol. 5, Issue 8 · 31 Aug 2009 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneric Algorithm with Varying Block Sizes to Improve the Capacity of a Wireless Communications NetworksMahmoud AbdellaouiProblem statement: Channel capacity can be an essential parameter for wireless communication to improve the link quality. Until now, the channel capacity has been evaluated by utilizing Shannon capacity theory, but it presented many limitations and restrictions. The objectives of this study were to: (i) Expose, quantify, present and to give a clear and concise exposition of the mathematical principles … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Near Real-time Early Warning System on Erosion HazardsFaisal H. Ali, Tew K. HuiWith many incidences of landslides, mudslides and erosion occurrences lately, especially in the highlands in Malaysia, properties were damaged and lives were lost. Seeing the need of resolving and minimizing such untoward incidences, a study has been embarked on developing a near real-time early warning system on erosion hazards so as to provide an early warning to the public, whenever … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,706 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMinimizing Transmission Time under Required System Capacity Constraint in Stochastic-Flow NetworksMoatamad Refaat HassanIn the case of an existing limited capacity of the system called required system capacity, in this study a new method is presented to determine the disjoint paths to send data from the source to the sink. System reliability is evaluated as the probability that a specified amount of data can be transmitted from a source to a sink through … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 5 May 2018 · 7,672 accessesView PDFCite
