Research ArticleOpen accessEvery word in the titleAnalysis of Hierarchical Diff-EDF Schedulability over Heterogeneous Real-Time Packet NetworksMoutaz Saleh, Zulaiha Ali OthmanPacket networks are currently enabling the integration of traffic with a wide range of characteristics that extend from video traffic with stringent QoS requirements to the best-effort traffic requiring no guarantees. QoS guarantees can be provided in conventional packet networks by the use of proper packet scheduling algorithms. As a computer revolution, many scheduling algorithms have been proposed to provide … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,530 accessesView PDFCite

Research ArticleOpen accessIn the keywordsIMPLEMENTATION OF CENTRAL QUEUE BASED REALTIME SCHEDULER FOR MULTIPLE SOURCE DATA STREAMINGV. Kaviha, V. Kannan, S. RaviReal-time data packet sources are required to remain robust against different security threats. This study proposes a real-time secure scheduling strategy for data transmission to enhance the communication throughput and reduce the overheads. The proposed system combines real-time scheduling with security service enhancement, error detection and realtime scheduler based on EDF algorithm using uc/os-II real time operating system, implemented on … …Journal of Computer Science, Vol. 10, Issue 9 · 22 Apr 2014 · 6,381 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImage Compression Algorithms Using Intensity Based Adaptive Quantization CodingSaad Al-Azawi, Said Boussakta, Alex YakovlevProblem statement: Low complexity image compression algorithms are necessary for modern portable devices such as mobile phones, wireless sensor networks and high constraint power consumption devices. In such applications low bit rate along with an acceptable image quality are an essential requirements. Approach: This study proposes low and moderate complexity algorithms for colour image compression. Two algorithms will be presented; … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 18 Jan 2012 · 8,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractTask Scheduling in Real Time Systems with Energy Harvesting and Energy MinimizationArvind Kumar, Bashir AlamEnergy is a major concern in battery operated real time devices (e.g. sensor nodes situated in remote areas) as battery life is solely responsible for the functioning of such devices. For such systems to work continuously and successively a regular source of energy is required. The lifetime of such systems can be increased by reducing the energy consumption and increasing … …Journal of Computer Science, Vol. 14, Issue 8 · 15 Aug 2018 · 8,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractA NEW-THRESHOLD BASED JOB SCHEDULING FOR GRID SYSTEML. RamaparvathyIn heterogeneous distributed systems, utility grids have emerged as a new model of service. In this service, workflow scheduling is one of the challenging problems for satisfying user’s quality requirements. One of the main issues in work flow scheduling is to minimize the workflow execution cost in terms of time and makespan. In this study, we propose a new workflow … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,785 accessesView PDFCite
