Research ArticleOpen accessPhrase in the titleEnhanced Preemptive Global Utility Accrual Real Time Scheduling Algorithms in Multicore EnvironmentIdawaty Ahmad, Mohamed Othman, Zuriati Ahmad ZulkarnainThis paper proposed an efficient real time scheduling algorithm using global scheduling paradigm running in multicore environment known as Global Preemptive Utility Accrual Scheduling (GPUAS) algorithm. The existing TUF/UA multiprocessor scheduling algorithms known as Greedy-Global Utility Accrual (G-GUA) and Non Greedy-Global Utility Accrual (NG-GUA) algorithms is seen to overlook the efficiency on its task scheduling algorithm. These algorithms have adapted … …Journal of Computer Science, Vol. 11, Issue 12 · 11 Feb 2016 · 6,390 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePerformances of Partition Utility Accrual Real Time Scheduling AlgorithmIdawaty Ahmad, Shamala Subramaniam, Mohamed Othman, Zuriati ZulkarnainProblem statement: This study proposed a TUF/UA real time scheduling algorithm known as Partition Preemptive Utility Accrual Scheduling (PUAS) also known as PPUAS algorithm. This algorithm addressed the overloaded problem that was identified in a uniprocessor scheduling environment and the necessity to design the scheduling algorithm in a multiprocessor environment. Approach: The PUAS algorithm was enhanced into the partitioned multiprocessor … …Journal of Computer Science, Vol. 8, Issue 8 · 12 Jul 2012 · 7,009 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Backward Recovery Mechanism in Preemptive Utility Accrual Real Time Scheduling AlgorithmIdawaty Ahmad, Muhammad Fauzan OthmanProblem statement: This study proposed a robust algorithm named as Backward Recovery Preemptive Utility Accrual Scheduling (BRPUAS) algorithm that implements the Backward Recovery (BR) mechanism as a fault recovery solution under the existing utility accrual scheduling environment. The problem identified in the TUF/UA scheduling domain is that the existing algorithms only considers the Abortion Recovery (AR) as their fault recovery … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,827 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTask 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 accessEvery word in the titleEnhanced Utility Accrual Scheduling Algorithms for Adaptive Real Time SystemIdawaty Ahmad, Muhammad Fauzan OthmanProblem statement: This study proposed two utility accrual real time scheduling algorithms named as Preemptive Utility Accrual Scheduling (PUAS) and Non-preemptive Utility Accrual Scheduling (NUAS) algorithms. These algorithms addressed the unnecessary abortion problem that was identified in the existing algorithm known as General Utility Scheduling (GUS). It is observed that GUS is inefficient for independent task model because it simply … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,352 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtility-based Scheduling Frameworks for Efficient Quality-of-Service Differentiation in a Mixture of Real-time and Non-real-time TrafficsOlalekan Bello, Hushairi Zen, AL-Khalid Othman, Khairuddin Abdul HamidThis paper proposes a utility-based scheduling framework for efficient differentiation of users’ Quality-of-Service (QoS) in a broadband wireless access system involving heterogeneous mixed traffic flows. The utility-based scheduling framework, called Maximum QoS Satisfaction (MQS), is based on three novel Radio Resource Allocation (RRA) techniques; delay-based scheduling policy for Real-Time (RT), minimum-rate-based scheduling policy for Non-Real-Time (NRT) and a throughput-based scheduling … …Journal of Computer Science, Vol. 11, Issue 7 · 19 Oct 2015 · 7,139 accessesView PDFCite

Research ArticleOpen accessIn the keywordsFeasibility Analysis of Non-Preemptive Periodic Systems from Infeasibility PerspectiveNasro Min-AllahDue to simple implementation, non-preemptive scheduling has the advantage over preemptive counterpart when it comes to deployment of real-time systems. Accordingly, many feasibility techniques have been established to answer schedulability of the task set for non-preemptive case. The time complexity of exact condition for non-preemptive under dynamic priority assignment is of pseud-polynomial nature. Recently, efforts are made to decrease the … …Journal of Computer Science, Vol. 15, Issue 9 · 9 Sep 2019 · 7,617 accessesView PDFCite
