Task scheduling is one of the most \u0000important issues in cloud computing in order to enhance performance and \u0000resource utilization while minimizing costs. Because of its simplicity and \u0000fairness, the round-robin algorithm is the ideal task scheduling algorithm, \u0000although it suffers from time complexity and cannot handle outlier tasks. \u0000Several modifications of Round Robin have been introduced to enhance time \u0000complexity. To ensure sufficient deal with time complexity and outlier tasks, \u0000this paper introduces a novel enhanced round-robin heuristic algorithm by \u0000utilizing the round-robin algorithm and updating its time quantum \u0000dynamically based on the lower and upper quartiles of the time quantum for \u0000all the tasks in the ready queue. The experimental results on four datasets \u0000showed that the proposed algorithm significantly outperformed baseline \u0000algorithms in terms of the average waiting time, turnaround time, and \u0000response time. The results show that, when compared to the baseline \u0000algorithm in cases 3 and 4, the proposed algorithm enhances the average \u0000waiting time's time complexity by 50% with datasets containing random and \u0000outlier tasks.","PeriodicalId":372911,"journal":{"name":"Journal of Engineering and Technological Sciences - JOEATS","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127578393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
