Response time is one of the characteristics of scheduler, happens to be a prominent attribute of any CPU scheduling algorithm. The proposed New Multi Level Feedback Queue [NMLFQ] Scheduler is compared with dynamic, real time, Dependent Activity Scheduling Algorithm (DASA) and Locke’s Best Effort Scheduling Algorithm (LBESA). We abbreviated beneficial result of NMLFQ scheduler in comparison with...

Today cloud computing technology is used everywhere. Cloud computing technology use increases due to its variety of facility. As cloud provide many facilities due to its vast area such that sharing of resources for different purposes scheduling become a necessary factor to discuss. In our paper different types of scheduling is applied in cloud computing network using servers on which load is ba...

This paper aims to develop a multi-objective model for scheduling cargo trains faced by the costs of tardiness and earliness, time limitations, queue priority and limited station lines. Based upon the Islamic Republic of Iran Railway Corporation (IRIRC) regulations, passenger trains enjoy priority over other trains for departure. Therefore, the timetable of cargo trains must be determined based...

With the number increment of mobile computing equipment, the invalidation of equipment and broadcasting information because of wireless bandwidth, communication quality and too long scheduling queue that badly influence the system computing performance. Mobile cache is a good technology to solute this difficult problem. Considering the priority problem of broadcasting queue generated by data in...

The IEEE 802.16j standard defines Mobile Multi-hop Relay Wireless Cellular Networks. Introduction of Relays in WiMAX networks pose new challenges along with the advantages of High Throughput and Improved Coverage Area. Thus Scheduling plays a crucial role in Mobile Multi-hop Relay(MMR) Wireless Networks. The Queue aware scheduling algorithm [1] maximizes the throughput by considering Queues at ...

This paper describes a novel cost-driven disk scheduling algorithm for environments consisting of multi-priority requests. An example application is a video-on-demand system that provides high and low quality services, termed priority 2 and 1, respectively. Customers ordering a high quality (priority 2) service pay a higher fee and are assigned a higher priority by the underlying system. Our pr...

CPU scheduling is the basis of multi programmed operating system. The idea of multiprogramming is relatively simple, if a process (job) is waiting for an I/O request, then CPU switches from one job to another job so that CPU is always busy and computer becomes more productive. Scheduling is a fundamental operating system function, almost all computer resources are scheduled before use. The CPU ...

Ethernet passive optical networks (EPONs) are being designed to deliver different quality of service (QoS) to carry heterogeneous traffic of end users. For this purpose, hierarchical scheduling is needed for up...

Real time and non-real-time data packets are the two types of scheduling packets which is used at sensor nodes with resource constraints in WSN of importance to reduce sensors energy and end-to-end delays. Existing First Come First Served, starvation of high priority real-time data packets due to the transmission of a large data packet in nonpreemptive priority scheduling, starvation of nonreal...

Differentiated Services (DiffServ) is a promising architecture for the next generation Internet due to its highly flexible, scalable and interoperable design. In DiffServ, scheduling disciplines play an important role in achieving service differentiation. In this paper, we extend the average delay analysis of the Probabilistic Priority (PP) scheduling discipline first proposed in [8] to the mul...
