Ferry-based networks provide a means of bringing extremely low-cost Internet access to remote rural areas, where conventional access technologies, e.g., dial-up, DSL and CDMA, are currently economically infeasible. We present an architecture for ferry-based networks and identify downlink scheduling as a difficult open problem. We argue that opportunistic scheduling policies that take ferry sche...

In this paper analyzes various scheduling algorithms applied to multi-media streaming system for providing real-time service in Internet and proposed a scheduling algorithm that can meet the QoS requirements of delay-sensitive traffic and loss-sensitive traffic for specific services. First, the concept of QoS drafted from the recommendation of ITU-T is defined and the requirements for packet mu...

In this paper, we provide a Genetic Algorithm (GA) based approach for change management in Enterprise IT systems which minimizes change delay and improves change capacity. Change management evolves the implementation of change queues on the set of applications which are running on one or more servers. To implement these changes there are some constraints involved: atomic nature of changes; when...

For wireless data traffic, energy efficiency can be improved by adapting the transmission power and rate over time based on the offered traffic as well as any channel state information. In this context, a variety of transmission scheduling approaches have been studied including [1, 2, 3]. These approaches attempt to manage the fundamental trade-off between packet delay and transmission power or...

The dynamic instruction scheduling logic (the issue queue and the associated control logic) forms the core of an out-of-order microprocessor. Traditional scheduling mechanisms, based on tag broadcasts and associative tag matching logic within the issue queue are limited by high power consumption, large access delay and poor scalability. To address these inefficiencies, researchers have proposed...

The Worldwide Interoperability for Microwave Access (WiMAX) is the IEEE 802.16 standard. Scheduling in WiMAX become one of the most challenging issues, since it is responsible for distributing available resources among users to meet the Quality of Service(QOS) criteria such as delay, delay jitter, fairness and throughput requirements. However, no specific scheduling mechanism has been defined t...

Recent researches present that packet-mode scheduling may provide overall performance advantages over cell-mode scheduling in input queueing switches. But one significant drawback of existing packet-mode schedulers is that they tend to result in longer waiting time of short packets, whose delay is critical to the performance of IP networks. To mitigate the problem, this paper proposes a simple ...

In Mobile Ad hoc Networks (MANETs), achieving fairness and increasing channel utilization are the important design goals of scheduling. However, these two goals contradict with each other. In this paper, a fair-scheduling technique for inelastic traffic flows in MANET is proposed. The network traffic is differentiated into two categories as elastic and inelastic flows. In this technique, data p...

For utilizing distributed resources in optical grid environment advanced reservations play a very crucial role. For applications like the co-allocation of distributed resources and deadline driven applications advance reservations are essential. Also for enhancing capabilities of resource brokers advance reservations play a major role. The objective is to determine a scheduling algorithm that m...

Providing packet-level quality of service (QoS) is critical to support both rate-sensitive and delay-sensitive applications in the bandwidth-constrained, shared-channel, multihop wireless networks. Packet scheduling has been a very popular paradigm to ensure minimum throughput and bounded delay access for packet flows. This work describes a packet scheduling approach to QoS provisioning in mult...
