| Fairness and protection are two important properties required to support Quality-ofService (QoS). In this paper, we present WGPS (Wireless General Processor Sharing) and PWGPS (Packetized WGPS) schedulers to provide fairness and protection in wireless packet networks. Since our schedulers pre-allocate bandwidth for compensating ows which su ered bursty and location-dependent channel errors an...

Supporting application QoS in wireless environment remains a challenging task due to the inherent constraints of wireless interfaces (resource scarcity, signal quality, etc.). While current standards offer relative QoS through service class differentiation, assured QoS is still a critical requirement for supporting multimedia and real-time applications. In consideration for fairness and bandwid...

We consider connection-level models of resource allocation in a simple symmetric three-link network, where files arrive into the network according to a Poisson process and the size of each file is exponentially distributed. For the simple network under consideration, we derive an optimal resource allocation policy which minimizes the steady-state expected number of files in the network. Using t...

We will present a new resource allocation strategy that allows efficient mapping of variable-rate IPstreams onto shared cellular links, while minimizing the overall bandwidth consumption and still meeting the individual quality-of-service constraints. It is based on the general principle of Class-Based Queuing, with several modifications to adapt it to the specific characteristics of wireless l...

| In heterogeneous environments with performance variations present, multiple applications compete and share a limited amount of system resources, and su er from variations in resource availability. These complex applications are desired to adapt themselves and to adjust their resource demands dynamically. On one hand, current adaptation mechanisms built within an application cannot preserve gl...

The Manhattan Street Network (MSN) with the Clockwork Routing scheme has been proposed as a particularly suitable candidate for use in optical networks. However, without any medium access control (MAC), the success of the MSN with Clockwork Routing in optical networks would be inhibited by the destination-release protocol, since the protocol provides no guarantee of fair access or bounded traff...

Federation of Cloud services is notably landing interests from both Cloud providers and consumers. Cloud providers nowadays are required to form federations to remain competitive, and sustain their market share. Cloud consumers however seek optimized services from Clouds federation. They strive to maximize their satisfaction level, which is often measured by Quality of Service (QoS). Federation...

In this paper we analytically propose an alternative approach to achieve better fairness in scheduling mechanisms which could provide better quality of service particularly for real time application. Our proposal oppose the allocation of the bandwidth which adopted by all previous scheduling mechanism. It rather adopt the opposition approach be proposing the notion of Maxmin-charge which fairly...

Wireless LANs have achieved a tremendous amount of growth in recent years. Among various wireless LAN technologies, the IEEE 802.11b based wireless LAN technology can be cited as the most prominent technology today. Despite being widely deployed, 802.11b cannot be termed as a well matured technology. Although 802.11b is adequate for basic connectivity issues and packet switching, It is evident ...

This paper proposes a fair and efficient QoS scheduling scheme for IEEE 802.16 BWA systems that satisfies both throughput and delay guarantee to various real and non-real time applications. The proposed QoS scheduling scheme is compared with an existing QoS scheduling scheme proposed in literature in recent past. Simulation results show that the proposed scheduling scheme can provide a tight Qo...
