Multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. In this paper, a new clustering based multi path routingprotocol namely ECRR (Energy efficient Cluster based Routing algorithm for improving Reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required QoS ...

This paper shows a detailed overview of QoS routing metrics, resources, and factors which are affecting performance of QoS routing protocols. The relative strength, weakness, and applicability of existing QoS routing protocols are also studied and compared. QoS routing protocols are classified according to the QoS metrics.

The infrastructureless nature of mobile ad hoc networks poses an extreme challenge for the design of conventional and Quality of Service (QoS) routing protocols. To the best of our knowledge, current QoS routing protocols have primarily been designed to meet QoS metric(s) without concentrating on the robustness of the proposed routing solution. This paper proposes a QoS virtual backbone (QoS-VB...

This paper addresses the problem of inter-domain QoS routing with Service Level Agreements (SLA) for data transport between peering domains, using virtual-trunk type aggregates. The problem is formally stated and formulated in Integer Linear Programming. As a practical solution, we define the QoS INFO extension to the BGP routing protocol, conveying three different QoS metrics (light load delay...

Middleware systems have emerged in recent years to support applications in heterogenous and ubiquitous computing environments. Specifically, future middleware platforms are expected to provide Quality-of-Service (QoS) support, which is required by a new generation of QoS-sensitive applications such as media streaming and e-commerce. This article presents four key aspects of a QoS-aware middlewa...

We address the issue of how to provide basic Quality of Service (QoS) in optical burst-switched WDM networks with limited fiber delay lines (FDLs). Unlike existing buffer-based QoS schemes, the novel offsettime-based QoS scheme we study in this paper does not mandate any buffer for traffic isolation, but nevertheless can take advantage of FDLs to improve QoS. This makes the proposed QoS scheme ...

Several Quality of Service (QoS) architectures and mechanisms have been proposed by standardisation bodies. However, those proposals were not always aligned with the spirit of IP networks. Furthermore, most research activities have focused to date on supporting QoS only within a single administrative domain. In this paper, we demonstrate that it is possible to provision QoS-enabled services tha...

Developers of QoS (Quality of Service) applications need component frameworks that support QoS to improve their development process. We propose to use the component infrastructure level for the integration of QoS facilities to avoid the problems of QoS infrastructures dependencies, and to simplify the development process of applications. This paper introduces our model of QoSaware component, an...

Incompatibility of different QoS (Quality of Service) mechanisms and heterogeneity of different vendors’ network devices are the major obstacles for providing end-to-end QoS in IP network. Inspired by Java, we propose an end-to-end QoS solution in this paper, i.e. QoSJava, which decouples QoS requirements from network details. By QoS Mechanisms Adapter and Device Driver, which act as “Java Virt...
