With the evolution of QoS-capable third generation (3G) wireless networks, the wireless community has been increasingly looking for a framework that can provide an effective, network independent, end-to-end Quality of Service (QoS) control. In this article, we first construct such a framework and then describe how dynamic SLA-based control can be used to achieve end-to-end QoS in a wired and wi...

abstract in recent decade, the research regarding wireless applications in e-health services has increased. simple communications, fast delivery of medical information, reducing treatment cost and reducing the medical workers error rate, are the main benefits of using wireless technologies in e-health applications. but on the other hand using wireless technologies causes the electromagnetic int...

How do different QoS (Quality of Service) mechanisms affect the resource and quality allocations over the interconnection of the future Internet? What will be the consequences on the economics of interconnection and its settlements? These are important questions that arise with the evolution of the Internet as a network of QoS networks that support a variety of performance requirements. The con...

In the context of heterogeneous wireless networks, or 4G networks, a number of problems are yet to be solved. One of these problems is the lack of Layer 2 QoS provisioning in heterogeneous networks, mainly due to the non-uniform nature of the QoS models and service interfaces among different wireless technologies. In addition, 4G access networks may include Access Points with no dedicated chann...

During the last few years, Value Added Web Services (VAWS) are increasingly becoming a hot issue in both research and industry. With the abundance of VAWS providers, Quality of Service (QoS) is a key factor to allow potential clients to differentiate between providers. In this paper, we propose a new architecture, called VAQoS, for managing and assuring QoS provision for VAWS. This architecture...

Service composition is popular for composing a set of existing services to provide complex services. With the increasing number of services deployed in cloud computing environments, many service providers have started to offer candidate services with equivalent functionality but different Quality of Service (QoS) levels. Therefore, QoS-aware service composition has drawn extensive attention. Mo...

Quality of Service (QoS) in data networks has been debated for atleast 35 years. Despite two decades of vigorous research and standards activity, QoS schemes have floundered. Research in QoS mechanisms assumes the existence of a large market for QoS-sensitive applications that will justify the expense of enabling QoS in the network. However, the lack of need for hard guarantees by both the cust...

Distributed Real-time and embedded (DRE) systems require multiple, simultaneous quality of service (QoS) properties, such as predictability, reliability and security for their correct operation. With increasing focus on composing DRE systems from components, it becomes necessary for system designers to ensure that the system composition and its QoS configurations are functionally and systemical...

Quality of service (QoS) support in Mobile Ad-hoc NETworks (MANETs) is a challenging task. Most of the proposals in the literature only address certain aspects of the QoS support, e.g., QoS routing, QoS medium access control (MAC) and resource reservation. However, none of them proposes a QoS model for MANETs. Meanwhile, two QoS models have been proposed for the Internet, viz., the Integrated S...
