With the growing expansion of web services resources on the internet, more and more users come to appreciate the difficulty of searching self-gratification information from the mass information. This paper analyzes functional attributes and un-functional attributes of Web service resources, builds the mapping relationship between FQoS and QoS, and defines the index system structure of FQoS (Fun...

Workflow management system, a technique that manages different types of processes/jobs gathered as a workflow, ensures that each task in the workflow is accomplished to proceed further. When the process happens between two parties, the client and the server, a binding agreement or contract is defined specifying the Quality of Service (QoS) metrics such as products/services to be delivered, the ...

In an open electronic service market, competing service providers offer services to clients who may choose freely among the service types and service providers. Before the service provision, a client needs to identify a particular server and negotiate a service contract that determines the contractual constraints for the service interactions. Part of the contract will be an agreement on the ser...

For distributed multimedia applications, especially highly interactive applications and those relying on the transfer of continuous media, it is essential that quality of service (QoS) is configurable, predictable and maintainable system-wide, including the distributed systems platform, operating system, end-system devices, communications subsystem and network. Although researchers have address...

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...

In this paper, we assess Quality of Services (QoS) requirements in wireless sensor networks (WSNs).QOS is a key component of the IMS. The QoS for a particular session is determined by a number of factors, such as the maximum bandwidth that can be allocated to the user based on the user’s subscription or the current state of the network. The IMS allows operators to control the QoS a user gets, s...

In this work the Service abstraction is extended to support Quality of Service (QoS) attributes – and implemented in the Grid QoS Management (G-QoSM) framework. The framework supports three main functions: (1) providing mechanisms for establishing QoS guarantees via Service Level Agreements (SLAs), (2) enabling QoS management on allocated QoS-aware services, and (3) supporting discovery of serv...

In this paper, we extend the current approaches to service discovery in a service oriented computing environment, such as Web Services and Grid, by allowing service providers and consumers to express their promises and requirements for quality of service (QoS). More specifically, we allow service providers to advertise their services in an extended DAML-S that supports quality specifications, a...

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...
