Designing wireless sensor networks should meet appropriate parameters such as quality of service (QoS) defined by different users. The variable physical conditions of the environment, processing and transmission power limitations and limited communication capabilities are the most important obstacles that influence QoS parameters such as throughput, delay, reliability and network lifetime. The ...

A quality-of-service (QoS) management framework for a complex distributed real-time system must be able to accommodate diierent dimensions and measures of quality, aaect QoS tradeoos across applications, and monitor and maintain the overall quality of the service produced by them as a whole. This paper describes a QoS model and an end-to-end QoS management architecture designed to meet these ob...

Quality of Service (QoS) analysis and prediction for Web service compositions is an important and challenging issue in distributed computing. In existing work, QoS for service compositions is either calculated based on constant QoS values or simulated based on probabilistic QoS distributions of component services. Simulation method is time consuming and can not be used in real-time applications...

Quality of Services (QoS) management in compositions of services requires careful consideration of QoS characteristics of the services and effective QoS management in their execution. This paper describes an approach to implementation of QoS management in compositions of Web services in the context of Computational Quality Attributes and Service Level Agreements. Building on prior research work...

Streaming media applications is currently limited by high bandwidth requirements. It is a challenging problem to provide the required quality of service (QoS) for the efficient transmission of video data under the varying network conditions such as the time-varying packet loss and fluctuating bandwidth. On Internet the most important part for streaming media transmission application is QoS cont...

This is a survey paper on IP QoS over ATM. It describes the need for QoS in the Internet and the mechanisms of QoS provisioning in IP. ATM is briefly described with a view to highlight its inherent support for QoS. Then, mechanisms of providing IP QoS over an ATM network are considered. Also issues that arise in implementing the various IP QoS over ATM is considered. See Also: Quality Of Servic...

A deep comprehension of Quality of Service (QoS) is essential before attempting to understand any QoS management model. Quality of service may be thought, at first sight, a simple and obvious notion. Nonetheless, an inspection in related literature emerges the complexity of the subject. This chapter analyzes the full significance of quality of service concept. First, a review of the most releva...
