The service-oriented paradigm is emerging as a new approach to heterogeneous distributed software systems composed of services accessed locally or remotely by middleware technology. How to select the optimal composited service from a set of functionally equivalent services with different quality of service (QoS) attributes has become an active focus of research in the service community. However...
Web Services are the interoperable and loosely coupled components for simplifying business processes over the web and are popular model of distributed computing now a days. There are a very few datasets available regarding Quality of Service (QoS) for web services since web services datasets are difficult to create. The reason being that it requires more effort to collect service information fr...
In order to guarantee deadlines of real-time messages, it is necessary to construct connections or realtime channels before the actual transmission of the messages. An increasing number of distributed realtime systems that are related to multimedia and command and control systems require flexible network resource management. Those schemes proposed before couldn’t accept channel construction req...
Quality of Service (QoS) is defined as a set of perceivable attributes expressed in a user-friendly language with parameters that may be subjective or objective. Objective parameters are those related to a particular service and are measurable and verifiable. Subjective parameters are those based on the opinions of the end-users. We believe that quality of service should become an integral part...
Energy/QoS provisioning is a challenging task for video applications in power-constrained mobile embedded systems. Many error-resilient video encodings allow us to exploit errors and generate a range of acceptable tradeoff spaces by controlling the amount of errors in the system. This expanded tradeoff space allows system designers to comparatively evaluate different operating points with varyi...
With the rapid development of communication technology and mobile Internet, selecting from mass Location-based Services to meet the needs for different users becomes the research hot spot under mobile Internet environment. First of all, it starts from QoS constraints as well as user preferences in this paper, and then describes a mobile service selection framework based on QoS constraints and u...
The increasing popularity of employing web services for distributed systems contributes to the significance of service discovery. However, duplicated and similar functional features existing among services require service consumers to include additional aspects to evaluate the services. Generally, the service consumers would have different view on the quality of service (QoS) of service attribu...
