A new interesting research area is the representation and analysis of the networked economy using Open Semantic Service Networks (OSSN). OSSN are represented using the service description language USDL to model nodes and using the service relationship model OSSR to model edges. Nonetheless, in their current form USDL and OSSR do not provide constructs to capture the dynamic behavior of service ...

We present an approach to the admission control and resource allocation problem in connection-oriented networks that o er multiple services to users. Users' preferences are summarized by means of their utility functions, and each user is allowed to request more than one type of service. Multiple types of resources are allocated at each link along the path of a connection. We assume that the rel...

As Grids are emerging as the next generation service-oriented computing platforms, they need to support Grid economy that helps in the management of supply and demand for resources and offers an economic incentive for Grid resource providers. To enable this Grid economy, a market-like Grid environment including an infrastructure that supports the publication of services and their discovery is n...

With the global development of knowledge economy, the knowledge requirement of farmers is more personalized and solution-oriented, so there is pressing needs to develop agricultural knowledge service. The paper analyzes characteristics of agricultural knowledge service, and summarizes typical cases of agricultural knowledge service development in China.

Management of applications in the new world of pervasive computing requires new mechanisms to be developed for admission control, QoS negotiation, allocation and scheduling. To solve such resourceallocation and QoS provisioning problems within pervasive and ubiquitous computational environments, distribution and decomposition of the computation are important. In this paper we present a QoS-base...
