Service Composition provides a flexible framework for new service construction by integrating atomic services developed independently. Algorithms are needed to select atomic service and service instances with various QoS levels according to some application-dependent performance requirements. Our objective of service selection is to maximize a QoS function under the end-to-end QoS constraints, as...
In this paper, a service routing method is proposed to support the pervasive E-commerce. To offer flexible routing control across multiple service domains, a customized route computation should be offered. In our method, a QoS-routing protocol is designed to select end-to-end paths that satisfy user requirements. And global QoS is guaranteed by the runtime QoS monitoring and dynamic adjustment.
In this paper, a E-Commerce service composition platform is proposed to support the pervasive E-commerce. The platform consists of an Orchestration Component and several Atomic Service Components. The platform is based on atomic reusable and sharable service components. And it employs efficient P2P interaction between two components. In our method, global QoS is guaranteed by the runtime QoS monitoring...
Mashups is an emerging technology that enables users to create a new application based on a composition of contents retrieved from external services or applications. Mashup Platform allows non-programmer end-users to mash-up information sources and services to meet their information needs. However, with the increasing number of services, information sources and complex operations like filtering and...
Service composition is becoming a hot research point in recent years, especially in distributed peer-to-peer (P2P) network. However, how to guarantee the high-quality composition service performance becomes the key technology and difficulty in P2P network, which draws lots of attention in computer research field. According to the characteristics of distributed network, an adaptive service composition...
With the popularity of Web2.0, web has become to be a application programming platform where third parties can create new applications (mash-ups) mixing the functionality offered by others. Now this trend has extended to the domain of mobile networks. The combination of mashup and mobile networks would make the mashup more powerful and provide additional user value. This paper explores how to realize...

Next generation networks (NGN) are the basis of converged IT and telecom services and OSS is a crucial, mission critical area in the Telecommunications domain, in particular in a period of economic recession and heavy cost savings. There is a trend to adopt Service Oriented Architecture (SOA) to rationalize OSS infrastructure in NGN. In this Paper, we present an innovative OSS solution based on SOA...
