The following topics are dealt with: information resource management and QoS; image processing and pattern recognition; wireless networking and information networks; distributed and multi-agent systems and data mining.
This paper describes the distributed resource management for QoS driven for CAD-Grid integrated system. In this work, system actualization mode, architecture and function module are discussed in building a distributed QoS driven for CAD-Grid system. An emphasis has been placed on making the tools interactive, in an effort to create a user friendly environment. The goal is to provide an efficient and...
An estimation suited for network VBR (Variable bit rate) service parameters in the ATM(asynchronous transfer mode) network In order to guarantee the quality of service in the ATM network effectively satisfied userpsilas request, this paper proposed a new kind of method to estimate the service parameters in the VBR ON/OFF source model. According to different service parameters, this method could satisfy...
In order to solve the problems that the process of the evolution is only in one step and the investment in network is so costly when the network in nowadays evolutes to NGN(Next Generation Networking), this paper has get a deep research about the soft switch, media gateway control protocol, access gateway and media server and such kind of technology and then submit a kind of design methodology, through...
Cognitive radio has been considered as a promising paradigm to achieve efficient spectrum usage by allowing the coexistence of the primary and secondary networks. One fundamental challenge is to ensure the quality of service (QoS) of the primary link while maximizing the transmission rate of the secondary links. In this paper, we investigate cooperation based spectrum access at the secondary networks...
Web services composition is a good way to construct complex Web software. However, Web services composition is prone to fail due to the unstable Web services execution. Thus, it is necessary to deal with the abstract hierarchical modeling of multi-partner business process. Therefore, this paper proposes a refinement method for failure compensation process of transaction mechanism, constructs failure...
Grid technology is popular in science and business computing environment, with workflow the flexibility and applicability of the grid system can be greatly enhanced. Cost-effective scheduling of grid workflow applications represented by DAG (directed acyclic graph)is an essential and complex problem. In general such problem is NP-hard. In this paper, a novel heuristics, DSL (deadline segment leveling)...
The real-time distributed computing environment and reusable software architecture are important factors that affect the fidelity of flight simulation. We accomplished a flight simulator based on DDS (data distribution service for real-time systems) middleware and structural software architecture and proved its high fidelity as a flight training device. According to the analysis of flight simulator's...
The distributed denial of service attacks have become more and more frequent and caused some fatal problems. Many researches have been done to detect and defend such attacks, however, many solutions are still in the phase of theoretical studies. Some of them may have certain practical value, but they have to reconstruct the existing network and the routing instruments with great cost. This paper proposes...
Semantic Web Service technology provides a strong support for automation software development based on Web service. By analyzing the existing description models and methods of semantic Web service, a Semantic Web Service Description Model (WSDM4S) and its formal description based on SHOIN+(D) are proposed, which attempt to offer an effective model for description, publication, discovery, composition,...
