Distributed computing power service coordination based on peer-to-peer grids architecture

As computational speed, storage capacity, and communication technologies steadily progress to the advanced levels, many business employments have utilized these improvements to aggregate distributed resources in various enterprise collaborating functionalities. Recently, grid computing has been identified as a critical technology by industry for enterprise computing and business-to-business computing. The concept of peer-to-peer (P2P) network is also evolving to an expanded usage in distributed networks for sharing the resources like the content files or real-time data for enterprise applications. Therefore, it is natural to include the grids and P2P to support environments that have features of both limiting case. In this paper, a new computing design - NaradaBrokering based Computing Power Services (NB-CPS) - has been applied to utilize the P2P grid to integrate the computational grids, distributed objects, P2P networks under the hybrid environment. In this study, the approach has been applied to analyze the robustness of digital watermark by filter bank selection and the performance can be improved in the aspect of speedup, stability and processing time. NB-CPS is not only suitable for executing computing works which are able to run in batches, but also be able to solve current issues in Web Services based Computing Power Service (WS-CPS) such as system resilience, fault tolerance, efficiency of job scheduling and the instability in congested network environment.
