| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 92 === Peer-to-Peer (P2P) communication has attracted peoples’ attention due to its resource sharing capabilities, such as the exchanging of information and content files and sharing processing cycles, cache space, and disk storage. Moreover, P2P system can be easily implemented with low cost. Therefore, the traditional client/server architecture has been gradually replaced by P2P structure.
The collaborated computing system for load sharing takes the advantages of P2P system. Furthermore, the disadvantages in P2P system, security, awareness, performance efficiency, and compatibility, have been conquered by the collaborated computing system by implementing the system using Java Servlet. Through this mechanism, a large computing task can be completed with improved efficiency.
In this thesis, the collaborated computing system was utilized based on the case of analyzing the robustness of digital watermark by filter bank selection. As the result of this case, the performance can be improved in the aspect of speedup, efficiency, process time and reliability.
