In The P2P Environment Task Graph-Based Optimization And Realization Of Perceptual Model

In modern society, the field of computers, many people together to complete the cross-cutting, interdisciplinary work (Computer Supported Cooperative Work, CSCW) means:"In the network environment, a group with by computer work together to accomplish a task." Nearly two years with the domestic information technology and scientific and technological development and improvement, CSCW research and application has been considerable progress. Knowledge to promote economic development model for its development has opened up a new situation. As CSCW in modern applications continue to expand, has become many scholars research. China’s experts in the field of CSCW research Professor Shi Meilin clear that computers supporting role for people’s production and life impact should not be underestimated, for improving production efficiency, improve people’s quality of life is of great significance. As time continues to advance, the computer technology will increasingly work together towards the direction of the computer.In this paper, P2P network computer collaborative awareness models have been studied in existing collaborative awareness model, based on the contents of perception through collaboration, collaborative awareness of the key technologies, such as perceptual model content analysis research, we propose a role-based task graph groups perceptual model, from the most basic level, the concept of relevant definitions of the model were analyzed, and the realization of the key technologies of the model:the role of task-level map construction, the role of the task hierarchical graph simplification, perceptual model of perception levels were focused research. The model by introducing atomic task relationships to build the role of task-level perceptual model diagram, on the role of the task hierarchy diagram in a simplified process, through the merger of atomic tasks and roles to make the task hierarchy diagram simplified role-based P2P networks environment with higher efficiency. Finally, based on our theoretical research papers, based on the design and implementation of a role-based task graph model of group awareness. Simulation results show that the model in the message feedback delay, conflict resolution latency, packet loss rate and other aspects of the information relative to the existing models have a more significant improvement. Using this model, developers can work together in the design and development of multiplayer system, quickly and easily achieve system-aware, which may lead to lower development effort and reduce development costs, improve development efficiency.
