The Study of PSTN P2P Protocol in Distributed Multi-Database System in Intelligent Materials System

In intelligence materials system, sensor nodes may typically scattered around the targeted surveillance area. Therefore, all nodes within such network are responsible for collect and route data from sensors to receivers. Along with the development of intelligent materials databases, communication speed and efficiency may strongly affect the performance of distributed multi-database system. This paper firstly introduces a p2p distributed multi-database system architecture and its characteristics, moreover explains the node communication mechanism. Secondly, it proposes a protocol with its 4-layer structure and respectively explains the layer design ideas and functionalities. Finally, by analyzing the transmission efficiency and speed, the paper proposes the practicability and validity of protocol.
