Query processing in mobile P2P system based on active database
基于主动数据库的移动P2P查询处理

In this paper, a system model of mobile agent construction and management was presented. It uses ECA rules of Active Database to define the logic structure of the agent and uses the trigger mechanism of Active Database to manage and execute the agent. By this means not only the architecture of the P2P system supporting instant and contiguous query is significantly simplified, but also the security and efficiency of information are guaranteed through the security mechanism of the Active Database. The architecture of a mobile P2P system node was firstly presented, followed by the structure, management and life cycle of the mobile agent and lastly an application instance was given.
