基于移动agent的异构网络PBD任务库搜索技术研究

Research of Mobile Agent-based PBD Task Library Searching Technology in Heterogeneous Network

从PBD可以扩展为基于异构网络的DPBD模型,使得网络中的机器可以共享任务库因而达到无需网络中的每台机器都安装完整的PBD系统的目的,而共享的任务库必然会导致搜索问题,普通的搜索技术很难达到DPBD任务库的搜索,而使用移动agent则可以提高DPBD包装器的搜索效率,同时可以大大减少网络负担。而且在移动agent内部增加安全机制,可以独立于开发平台增加搜索的可靠性。

PBD system can be expanded to DPBD model in order to enhance the reusability of the PBD system.We introduce mobile agent-based searching technology into DPBD model to help achieving this goal.Mobile agent-based searching technology not only can enhance the wrapper searching effect,but also can reduce the communication burden of the network.We invite the effective security mechanism into the mobile agent to improve the searching reliability which can be independent of the agent platform.
