无线移动环境中基于移动Agent的实时构件组装机制研究

由于无线网络较窄、昂贵的带宽，及移动设备自身有限的硬件能力，在无线移动环境中进行实时构件组装调用时面临着更多的技术挑战，需要一种高效、可靠的机制给予支持。本文提出一种基于移动Agent的无线网络环境构件组装调用机制。该机制利用移动Agent作为移动客户端与构件服务器之间交互的中介，提供了灵活、可配置的组装结构，从而有效避免移动客户端不必要的访问操作，节省了移动客户端的无线网络连接开销，与其他机制相比有着较高的执行效率；同时该机制可有效支持移动客户端发生故障后的状态恢复，从而确保运行过程的可靠性。最后本文通过实验分析了MAWA机制的可靠性与高效性。

Research on Real-time Component Assembly Based on Mobile Agents in Mobile Wireless Environments

Because of the limited capability of mobile devices and lower bandwidth of wireless network, real-time com- ponent assembly in mobile wireless environments suffers more challenges and it needs an efficient and reliable mecha- nism to support. This paper presents a flexible and configurable mechanism, which uses mobile agents as brokers of mobile unit (MU) to communicate with component server, thus to reduce the unnecessary wireless communication costs of mobile client. It can also facilitate MU recovery back when suffering a failure to increase the reliability of the whole assembly process. Compared with other mechanisms through performance analysis, our mechanism shows its ef- ficiency and reliability.
