无线移动环境中基于移动Agent的实时构件组装机制研究

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

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。

Because of the limited capability of mobile devices and lower bandwidth of wireless network, real-time component assembly in mobile wireless environments suffers more challenges and it needs an efficient and reliable mechanism to support. This paper presents a flexible and eonfigurable 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 efficiency and reliability.
