在传统分布式系统中,由于任务之间具有明确的依赖关系,所以有很多方法来实现任务的控制。但这些方法已经不适于移动Agent环境,其根本原因在于移动Agent之间不存在那种“自然”的依赖关系。文章提出了一种移动Agent的控制机制,它基于以AgentTracer为中心以Agent影子为辅助的Agent追踪方法,结合能量概念来实现移动Agent的控制,并说明这种方法是高效的。 In traditional distributed systems, there are many ways to achieve task control because of the explicit dependencies between tasks. However, these methods are not suitable for mobile Agent environment, the fundamental reason is that mobile agents do not exist between the kind of “natural” dependencies. This paper presents a control mechanism of Mobile Agent, which is based on the Agent tracking method with Agent Shadow as the center and the Agent control method based on AgentTranscenter. Combining with the concept of energy, the control of Mobile Agent is realized, and the method is efficient.
