To improve the ability of agent for handling emotions, a new architecture for emotion agent is presented, based on the traditional BDI agent model and the rough set theory. By a new emotional reasoning algorithm based on rough set, the architecture performs emotion reasoning and implements the emotion treatment. An emotional agent grid based on this architecture has been realized, experiment results show that it is efficient to transact simple emotions by emotional agents. 相似文献

E-commerce systems for construction material procurement are becoming increasingly important in Hong Kong. These E-commerce systems are non-interoperable and create problems for the buyers who use these systems to purchase construction materials. This paper presents the mobile agent-based approach and Web services-based approach for enabling interoperation of these systems in the E-Union environment. 相似文献

To improve the scalability of RMON-based network management, the concept of Mobile RMON Agent (MRA) was presented by combining the mobile agent technology with RMON. Then an MRA-based Network Management System (MRANMS) was designed and implemented. RMON functions were achieved by programming the mobile agent to make it capture and analyze packets locally. The experimental result on the Grasshopper platform indicates that MRA as a mobile agent can migrate to another subnet and calculate a RMON MIB value and TrafficMatrix in a subnet with 29 hosts. Furthermore, the behavior of MRA can be customized to achieve new RMON functions, such as the statistics of hostTable in RMON MIB. It can be concluded that MRANMS is based on the mode of distribution, and besides the compatibility with standard RMON, the system possesses scalability of management function. 相似文献

从系统整体安全的角度,提出一种面向大规模网络应用的移动主体系统安全机制方案。该方案采用基于混合加密的双向认证技术解决移动主体系统的局部安全问题,通过各级移动主体安全管理平台完成密钥的分配与管理,并对移动主体的迁移进行合理的任务分配与调度,通过任务传递模式解决移动主体的跨网段安全迁移问题,这些措施较为全面的解决了当前移动主体系统的整体安全问题。而且由于采用层次化的系统结构和管理模式,使得该方案非常适合当前面向大规模网络的应用开发。 相似文献
