Abstract: To understand and analyze the autonomous working mechanism of Wireless Sensor Network (WSN) that is independent of internal structure and practical implementation, the various working states and self-organization properties of WSN nodes were analyzed, and an Agent class meta-model for WSN nodes was built up. The proposed meta-model was based on the Agent BDI model, extended AUML Agent class diagram by adding Mental, Role and Protocol model elements that met WSN characteristics to describe the static structures of WSN nodes. The case study shows that, in combination with node working states, the Agent class meta-model provides the good fundamentals of visual modeling and analysis tools for WSN node architecture research.

摘要： 为独立于内部结构和具体实现来理解和分析无线传感器网络节点的自治工作机制，分析了无线传感器网络节点的各种工作状态和自组织特性，建立了一种面向无线传感器网络节点的Agent类元模型。该元模型在Agent BDI模型基础上，扩展AUML Agent类图，引入符合无线传感器网络特性的Mental、Role和Protocol等模型元素来描述无线传感器网络节点的静态结构。实例分析表明，结合节点工作状态，Agent类元模型为无线传感器网络节点体系的研究提供了良好的可视化建模基础和分析工具。
