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.
