Abstract: It presents the application of Architecture Analysis and Design Language (AADL) for modeling of wireless sensor networks, and introduces a careful analysis of wireless temperature sensor. Firstly, the structure language AADL is introduced along with its advantages of modeling in embedded systems. Secondly, features and key technologies of wireless sensor networks are provided. Based on AADL, structure and function of the wireless temperature sensor are introduced, explaining the internal structure and the working principle of the temperature sensor, which plays an important role in improvement and extension in practical applications and helps a further applied to the sensor networks.

Key words: Architecture analysis and design language, Wireless sensor network, Temperature sensor, Embedded system
