Existing ad hoc system design methods for Wireless Sensor Networks (WSNs) suffer from lack of reusability. In addition, the interactions between the continuous-time physical environments and WSNs have not been well studied. In this paper, we propose a model-based systems design (MBSD) framework for WSNs, which is a systematic methodology applying systems engineering principles to enhance model reusability and collaborations among multiple modeling domains. Firstly, we describe a hierarchy of

Based on the MBSD framework, we introduce a system design flow to compose both continuoustime and event-triggered modules to develop applications with support for performance study by simulations. Next, we briefly describe the main modules for physical platforms, the Media Access Control (MAC) layer, wireless channels and physical environments, which are developed using the Systems Modeling Language (SysML), Simulink and Modelica. Finally, we use a building thermal control system as the case study to demonstrate the composability, reusability and flexibility of the proposed MBSD framework.
