Abstract

This paper presents a framework of simulation environment (SEMU) which allows developers to understand the behavior of applications or protocols for a wireless sensor network (WSN) before deploying real nodes in a physical environment. For eliminating the gap between simulation and real deployment, SEMU has supported fast real code emulation by dynamic binary translation technique. SEMU also models the controlled environment as virtual operating system (Virtual OS) to coordinate the interactions of large number of nodes. In addition, we have proposed a co-simulation model to enhance the accuracy of pure software simulation. Then a further synchronization problem will be addressed and resolved by the co-simulation model. The evaluation results show SEMU is really a fast scalable WSN simulator with real code emulation.
