SmartSim: Graphical Sensor Network Simulation Based on TinyOS and Tossim

Obtaining hundreds of sensor nodes to experiment new algorithms on Wireless Sensor Network (WSN) in real testbed is costly and time consuming. Simulation environment can reduce these costs though it may not produce exactly same results as real testbeds. There is many kind of simulations available for WSN such as Cooja and Tossim. None of these simulation environments provides an all-in-one solution to help researchers design topologies, running the network step by step and giving extensive reports of generation environment. In this paper a new simulation environment, SmartSim, has been developed to provide an useful all-in-one solution. It has new, unique features such as detailed graphical presentation of topology, ability to proceed through network events either forward or backward and a comprehensive power usage report generation. SmartSim eases the algorithm implementation in TinyOS based WSN, provides troubleshooting tools and linear and non-linear energy usage of the network.
