Enhanced TOSSIM for Sensor Network Simulations

This paper discusses the enhancements made to TOSSIM, a simulation environment for sensor networks, focusing on key goals such as reducing simulation time and improving functionality. It covers various topics including scalability, fidelity, and hardware emulation. We explore multiple applications, heterogeneous networks, and mobility models, addressing common issues like timer overflow. By comparing TOSSIM with NS-2 and implementing strategies to locate bottlenecks, this work aims to make sensor network simulations more efficient and effective, fostering further research and development in the field.
