Emulation testbed

Definition

An emulation testbed is a simulation environment that mimics the behavior of a real-world system, enabling researchers to test and validate the performance of various protocols and applications in a controlled setting. This setup allows for experimentation with different network configurations, sensor deployments, and communication strategies without the risks and costs associated with physical implementations. Emulation testbeds are particularly valuable in wireless sensor networks as they facilitate the study of complex interactions and scalability issues.
