Real-world testbed

Definition

A real-world testbed is an experimental platform designed to evaluate the performance and functionality of wireless sensor networks in actual operational environments rather than in controlled laboratory settings. These testbeds provide crucial insights by simulating real-life conditions, enabling researchers and engineers to assess how their systems interact with various physical factors and user behaviors, ultimately helping to validate theoretical models and improve network designs.
