11.4 Testbeds and experimental platforms

Wireless sensor network testbeds are crucial for experimenting with real-world WSN applications. These platforms, like FIT IoT-LAB and TWIST, offer large-scale environments with hundreds of sensor nodes for researchers to test their ideas.

Testbeds provide remote access, realistic conditions, and data collection tools. This allows researchers to deploy and evaluate WSN protocols and applications in practical scenarios, leading to more robust and reliable sensor network solutions.
