RadiaLE

RadiaLE is a benchmarking testbed that allows the performance evaluation of Link Quality Estimators (LQEs) by analyzing their statistical properties, independently of any external factor, such as collisions and routing. These statistical properties demonstrate the behavior of the LQEs both in terms of Reliability and Stability.

• Reliability refers to the ability of the LQE to correctly characterize the link state.
• Stability refers to the ability to resist to transient (short-term) variations (also called fluctuations) in link quality.

RadiaLE includes (i.) hardware components that represent the WSN under test and (ii.) a software tool for the set up and control of the experiments and also for analyzing the collected data, allowing for LQEs evaluation.

RadiaLE hardware architecture involves a set of TelosB motes, connected to a control station (PC) via a USB tree, for controlling and collecting data from the motes without interfering with the wireless communications.
The experimentation is ensured by RadiaLE software tool. It contains two independent applications: ExpCtrApp and DataAnlApp.

• ExpCtrApp: Experiment Control Java application. It allows motes programming/control, network configuration and data logging into a MySQL database.
• DataAnlApp: Data analysis Matlab application. It processes the collected data to provide two main functionalities: links characterization and LQEs perfomence evaluation.
