Resumo(s)
Link quality estimation is a fundamental building block for the design of several
different mechanisms and protocols in wireless sensor networks (WSN). A thorough
experimental evaluation of link quality estimators (LQEs) is thus mandatory.
Several WSN experimental testbeds have been designed ([1–4]) but only [3]
and [2] targeted link quality measurements. However, these were exploited for
analyzing low-power links characteristics rather than the performance of LQEs.
Despite its importance, the experimental performance evaluation of LQEs
remains an open problem, mainly due to the difficulty to provide a quantitative
evaluation of their accuracy. This motivated us to build a benchmarking testbed
for LQE - RadiaLE, which we present here as a demo. It 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.
