A Large-Scale Testbed for Reproducible Ad Hoc Protocol Evaluations

Free registration required

Executive Summary

The authors have built an Ad hoc Protocol Evaluation testbed (APE) in order to perform large-scale, reproducible experiments. APE aims at assessing several different routing protocols in a real-world environment instead of by simulation. They present the APE testbed architecture and report on initial experiments with up to 37 physical nodes that show the reproducibility and scalability of the approach. Several scenario scripts have been written that include strict choreographic instructions to the testers who walk around with ORiNOCO equipped laptops. They introduce a mobility metric called Virtual Mobility that they use to compare different testruns. This metric is based on the measured signal quality instead of the geometric distance between nodes, hence it reflects how a routing protocol actually perceives the network's dynamics.
