Increasing the performance of wireless mesh networks is an important topic, which has been addressed in both theory and practice. Indeed, the availability of low-cost hardware justifies hands-on investigations and comparisons of protocols used in mesh networks deployments. In this work, we describe a real-life testbed that we have developed in order to investigate traffic routing in multihop, multiradio meshed networks with mobile users. We consider an environment where a user connects to different infrastructure mesh nodes as it moves, and we compare the performance of state-of-the-art routing protocols, namely, OLSR, OLSR-ETX, B.A.T.M.A.N and our modified version of this protocol, called sw-B.A.T.M.A.N. Our experimental measurements show that sw-B.A.T.M.A.N outperforms the other protocols, ensuring a seamless connectivity in presence of MPEG video streaming, with and without background traffic.
