Performance evaluation and analysis of wireless networks is
essential because testbed experiments facilitate a better under-
standing of network and application characteristics. This un-
derstanding of performance, in turn, results in robust protocol
design. In this paper, we present an experimental study of mul-
timedia traffic performance in mesh networks. We evaluate the
performance of video and voice traffic through multi-hop wire-
less paths and study the capacity of the mesh network. We also
investigate the impact of different traffic and network charac-
teristics on application performance. The impact of different
wireless network interface card configurations is examined, fol-
lowed by our suggestions for how to improve performance. We
believe our study is beneficial for both wireless network capac-
