This paper presents empirical measurements of wireless media streaming traffic in an IEEE 802.11b wireless ad hoc network. The results show that the IEEE 802.11b WLAN can support up to 8 clients with good media stream ing quality, with each client receiving a separate 400 kbps video stream and 128 kbps audio stream. With 9 clients, the WLAN is overloaded, and performance degrades for all clients. Finally, we demonstrate a "bad apple" phe nomenon in wireless ad hoc networks, wherein a single client with poor wireless connectivity disrupts the media streaming quality for all clients sharing the WLAN.
