Video to Go: The Effects of Mobility on Streaming Media in a CDMA2000 1xEV-DO Network

摘要

This paper experimentally examines the performance of streaming media applications over a CDMA2000 1xEV-DO network. The performance of streaming in a cellular network is tested across three different levels of mobility, two applications, and the two transport layer protocols, TCP and UDP. Findings of this study are that streaming applications are impacted more by sources of interference such as high-rise buildings than by increased velocity. Also, when the mobile client is stationary, high data rates and high video quality are consistently achieved. We also find that for the streaming applications considered, UDP streams outperform TCP streams, consistently achieving higher bandwidth.
