This paper studies the user-level and network-level performance for a mobile client browsing the Web using a wireless Personal Digital Assistant (PDA). A wireless network analyzer is used to collect traces of the TCP/IP network traffic generated to and from the wireless PDA. Multi-layer protocol analysis is used to assess the Web browsing performance achieved, and identify protocol performance problems. The analyses focus on server response time, document size, HTTP transfer time, TCP performance, and wireless channel quality. The analysis studies the multi-layer protocol interactions that arise when HTTP and TCP/IP operate over an IEEE 802.11b WLAN.
