RealMedia Streaming Performance on an IEEE 802.11b Wireless LAN

چکیده
This paper presents experimental measurements of RealMedia audio/video streaming applications on an IEEE 802.11b wireless LAN. Empirical traffic measurements collected using a wireless network analyzer are used to characterize RealMedia streaming workloads, and to assess their impacts on wireless network performance. In addition, we study the relationship between the wireless channel error rate and the user-perceived quality of RealMedia streaming applications. We find that the RealMedia application provides relatively robust audio and video streaming quality in all but the poorest of wireless LAN conditions. Finally, competing TCP/IP Internet traffic is found to have relatively little impact on the quality of UDP-based RealMedia streaming sessions.

متن کاملEnhanced Protection Mechanism for Wireless LAN to Reduce Protocol Overhead
The Wireless LANs (WLAN) have become more popular and commonly used these days. WLAN links many devices using some wireless methods like OFDM, Spread Spectrum etc. There are several IEEE Standards exists for Wireless LAN, among them IEEE 802.11b and IEEE 802.11g are most popular types of IEEE 802.11. These two standards are “Wi-Fi” certified and operate at 2.4GHz band. The 802.11g supports high...
متن کاملMedia Streaming Performance in a Portable Wireless Classroom Network
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 streaming 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...
