performance issues in addition to those seen on wired networks
due to the characteristics of the radio communication channel
used by their Physical Layers (PHY). Understanding these issues
is a complex but necessary task given the importance of wireless
networks for the transfer of wide ranging packet steams
including video as well as traditional data. Simulators are not
accurate enough to allow all the intricacies of such
communication to be accurately understood, especially when
complex interactions between the protocols of different layers
occurs. The paper suggests cross layer measurement as a solution
to the problem of understanding and analysis of such complex
communication issues and proposes a framework in which
appropriate performance measurements can be made from a
WiFi network supporting a video streaming application. The
framework has been used to collect these measurements at the
PHY, MAC, Transport and Application layers. Analysis of the
collected measurements has allowed the effects of noise
interference at the PHY to be related to the perceived
performance at the Application Layer for a video streaming
application. This has allowed the effect of the SNR on the
download time of a video sequence to be studied.
