The use of WiFi in commercial and home networking is increasing at a very fast pace. This increase in popularity especially in unmanaged WiFi networks lead to increased interference among the devices and reduced goodput for the consumers. Most of the domestic users living in apartment buildings use their WiFi access points at default channel settings and transmit at highest power. Multiple devices being on the same channel and transmitting at highest power degrade the cumulative goodput of the network.

This thesis seeks to determine if in an unmanaged high density WiFi network, the cumulative goodput of a network can be increased by changing some RF parameters. The parameters we choose to tune are data rate, transmit power and carrier sensing. To answer this question a controlled test bed was designed which would provide repeatable and reliable results.

Finally, for each physical scnerio tesed we recommend a combination of data rate, transmit power and carrier sensing which would provide maximum cumulative goodput.
