Abstract

Wireless networks are becoming more popular in all types of environments from home office, to business infrastructure, to mobile computing. As more of these networks flourish, so does the attraction for hackers. The thesis examines the bandwidth of wireless networks and the effects of intrusions in three different scenarios. First, it looks at a wireless network that is connected to a wired infrastructure. Next, the thesis examines a wireless ad hoc network and how bandwidth plays a valuable part in the communication with neighboring nodes. And finally, the thesis attempts to simulate a wireless network by using a bandwidth configuration method on a dynamic switch.

The thesis looks at the three different scenarios in two ways. First, it examines the bandwidth utilization without any intrusion attempts. This was done in order to obtain a baseline for analysis. Secondly, it introduces intrusions into the scenarios and examines the effects. Data is collected for both types of scenarios and compared to determine if there is a noticeable effect on the utilized bandwidth.
