III - METHODOLOGY
Poll data at two minute intervals to determine inbound traffic, outbound traffic, and number of users at over 200 access points
Parse raw data using PERL scripts into a useable form
Analyze and graph data using excel.
Categorize AP’s in each building as residential, office, academic, and public areas to help identify differences between types of network usage.
I - OBJECTIVES
Collect traffic and usage data for UBC WLAN
Generate a mathematical model of UBC WLAN using traffic and usage data
Formulate conclusions based on the mathematical model and generated graphs
II - BACKGROUND & MOTIVATION
Expand upon previous WLAN studies performed at Stanford, Dartmouth, MIT, and UC Davis.
Gain knowledge of traffic patterns on a large production WLAN to facilitate automated channel assignment
Provide information for network architects to build scalable wireless networks and anticipate growth
IV - ANTICIPATED OUTCOMES
Find patterns in traffic data and network usage depending on time of day, day of week
Discover network load patterns between different building categories
Determine which parts of campus have the busiest AP’s
