Project Proposal

Overview

It always seems like an impossible task to find an open table to work or a quick line for food across the WashU campus. BusyBear's goal is to create a database that is accessible to WashU students that will show the population and busyness trends of popular locations on campus, beginning with Bear's Den. By using a network adapter connected to the Raspberry Pi, we will receive an approximate measurement of busyness based on the number of found MAC addresses for a specific region. By looking at pictures taken simultaneously with the MAC address collection, a historic trend between the number of found MAC addresses and relative busyness can be determined. We hope to be able to store this information in a database hosted by AWS and display this data on a website. Our end goal is to gather information to allow the WashU community to create more educated decisions regarding where to go and when to go there.

Objectives

  • Learn and be able to code in Python as related to the Pi
  • Use sniffing/MAC tracking method in the analysis of busyness
  • Investigate the use of the camera in the analysis of busyness
  • Be able to monitor busyness fairly accurately by filtering detected devices
  • Compare busyness at different times of day and between buildings
  • Design a GUI for an aesthetically pleasing and useful website
  • Host a website displaying useful and relevant data through Amazon Web Services (AWS)

Challenges

  • Limited experience with working with WiFi receivers or anything to do with MAC Addresses
  • Limited knowledge of Python and Raspberry Pi

Design and Solutions

Build the Device

We began by constructing a device to collect MAC addresses. Initially, we hoped that with the RaspberryPi's WiFi capabilities, we could simply use the base hardware for detection. We quickly determined that the RaspberryPi was not capable of entering a monitoring mode[1]; we would need external hardware to serve this purpose. We went through a variety of external network adapters, and ultimately found one with both monitoring mode capabilities and compatibility with the RaspberryPi [2]. Using the Network Adapter's functionality will be explored further in the Collect Information section and in the Network Adapter in Monitoring Mode tutorial[3].
We decided that a RaspberryPi camera should be added to the device to strengthen the validity of the data gathered from the network adapter. The Pi Camera is fairly simple to connect and the functionality is implemented through Pi commands[4]. By analyzing a combination of the number of addresses collected and the visual busyness found in the picture, more accurate trends over time can be determined.

Collect Information

In the before mentioned tutorial [Network Adapter Monitoring Mode Tutorial] we established how setup the network adapter in monitoring mode and install kismet, the software we used to utilize monitoring mode. Once properly configured, simply calling kismet spews out text into the console as so:

We could collect data, but we needed a way to be able to consolidate the MAC Addresses, find out what device it belonged to, and upload that information to the database all periodically throughout a gap of time. Over a couple of months, we finalized our data collection design to utilize crontab [5] , a program used the schedule execution of programs at certain times.

Put It All Together

While the RaspberryPi gives us data and the website gives us a way to communicate data, we next need to combine these pieces in an understandable and usable manner. We need to fully understand the relationship between the number of MAC addresses found and the actual level of busyness as it relates to real-world environments. Because we have yet to collect data over time and relate this number to the people in a specific area, we cannot expand on our complete thought process yet. At the moment, we imagine there will be a linear relationship between the number of MAC addresses and the relative busyness. As the number of MAC addresses increase, the level of busyness will directly increase. At the moment we are attempting to determine at exactly what rate this change occurs. This relationship will be determined by looking at the number of MAC addresses and comparing that number to the number of people visible in our captured image. By looking at this relationship over time, a general understanding can be determined for our specific location on campus, Bear's Den.
