Electrical and Computer Engineering PeopleFinder Vitaly Gordievsky Alex Trefonas Scott Richard Matt Beckford Midway Design Review

2 Electrical and Computer Engineering Background  Wide spread use of social networking sites Facebook MySpace Many clones of Facebook  Facebook is particularly popular amongst college students Major Graduation Year List of courses Status Bar

3 Electrical and Computer Engineering  Purpose of PeopleFinder Locate friends on university campus through wired and wireless connectivity on Facebook application The application to use before making a call Easily available and convenient Brings friends together one step closer Quickly know status and location of friends  Features Available to all Facebook users in UMASS network Interactive map displaying user locations Free to use Concept

4 Electrical and Computer Engineering Design  Web-server hosted by (HostGator)  MySQL Database  Windows executable (fetches user ID and MAC)  Interactive Flash Map  Facebook Application for Integration

5 Electrical and Computer Engineering Block Diagram Internet Facebook Our Third Party Web Server User 1 Laptop Windows PeopleFinder.exe Web Browser Wireless Card Wired Network Card MySQL database Apache / PHP server PeopleFinder App. Facebook Our Third Party Web Server User 2 Laptop Windows PeopleFinder.exe Web Browser Wireless Card Wired Network Card MySQL database Apache / PHP server PeopleFinder App.

6 Electrical and Computer Engineering MDR Specifications  Setup XAMPP for development testing  Register Facebook application  Create relevant MySQL database tables  Create program with Visual Studio to get MAC Address of the router and user ID  Create an interactive interface for Facebook Application (Flash)

7 Electrical and Computer Engineering Gantt Chart

8 Electrical and Computer Engineering Project Specifications  Server load time: Under 50ms  Brower page rendering time: Under 4s  Location Accuracy: Depends on the distance from the router (usually under 400ft)  Map update time: 20s

9 Electrical and Computer Engineering Data  Browser page rendering time Goal: under 4 seconds on most computers  Average Time = sec  Standard deviation = sec

10 Electrical and Computer Engineering PHP Server load time  Time it takes for our third party server to generate the webpage  Depends on number of friends of Facebook user  604 friends – ms with standard deviation of.289  124 friends – ms with standard deviation of.275ms

11 Electrical and Computer Engineering Flash Interface  Needs to be integrated with Facebook application through HTML  Coordinates need to be stored in MySQL database  Demo only shows the basic concept of the user interface.

12 Electrical and Computer Engineering Design Challenges  Forced to use API’s for Flash and PHP due to Facebook security restrictions for applications  1 MAC address for large area on the UMASS wireless network - from campus center to engineering lab.  Portability of Windows application

13 Electrical and Computer Engineering MAC Address Retrieval Wired Connections:  Using (ARP) protocol and windows API’s Mapping a host's link layer (MAC address) when only its Internet Layer (IP) is known. Internet Layer Wireless Connections:  Obtain information about access points within wireless range  Record signal strength received from various nodes  Correlate signal strength over time (statistical averages)

14 Electrical and Computer Engineering Windows Application Specifications PeopleFinder.exe (sdpapp.exe for MDR) Minimal user configuration Runs in background of Windows 1 ) Asks user for input : Facebook User Id Number 2 ) Sends http request to refresh ARP table entries 3 ) Runs arp.exe and obtains routers MAC address 4 ) Packages userid and macaddress for server 5 ) Sends http request to server

15 Electrical and Computer Engineering Virtual Windows Application Demo

16 Electrical and Computer Engineering Facebook Application  Main interface for PeopleFinder  Clean and easy to use  Eventually all Facebook users can add application  Communicates with 3 rd Party Server using PHP API  Contains Flash Map  Canvas PHP page includes Flash map and shows debugging data for application  (currently only developers can access)

17 Electrical and Computer Engineering MySQL Database  2 Tables to contain user data and location data  MAC addresses of router  Locations of routers  Unique Facebook ID’s of users  Signal strengths of various access points in Range  Last login times  Last locations of users

18 Electrical and Computer Engineering 3 rd Party Server  Hosted with XAMPP on local server on Umass network  Includes PHP and MySQL server  Stores all user and location data  Pages requested by facebook.com  Communicates with Windows executable to update user locations  Passes HTML and FBML (facebook markup language) to facebook.com

19 Electrical and Computer Engineering Realistic Constraint  Long page load times for all Flash applications and Facebook site (over 3 seconds)  Cannot open ports on UMass network due to Firewalls, so web server needs to be hosted off-campus

20 Electrical and Computer Engineering Budget  Due to the nature of our project and design we did not need to borrow any money from the Department of Electrical Engineering Item(s)Total CostBalance Initial Funding---$ Hardware Purchases NA--- PCBNA--- Software Purchases $0.00$ Web Hosting$45.00$ Midway Balance---$455.00

22 Electrical and Computer Engineering MDR Deliverables Setup XAMPP Register Facebook application Create database tables Create program with Visual Studio to get MAC Address of the router and user ID  Create an interactive interface for Facebook Application (Flash) Needs to be integrated with Facebook

23 Electrical and Computer Engineering Achievement  Demo of Facebook Application  Demo of Flash Map  Demo of MySQL database
