1. Electrical and Computer Engineering PeopleFinder Vitaly Gordievsky Alex Trefonas Scott Richard Matt Beckford Preliminary Design Review

2. 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. 3 Electrical and Computer Engineering  More than 110 million active users  Facebook is the 4th most- trafficked website in the world (comScore)  Facebook is the most- trafficked social media site in the world (comScore)  More than 400,000 developers and entrepreneurs  Over 24,000 applications have been built on Facebook Platform  140 new applications added per day  More than 95% of Facebook members have used at least one application built on Facebook Platform General Growth * Background *http://www.facebook.com/press/info.php?statistics

4. 4 Electrical and Computer Engineering Background (continued)  Cell phones are becoming increasingly popular with applications and WIFI iPhone Android (open source)  “90% of the US population have cell phones” - Roberto Padovani  People feel the need to keep close contact with friends  People want to know where their friends are and what they are doing

5. 5 Electrical and Computer Engineering  Purpose of PeopleFinder Locate friends on university campus through wireless connectivity and 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 End users improve the functionality continually Free Concept

6. 6 Electrical and Computer Engineering Vision  User Interaction Location updates to/from Facebook Cell phone (iPhone) Desktop/Laptop Friends’ location displayed on campus map

7. 7 Electrical and Computer Engineering Design Challenges  Location How do I know where I am on campus/building?  Wireless communication How do I connect to the UMASS wireless network and collect information?  Facebook/Windows Application How do I interact with the API?  Third-party server How do I create and maintain robust and versatile databases that will be easy to work with

8. 8 Electrical and Computer Engineering Design Solutions  Wired/Wireless  Facebook Application (UI) Interactive map  Third Party Server Stores relevant location information  Windows Application C++ using Windows API Runs in background Address Resolution Protocol (ARP) Identify MAC address of nearby routers Triangulate location from user-created database of signal strengths

9. 9 Electrical and Computer Engineering Block Diagram HTTP NDIS Protocol Internet Facebook Our Third Party Web Server User’s Laptop Windows PeopleFinder.exeWeb Browser Wireless Card Wired Network Card MySQL database Apache / PHP server PeopleFinder App. Vitaly Gordievsky Alex Trefonas Scott Richard Matt Beckford Team Gong

10. 10 Electrical and Computer Engineering Facebook Application  Social networking growth Users make the program better continually by providing new data to application Users see their friends using PeopleFinder Rapid growth from new users  User Interface Users interact with PeopleFinder solely through Facebook  Privacy Settings User sets which of their friends are allowed to view location All other users are represented by unlabeled dots or hidden

11. 11 Electrical and Computer Engineering Third Party Server  Stores table of known network locations  Communicates with the Facebook application  Stores all relevant user data  Apache server with PHP (for dynamic content) and MySQL (database framework) installed  Server located in datacenter in US Highly reliable Fast processing

12. 12 Electrical and Computer Engineering Windows Application  Specifications PeopleFinder.exe Minimal user configuration Runs in background of Windows Periodically scans for new wireless signals Looks at existing wired connections Communicates with third party server with HTTP requests

13. 13 Electrical and Computer Engineering Design Alternatives  GPS Keychain transmitter/receiver  Poor man’s GPS Hot spots  WIFI triangulation  Manually map out campus ourselves

14. 14 Electrical and Computer Engineering Realistic Constraint  Waterfall processes (Time constraint 8 months) The best-known and oldest process is the waterfall model, where developers are to follow these steps in order:  Requirements specification (AKA Verification) (1 month)  Design (2 months)  Construction (AKA implementation or coding) (2 month)  Integration(1/2 month)  Testing and debugging (AKA validation) (1/2 month)  Installation (AKA deployment) (1 month)  Maintenance (forever)

15. 15 Electrical and Computer Engineering Feasibility  Facebook provides an easy to use API for developing new applications  Low startup costs  All UMass routers have static MAC addresses  NDIS protocols allow communication between the network interface card and your Windows programs Can be programmed easily using Windows Visual Studio  Many Facebook users are enthusiastic about trying new applications

16. 16 Electrical and Computer Engineering Team Roles  Project Manager Vitaly  Application Layer PHP/MySQL Alex C++/ Win app Scott  GUI design Vitaly Matt

17. 17 Electrical and Computer Engineering MDR Deliverables  Data table of signal strengths  Windows User Interface
