3. Project Overview Department of Computing and Information Sciences - Kansas State University  Goal:  To develop an application for tracking mobile devices which came with GPS functionality with it.  Motivation:  The motivation of developing this project has been my desire of learning more about Mobile programming technology. Moreover, I want to apply what I learned about development lifecycle.

5. Action Items Department of Computing and Information Sciences - Kansas State University  Action Items from the last presentation.  Updating Presentation Tier Chart Data Tier MySQL Server Business Tier JSP ScriptsPHP Classes Presentation Tier HTML files

6. Action Items (Cont.) Department of Computing and Information Sciences - Kansas State University  Action Items from the last presentation.  Create USE Spec. to make sure that the rout is valid as the following:

7. Action Items (Cont.) Department of Computing and Information Sciences - Kansas State University class Rout attributes Session:Integer Starttime: String StartPoint: Point EndPoint: Point end --each rout contains more than one point association UserDevice between Rout[1] role theRout Point[1..*] role thePoints End class Point attributes Latitude: Integer Longitude: Integer Time: Integer LastUpdate: Integer Direction:Integer Accuracy:Integer LocationMethod:Integer SessionID: Integer Speed: integer end context Rout inv correctPath: Rout.allInstances->forAll(r | r.thePoints->exists(p1, p2 | p1.sessionID = p2.sessionID implies (p1.LastUpdate < p2.Last Update or p1.LastUpdate > p2.LastUpdate)and ( r.StartPoint <> p2 and r.EndPoint <> p1)) )

8. Action Items (Cont.) Department of Computing and Information Sciences - Kansas State University  Create JML Specification  getLocation is an important function that extract the information of a certine location and update the DB and the map in the cell pone  //@requires location != null;  //@ensures \fresh(azimuth);  //@assignable oldCoordinates, currentCoordinates, queryString ;  //@signals (Exception e) this.getUrl(queryString) == null;  private void getLocation(Location location){ … }

9. Action Items (Cont.) Department of Computing and Information Sciences - Kansas State University  Project Plan – Cost Estimate  Approximately 190 total hours (All Phase)  22 hours research  48 hours documentation  28 hours design  106 hours coding  1000 SLOC

10. Action Items (Cont.) Department of Computing and Information Sciences - Kansas State University  Productivity  1000 SLOC / 106 hours = 9.43 SLOC/hour  10 Documents / 48 hours = 0.2 Docs/hour

11. Component Design Department of Computing and Information Sciences - Kansas State University

12. Component Design (Cont.) Department of Computing and Information Sciences - Kansas State University  Attributes:  startTime : The time of the session starts.  lastUpdate : The last time the agent send the point information  startPointLatitude : Position of the start point.  startPointLongitude: Position of the start point.  totalTime : Total time form the first point to the last one.  distance : Total distance from the fist point.  sessionID : A unique ID of the session.  phoneNumber : The id of the user and device.   Methods:  calculateSpeed ( ) : Integer  Method to calculate the average speed.  calcTime ( ) : String  resetSession ( [in] id : String ) : Boolean  This method is responsible for delete all previous points and make the last one as the starting point.

14. Performance testing. Department of Computing and Information Sciences - Kansas State University  Apache's ab2 used to compute how many requests per second are systems capable of serving.  The used command is the following:  ab2 -c5 -n1000 http://people.cis.ksu.edu/~bakor/MSEProject/includes/myfiles/getgooglemap2.php C5: concurrency of 5 N1000: The page will be requested 1000 times  Standard deviation [+/-sd] of a random variable, or population or multistep of values is a measure of the spread of its values.  The time of calling getgooglemap2.php page representing the time needed to receive location information from a device.

16. Project Evaluation Department of Computing and Information Sciences - Kansas State University PhaseStart Time Finish Time Phase 1 1-15-2009 1 – 26 – 2009 (11 day) Phase 2 1 – 26 - 2009 2 – 16 – 2009 (20 day) Phase 3 2 – 16 - 2009 5 – 6 – 2009 (40 day)

17. lessons learned  learning more about Mobile programming technology.  Learn to focus in cretin tasks and learn how to measure the effort for each task.  Working with and understanding more, the UML model. Department of Computing and Information Sciences - Kansas State University

18. Future Work Department of Computing and Information Sciences - Kansas State University  Apply the code to calculate location based on the Cell Tower location.  Apply offline GPS recording mode.  Develop.NET agents to extend device coverage (Currently Symbian OS, BlackBerry OS, iPhone OS (OS X iPhone) are covered)
