Project Overview


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.

Action Items from the last presentation.

Create USE Spec. to make sure that the rout is valid as the following:



class Routattributes

Session:IntegerStarttime: StringStartPoint: PointEndPoint: Point

end

--each rout contains more than one pointassociation UserDevice between

Rout[1] role theRoutPoint[1..*] role thePoints

End

class Pointattributes

Latitude: IntegerLongitude: IntegerTime: IntegerLastUpdate: IntegerDirection:IntegerAccuracy:IntegerLocationMethod:IntegerSessionID: IntegerSpeed: 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)) )



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){ … }



Project Plan – Cost Estimate Approximately 190 total hours (All

Phase) 22 hours research 48 hours documentation 28 hours design 106 hours coding 1000 SLOC



Productivity 1000 SLOC / 106 hours = 9.43 SLOC/hour 10 Documents / 48 hours = 0.2 Docs/hour

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.

Performance testing.


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.

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.


Future Work


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)
