ABSTRACT

Short Message service (SMS ) became a basic building block for now a days communication , it is not only to share text data but also for location prediction using Global positioning system (GPS).

Location prediction is performed by using the current location, moving speed, and bearing of the target to predict its next location.

When the distance between the predicted location and the actual location exceeds a certain threshold, the target transmits a short message to the tracker To update its current location.

ABSTRACT (CONTD….)

The threshold is dynamically adjusted to maintain the location tracking accuracy and the number of short messages on the basis of the moving speed of the target.

The experimental results show that (Location Based Delivery) LBD, indeed, outperforms other methods because it satisfactorily maintains the location tracking accuracy with relatively fewer messages

LITERATURE SURVEY Short Message service is a mobile communication

service for exchanging text messages between mobile devices

In most of the hand held devices Global positioning system (GPS) became pervasive. Therefore, several location-tracking applications have been developed.

The GPS is used to obtain the location information of a target . Portable Device (PD) works used either an 802.11 wireless network or the short message service (SMS) to transmit the location information of a target to a tracker .

In this project a novel method called location-based delivery (LBD), which combines SMS and GPS, is proposed, and further, a realistic system to perform precise location tracking is developed

EXISTING SYSTEM

Distance Based approach : This approach processes the message by applying the “store and forward” mechanism. If the recipient is unreachable, the SMS Center queues the message for a retry at a later time

The messages are transmitted between an SMSC and a handset by the mobile application part. This signaling protocol limits the message payload length to 140 bytes

The number of SMS transmissions must be minimized while maintaining the location tracking accuracy within the acceptable range to reduce the transmission cost.

A handful of studies have developed location tracking applications through SMS. However, SMS is a user-pay service.

EXISTING SYSTEM

Disadvantages:

message payload length is only140 bytes

The number of SMS transmissions are more since there is no

mechanism for threshold .

SMS is a user-pay service so more SMS incur more cost.

No accurate data for location Prediction.

PROPOSED SYSTEM

The three main features of the proposed Location Based Delivery (LBD) approach are

well-defined SMS format location prediction module dynamic threshold module

The location prediction module: which is built in both the target and the tracker side, uses the information on the current location, moving speed, and bearing of the target to predict its next location.

The dynamic threshold module: which is used only on the target side, minimizes the number of short messages by dynamically adjusting the threshold TH according to the moving speed of the target.

STRUCTURE OF THE LBD SYSTEM

Location prediction : It is performed by using the current location, moving

speed and bearing of the target predicted.

The dynamic threshold : which is used only on the target side, minimizes the

number of short messages by dynamically adjusting the threshold TH according

to the moving speed of the target.

The tracker : It periodically updates the location of the target on the local

screen according to the predicted location.

The target : transmits the actual location update information to the tracker.

STRUCTURE OF THE LBD SYSTEM

SYSTEM ARCHITECTURE

The tracker side comprises the following components:

SMS Switch

SMS Receiver

Predictor, and

Offline Map

The target side comprises the following components:

SMS Locator

SYSTEM MODULES

The three modules of the proposed Location Based Delivery (LBD) approach are

Well-defined SMS formatLocation prediction module Dynamic threshold module

WELL-DEFINED SMS FORMAT

Well-defined SMS format: It increases the messages length.

THE LOCATION PREDICTION MODULE

The location prediction module:

It is built in both the target and the tracker side, uses the information on the current location, moving speed, and bearing of the target to predict its next location.

When the distance exceeds the threshold, i.e. D > TH, the target transmits a short message to the tracker to indicate its actual location, moving speed, and bearing.

If the distance is less than the threshold, the target does not send a short message to the tracker.

THE DYNAMIC THRESHOLD MODULE

The dynamic threshold module :

It is used only on the target side, minimizes the number of short messages by dynamically adjusting the threshold TH according to the moving speed of the target.

It affects both the number of transmitted short messages and the location accuracy.

A large threshold reduces the number of short messages as well

as the location accuracy; that is, there is a large difference between the predicted location and the actual location.

SYSTEM IMPLEMENTATION

o In this project, for implementation purpose Java is chosen as the programming language

o In this project, for implementation purpose Windows XP platform is used & reasons for choosing this platform are Integrated Networking support, More stable and secure than previous version, Contain remote desktop connection and restore option.

o The project has been implemented using android platform on Windows XP.

SCREEN SHOTS

CONCLUSION

o LBD is used for estimating the location of target.

o In addition to defining the short message format, LBD uses the current location, speed, and bearing of the target to predict its next location.

o In LBD, the moving pattern information of the target is transmitted only when the distance between the predicted location and the actual location exceeds a certain threshold.

o Dynamic Threshold method is used to inform the target to transmit the location information to the tracker.
