1. INTRODUCTION

1.1 Existing System

To perform any manipulations, a person must be in front of the system.

Suppose if person willing to shutdown a system his presence is necessary and if

he wish to perform the same task from anywhere else. It takes more time. In this

sense it is a time consuming process.

With the Bluetooth we can access only to some limited range. If a particular

person intended to send a file which is far away then this is not applicable, this

means that beyond the Bluetooth limit we cant perform any operations.

1.2 Proposed System

It would be easier, if there is software with which we can access from

anywhere through mobile which is connected to our system.

Now-a-days most of the people carry mobiles. So, using this application all

tasks may be completed form the place where we are i.e., mobility and flexibility

is provided.

As we perform any file operations, handling the system and mail related

Operations using mobile. From any place in spite of being in front of the system,

it saves the time.

2. FEASIBILITY STUDY

Feasibility study is the high level capsule version of the entire requirement analysis

process. The objective of feasibility study is to determine whether the proposed system

can be developed with available resources. There are three steps to be followed for

determining the feasibility study of proposed system.

Technical Feasibility

Operational Feasibility

Economical Feasibility

TechnicalFeasibility:

It is concerned with hardware and software feasibility. In thisstudy, one has to test whether the proposed system can be developed using existing

technology or not. If new technology is required, what is the likely hood that it can be

developed.

OperationalFeasibility:

Operational feasibility determines whether the proposed system

satisfied the user objectives and can be fitted in to current system operation. The

proposed system Mobi-System can be justified.

EconomicalFeasibility:

This includes an evaluation of all incremental costs and

benefits expected if proposed system is implemented. Costs-benefit analysis which is to

be performed during economical feasibility delineates costs for project development and

weighs them against benefits of system.

4. SYSTEM REQUIREMENT SPECIFICATION

In the present world, every time it is not possible to carry computer or laptop along with

person and it is a major disadvantage that, person cannot access his/her own system from remotearea. Like he/she cannot upload his/her own system files through internet and cannot create or

modify or delete files on his/her system.

To overcome this problem, there should be a certain feature, so that person can operate

his/her system through mobile where he/she can create or modify or upload or delete his/her own

system files from remote area, without carrying the system. Person can get email alerts to his/her

mobiles and person can access and get up-to-date data.

According to our analysis, we have found the following modules.

1.Audioplayer

2.FileManagement

3. ControlPanel

4.E-mail

5. Registration

1. TECHNOLOGIES USED

WhatisPHP?

y PHP stands forPHP:Hypertext Preprocessor

y PHP is a server-side scripting language, like ASPy PHP scripts are executed on the server

y PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL,Generic ODBC, etc.)

y PHP is an open source softwarey PHP is free to download and use

WhatisaPHPFile?

y

PHP files can contain text, HTML tags and scriptsy PHP files are returned to the browser as plain HTMLy PHP files have a file extension of ".php", ".php3", or ".phtml"

Why PHP?

y PHP runs on different platforms (Windows, Linux, UNIX, etc.)y PHP is compatible with almost all servers used today (Apache, IIS, etc.)

y PHP is easy to learn and runs efficiently on the server side

Whereto Start?

To get access to a web server with PHP support, you can:

y Install Apache (or IIS) on your own server, install PHP, and MySQL

y Or find a web hosting plan with PHP and MySQL support

BasicPHP Syntax

A PHP scripting block always starts with . A PHP scripting block can be

placed anywhere in the document


9/83

9

A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code.

Each code line in PHP must end with a semicolon. The semicolon is a separator and isused to distinguish one set of instructions from another.

There are two basic statements to output text with PHP:echo and print. In the exampleabove we have used the echo statement to output the text "Hello World".

My SQL

WhatisMySQL andwhy areweusingit?

MySQL is a powerful Relational Database Management System (RDBMS) which we will use to

learn the basic principles of database and data manipulation using Structured Query Language

(SQL) statements. SQL is a database language that is used to retrieve, insert, delete and update

stored data. This is achieved by constructing conditional statements that conform to a specific

syntax (i.e. the strict order required of elements for a statement to work).

Although it is assumed that most people reading this know what a database and SQL are (if not

necessarily how to use them), there follows a little recap that it does no harm ;-)

HowdoesMySQL work?

MySQL is a database server program and as such is installed on one machine, but can 'serve' the

database to a variety of locations. To explain look at the following diagram.


10/83

10

The MySQL Server is installed on a Server and can be accessed directly via various client

interfaces, which send SQL statements to the server and then display the results to a user. Some

of these are:

A Local Client - a program on the same machine as the server. An example of this is the

command line MySQL client software we will be using in the rest of the MySQL workshops

(although there are other programs including graphical interfaces).

A Scripting Language - can pass SQL queries to the server and display the result.

A Remote Client - a programme on a different machine that can connect to the server and run

SQL statements.

You can also use two more indirect methods.

Remote Login - You may be able to connect to the Server Machine to run one of its local

clients.


11/83

11

Web Browser - you can use a web browser and scripts that someone has written (we're going to

use this method for the rest of the workshop).

J2ME

J2ME (Java2MicroEdition) is an advanced technology in Java, developed with the help of

Java Community ProcessProgram. J2ME is a reduced version of the Java API and JavaVirtual Machine that is designed to operate within the limited resources available in the

embedded computers and microcomputers.

J2ME is targeted to developers ofintelligentwirelessdevicesandsmallcomputingdevices

who need to incorporate cross-platform functionality in their products. A key benefit of usingJ2MEiscompatibility withall Java-enableddevices. Motorola, Nokia, Panasonic all have

Java-enabled devices. A J2ME application is a balance between local and server-side processing.

Programs

A MIDlet is a classthatextendstheMIDletclass and is the interfacebetweenapplication

statementsandtherun-timeenvironment , which is controlled by the applicationmanager .

A MIDlet class must contain threeabstractmethods that are called by the application managerto manage the life cycle of the MIDlet. These abstract methods are.

y startApp(): called by the application manager when the MIDlet is started and contains

statements that are executed each time the application begins execution. Public and haveno return value nor parameter list.

y pauseApp(): called before the application manager temporarily stops the MIDlet. Theapplication managerrestartstheMIDletby recallingthestartApp() method. Public

and have no return value nor parameter list.y destroyApp(): called prior to the termination of the MIDlet by the application manager.

Public method without a return value. It has a boolean parameter that is set to true if thetermination of the MIDlet is unconditional, and false if the MIDlet can throw a

MIDletStateChangeException.

The Basic Midlet Shell.

public class BasicMIDletShell extends MIDlet

{

public void startApp(){ }public void pauseApp(){ }public void destroyApp( boolean unconditional){ }

}

MIDPAPI classes are used by the MIDlet to interact with the user and handle data management.

Userinteractions are managed by userinterfaceMIDPAPI classes. These APIs prompt the

user to respond with an appropriatecommand. The command causes the MIDlet to executeone ofthreeroutines:

y Perform a computation.y

Make a network request.y Display another screen.y

Bluetooth Device:

BluetoothApplications:

Bluetooth is designed to operate in an environment of many users. Up to eight devices can

communicate in a small network called a piconet. Ten of these piconets can coexist in the samecoverage range of the Bluetooth radio. To provide security, each link is encoded and protected

against eavesdropping and interference.

Bluetooth provides support for three general application areas using short-range wireless

connectivity:

y Dataandvoiceaccesspoints - Bluetooth facilitates real-time voice and datatransmissions by providing effortless wireless connection of portable and stationary

communications devices;y Cablereplacement - Bluetooth eliminates the need for numerous, often proprietary cable

attachments for connection of practically any kind of communications device.Connections are instant and are maintained even when devices are not within line of

sight. The range of each radio is approximately 10 m, but can be extended to 100 m withan optional amplifier;

y Adhocnetworking - A device equipped with a Bluetooth radio can establish instantconnection to another Bluetooth radio as soon as it comes into range.

Bluetooth Standards Documents

The Bluetooth standards present a formidable, divided into two groups: core and profile. The

core specifications describe the details of the various layers of the Bluetooth protocolarchitecture, from the radio interface to link control. Related topics are also covered, such as

interoperability with related technologies, testing requirements, and a definition of variousBluetooth timers and their associated values.

The profile specifications are concerned with the use of Bluetooth technology to support various

applications. Each profile specification discusses the use of the technology defined in the corespecifications to implement a particular usage model. The purpose of a profile specification is to

define a standard of interoperability, so that products from different vendors that claim to supporta given usage model will work together

The Bluetooth developer must wade through the many documents with a particular application in

mind. The reading list begins with coverage of some essential core specifications plus the

general access profile. Following a basic set of documents, the reading list splits along two lines,depending on whether the reader's interest is in cable replacement or wireless audio.

ProtocolArchitecture

Bluetooth is defined as a layered protocol architecture consisting of core protocols, cablereplacement and telephony control protocols, and adopted protocols.

The core protocols form a five-layer stack consisting of the following elements:

y Radio - Specifies details of the air interface, including frequency, the use of frequency

hopping, modulation scheme, and transmit power.y Baseband - Concerned with connection establishment within a piconet, addressing,

packet format, timing, and power control.

y Linkmanagerprotocol (LMP) - Responsible for link setup between Bluetooth devicesand ongoing link management. This includes security aspects such as authentication and

encryption, plus the control and negotiation of baseband packet sizes.y Logicallinkcontrolandadaptationprotocol (L2CAP) - Adapts upper-layer protocols

to the baseband layer. L2CAP provides both connectionless and connection-orientedservices.

y Servicediscovery protocol (SDP) - Device information, services, and the characteristicsof the services can be queried to enable the establishment of a connection between two or

more Bluetooth devices.

Bluetooth specifies a telephony control protocol. TCS BIN (telephony control specificationbinary) is a bit-oriented protocol that defines the call control signaling for the establishment of

speech and data calls between Bluetooth devices. In addition, it defines mobility-managementprocedures for handling groups of Bluetooth TCS devices.

2. CLIENT-SERVERARCHITECTURE

A network architecture in which each computer or process on the network is either aclientor server.

Components:

Clients

Servers

Communication Networks

Clients:

Applications that run on computers

Rely on servers for

Files

Devices

Processing power

Example:E-mail client

An application that enables you to send and receive e-mail

Server:

Computers or processes that manage network resources

Disk drives (file servers)

Printers (print servers)

Network traffic (network servers)

Example: Database Server

A computer system that processes database queries

Communication Network:

y Networks Connect Clients and Servers

ClientServer Computing:

Process takes place

on the server and

on the client

Servers

Store and protect data

Process requests from clients

Clients

Make requests

Format data on the desktop

Client-server architecture can be considered as a network environment that exchanges

information between a server machine and a client machine where server has some resources that

can be shared by different clients.

Client-ServerArchitecture

Client-server architecture can be considered as a network environment that exchanges

information between a server machine and a client machine where server has some resources that

can be shared by different clients.

In a Client/server architecture individual computers (known as clients) are connected to a

central computer which is known as Server.

Lets take an example of a file server to understand the core process of a client/server

network, the file server acts as a storage space on the network for the files, spreadsheets,

databases, etc.


17/83

17

Instead of storing these records on every individual computer, the file server allows the

clients to store their files on one central computer and make them sharable. The client-server

architecture is beneficial in reducing the multiple iterations of a single file and allowing the

organization to have one centralized point for every computer to access the same file.

The interaction between a lamp and an electrical socket can be considered as a interaction

between client and server is just like. In the example the electrical socket is just like a server and

the lamp works like a client.

7. Testing

Testing is the process of detecting errors. Testing performs a very critical role for quality

assurance and for ensuring the reliability of software. The results of testing are used later on

during maintenance also.

Psychology ofTesting

The aim of testing is often to demonstrate that a program works

by showing that it has no errors. The basic purpose of testing phase is to detect the errors that

may be present in the program. Hence one should not start testing with the intent of showing

that a program works, but the intent should be to show that a program doesnt work. Testing

is the process of executing a program with the intent of finding errors.

Thetestingprocess:

Component (orunit)testing:

y Testing of individual program components

y Usually the responsibility of the component

y Developer (except sometimes for critical systems)

y Tests are derived from the developers experience.

Systemtesting:

y Testing of groups of components integrated to create a system)

y The responsibility of an independent testing team

y Tests are based on a system specification.

Testingprocessgoals:

Validationtesting:

y To demonstrate to the developer and the system customer that the software meetsits requirements;

y A successful test shows that the system operates as intended.


81/83

81

Defecttesting:

y To discover faults or defects in the software where its behavior isincorrect or not in behavior is incorrect or not in conformance

with its specification;

y

A successful test is a test that makes the system performincorrectly and so exposes a defect in the system.

y Test show the presence not the absence of defects

Blackboxtesting:

It is also called functional testing and behavioral testing, focuses on determining whether or not a

program does what it is supposed to do based on its functional requirements. _ No knowledge ofinternal structure of code.

White-box:

White-box testing is testing that takes into account the internal mechanism of a system or

component. White-box testing is also known as structural testing, clear box testing, and glassbox testing.

Integration Testing:

Integration testing is testing increments of the system; release testing involves testing a system to

be released to a customer.

Involves building a system from its components and testing it for problems that arise from

component interactions.

Top-downintegration:

Develop the skeleton of the system and populate it with components.

Bottom-upintegration:

Integrate infrastructure components then add functional components.

To simplify error localization, systems should be incrementally integrated.
