to communicate and have access to another computer when physical access to the

computer is not possible or convenient.

Figure 1: Initiating connection

The following tasks can be performed using this application:

Chat – The user and its partner is able to chat with each other. This help user to get

any information or solution of their problem and also to share his knowledge with

others.

File Transfer - The file transfer service is a method of transferring files. There is no

apparent limit on the size of files transferred with this method. This service is

available during one-on- one sessions only. Through the file transfer service, users can

transfer files from almost anywhere on their system or from the remote system.

Remote Control - Remote control is the ability to control a system from a secondary

location other than that of the primary location of the system being accessed. Using

this, the user can view the system in which their partner is working on.

Software Requirement Specification

3.1 Introduction

The purpose of this SRS is to cover all the different areas for the project requirements.

The documents will also include all the input / outputs / assumption / actions /

dependencies for the project.

3.1.1 Overview

Remote sharing application allows an individual to communicate and have access to acomputer when physical access to the computer is not possible or convenient. With

remote viewing software, a user can access his or her computer through LAN. No

internet connection is needed. The only thing which requires is server IP address and

you will be able to connect to others members through LAN.

As it is based on LAN. LAN is a network which connect client to main server. So we

have used the same concept here we are connecting client and server with each other

and by providing the IP address we can communicate with each other.

Figure 2: Connection using LAN

Basically, there are three components which plays an important role so that Remote

Sharing application could work. They are:

Remote Server

The part which awaits the client to connect in the port opened for connection is

termed as Remote Server.



9

This part usually interact with Client and exchange files with each other and

receives the screenshot of the client and loads the image thus received in a

frame. The frame then starts listening mouse and key events. The key and

mouse events thus received are sent to the client computer through network.

Remote ClientThis part usually connect with server and interacts with it, exchange files but

the core function of this part is to send the screenshots of the computer to the

server part in certain interval and to implement the mouse and key events sent

from the server part.

Network

Network can be defined as the way of communication in this context. It is the

medium through which the server and client can interact with each other.

However, the network used to setup for remote sharing app is through LAN.

In this particular project we are going to establish the connection between the

server and client through LAN. The connection between the server and client

must be authorized. For this purpose we have implemented simple way in

which the client only, is able to connect to the server, feeding the IP address of

the server in the client module. However, the server should be ready to receive

the connection from the client beforehand.

3.1.2 Feasibility Study

The main objective of this study is to determine (Remote Desktop) RD is feasible or

not. Mainly there are three types of feasibility study to which the developed system is

subjected as described below. The key considerations are involved in the feasibility:

1. Technical feasibility

2. Economic feasibility

3. Operational feasibility

The developed system must be evaluated from a technical viewpoint first, and theirimpact on the organization must be accessed. If compatible, behavioural system can

be devised. Then they must be tested for the feasibility. The above three keys are

explained below:

Technical Feasibility

Remote Desktop Application satisfies technical feasibility because this Service

can be implemented as a stand-alone application. It is Microsoft Windows OS

compatible.



10

Economic feasibility

Our project entitled Remote Desktop (RD) is economically feasible because it

is developed using very less amount of economic resources. It is Free.

Operational feasibility

Operational feasibility should be accounted after the software is developed so

that it can cope up with the defined objectives.

The application is user friendly with its GUI and handy to use.

The application is be affordable because the requirement is just normal

computers with working LAN port.

Since this application is developed in Java it runs both on Windows and

Linux system.

3.1.2 Acronyms

S. No. Acronym Explanation

1. LAN

Local Area Network is a computer network that interconnects

computers within a limited area such as a home, school, computer

laboratory, or office building, using network media.

2. FTA

File Transfer Protocol is a standard network protocol used

to transfer computer files from one host to another host.

3. IP

Internet Protocol is a numerical label assigned to each device (e.g.,

computer, printer) participating in a computer network that uses

the Internet Protocol for communication.

4.

GUI

A graphical user interface (GUI) is a human-computer interface (i.e.,

a way for humans to interact with computers) that

uses windows, icons and menus and which can be manipulated by amouse (and often to a limited extent by a keyboard as well).

5.OS

Operating System is the low-level software that supports a computer's

basic functions, such as scheduling tasks and controlling peripherals.

3.2 Existing Business Processes

3.2.1 Introduction

To perform the workflow analysis, it is paramount to understand the existing business

processes completely. This section describes all current business processes and their

interaction with external entities and systems using graphical data flow models.

3.2.2 Use Case Diagram

3.2.2.2 Use Case Description

A use case diagram at its simplest is a representation of a user's interaction with the

system and depicting the specifications of a use case. A use case diagram can portray

the different types of users of a system and the various ways that they interact with the

system.

This type of diagram is typically used in conjunction with the textual use case and will

often be accompanied by other types of diagrams as well.

A use case is an external view of the system that represents some action the user

might perform in order to complete a task. A use case is a set of scenarios that

describing an interaction between a user and a system. A use case diagram displays

12

the relationship among actors and use cases. The two main components of a use

case diagram are use cases and actors.

Actors: An actor portrays any entity (or entities) that perform certain roles in a

given system. The different roles the actor represents are the actual business roles of

users in a given system. An actor in a use case diagram interacts with a use case.

Use case: A use case in a use case diagram is a visual representation of a distinct

business functionality in a system. The key term here is "distinct business

functionality." To choose a business process as a likely candidate for modelling as a

use case, you need to ensure that the business process is discrete in nature.

System Architecture

A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal descriptionand representation of a system, organized in a way that supports reasoning about

the structures and behaviors of the system.

14

A system architecture can comprise system components, the externally visible

properties of those components, the relationships (e.g. the behavior) between them.

It can provide a plan from which products can be procured, and systems developed,that will work together to implement the overall system.

Figure 4: System Architecture of Remote Sharing Application

The above is the architecture diagram of our project. The server module contains

four prime classes namely: GUI Frame, FServer, ChatServer and DesktopServer. The

client module also contains three prime classes namely: GUI Frame, FClient,

ChatClient and DesktopClient.

http://en.wikipedia.org/wiki/System

http://en.wikipedia.org/wiki/System



15

Following are the classes used in this application:

RLogin.class: It creates the basic GUI on both server & client side and

provides an option to tune the computer either as server or client. It also the

necessary inputs for the connection.

DesktopServer.class: It starts the server, binds the port and waits for theconnection. It loads the screenshot received from the client module. It also

captures the keyboard and mouse events and sends over the network to the

client module.

FServer.class: It starts the server, binds the port and waits for the connection.

It generates the basic frame which sends any documents or file to client and

receive any documents or file from the client.

ChatServer.class: It starts the server, binds the port and waits for the

connection. It generates the basic frame which displays the message from the

client and sends the text message to the client.

DesktopClient.class: It starts the client and connects the client to the

specified computer with the provided IP address. It captures and sends the

screenshot and implements the mouse & keyboard events received from the

server.

FClient.class It starts the client and connects the client to the specified

computer with the provided IP address. It generates the basic frame which

sends any documents or file to server and receive any documents or file from

the server.

ChatClient.class: It starts the client and connects the client to the specified

computer with provided IP address. It generates the basic frame which

displays the message from the server and sends the text message to the server.

Other classes used to implement this project are as follows:

Mouse.class: It contains the attributes of mouse event. This class is registered on both

server and client side in order to send the instance of this class over the network.

Key.class: It contains the attributes of keyboard event. This class is registered on both

server and client side in order to send the instance of this class over the network.

ScreenSender.class: It contains attributes of screenshot captured from the client in the

form of byte array. This class is registered on both server and client side in order to

send the instance of this class over the network. he network.

3.4 Potential Areas Of Improvements

3.4.1 Limitations

Though we managed to resolve most of the problems we faced, still there are some

challenges we could not get through. Those challenges led to create some of the

limitations of the application. Some of the limitations of the applications are listed

below:

The keyboard event is limited to single key operation. Combo keys such as Alt

+ Tab, Win + R, Ctrl + Alt + Del etc. are not implemented.

The cursor type of the server side does not change with the change in cursor

type of client side (e.g. On client side the cursor changes to hand form while

pointing to hyperlinks while in server side the cursor remains as it is i.e.

pointed form).

The screenshot image sent from the client takes time to load in server side.

This application doesn’t work in the Internet. It is limited to LAN.

This application can only make TCP connections.

There are no security measures implemented against possible hacking and loss

of data.

There is no facility for multiple clients to connect on single server

simultaneously. Client cannot block specific portion of desktop or program for remote access.

3.4.2 Future Enhancements

We have plans to modify this application for more practical and commercial use.

Hence, we have listed some of the points as future enhancements as below:

Modifying System services.

Voice and Video Chat. Secured Connection

Password Security.

Using the application via the Internet.
