1. Title of the project

BOSCO CHAT (A Wi-Fi Chat Room in Android)

2.Objective

The main objective of this project is to connect different people that are in the range of

same Wi-Fi access point. This will be completely free and no external source of internet

will be needed. The chat will be public, means messages will be broadcasted to every

user that is connected. This application will be developed in the Java programming

language using the android software development kit(SDK).The development platform or

integrated development environment(IDE) is eclipse using the android development

tools(ADT) Plug-in. We will develop an application where user does not need any web

browser to chat with other user. It has its own user interface. The user can connect to any

available Access Point for chat with another user connected with same access point.

Tethering and portable hotspot utility available on android can also be used for creating

an access point. User Datagram Protocol (UDP) is used for sending the packets across the

network.

3.Introduction

„BOSCO‟ is a name extracted from the full name Don Bosco, The Founder of selesian

congregation and „CHAT‟ which means chatting .

With the availability of mobile computing devices, mobile users have a natural tendency to share

information between them. Often mobile users want to have a meeting, even though it is not

planned in advance and there is no Internet connection available. For instance, there may be

situations that employees find themselves together in a meeting room, or friends or business

acquaintances may encounter each other in an airport terminal, or some scholars and researchers

may meet in a hotel ballroom for a conference or workshop. In those situations, requiring each

user to connect to a wide area network to communicate with each other may not be convenient or

practical because of the lack of Internet connectivity or because of the time or cost required for

such a connection, So in those situations the “WiFi Chat Room” would help the employees to

send and receive the information whit the employees want to share. This application will be

based on “Android Operating system”. The chat messages sent are of two types:

1. Public Chat Messages

2. Private chat Messages

4

Public messages are delivered to all other chat clients nearby, while private messages are

directed to a specific recipient. As in most chat applications, there is no history and clients do not

expect to receive messages sent earlier or when disconnected. Disconnection can occur at any

time while clients are exchanging messages.

4.Proposed methodology

ANALYSIS PHASE

1)Analysis different application already

available in market.

2)Study to make new application for user

DESIGN PHASE

1)Make Data flow Diagram.

2)Make Use Case Diagram.

4)Make Activity diagram.

CODING PHASE

TESTING PHASE

1) Program Testing

2)Module Testing

3)Testing the responsiveness of the system.

5.Technical details (h/w & s/w details/Feasibility study)

Hardware:

Desktop or laptop

Additional: android handset

Software:

Operating System: Windows XP (32-bit), Windows Vista (32- or 64-bit), Windows 7 (32- or 64-bit) or Windows 8 (32-bit or 64-bit)

Eclipse IDE:

Eclipse 3.6.2 (Helios) or greater

Eclipse JDT plug-in (included in most Eclipse IDE packages)

JDK 7

Android Development Tools plugin (recommended)

6.Feasibility study:

The feasibility study is done on three phases:

1. Operational

The proposed system is operationally feasible as the final output of the project can be

used by Android user and it will be easy and user friendly for use.

2. Technical

If we see from technical perspective the project is feasible, as the software required for

developing the project is a freeware, easy to use and it doesn‟t demand any non-existing

technology.

3. Economic

Economically, this project doesn‟t raise any issues, as the project itself is planned or

aimed at user needs. The resources required for this project are bare minimum. It doesn‟t

demand any additional resources. The user will be able to download the application from

proper link and after that they can easily use it.

8.Conclusion

BOSCO CHAT (A Wi-Fi Chat Room in Android) is a new approach for local communications

in mobile world. Wi-Fi proximity is a main idea behind Wi-Fi chat. If you and your potential pal

can see at this moment the same Wi-Fi access point (Wi-Fi network) than it is very probably that

you can see each other. In other words, it is very likely that you are close to each other. Close in

the geographical sense, of course. So, BOSCO CHAT lets you create discussions (forums) as

well as live web chats associated with Wi-Fi access points. It is yet another way to create hyper-

local group messaging.
