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.

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. 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.
