Experiment: - 1WIRELESS NOTICEBOARD

1. Problem Definition Notice Board is primary thing in any institution / organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is a difficult process. This project deals with an advanced wireless notice board. The main objective of this project is to develop a wireless notice board that displays messages sent from the user’s side. When a user sends a message from our website, it is received by a SIM loaded GSM modem at the receiver unit.

2. Software Requirements Specification ( SRS )i.) Introduction - This Application provides facility to sending message

from anywhere without internet or message sending from GSM modem.

Presently almost all electronic notice boards are designed using wired system. One of the drawbacks of the design is the system is inflexible in term of placement. The common notice board cannot be placed anywhere because of the messy wire. The aim of this project is to develop a wireless notice board that will be used at the faculty in order to display latest information.  

ii.) Purpose- This wireless notice board project mainly focuses on transmission of textual data through air interface by the use of GSM through asynchronous serial communication. The data will be processed by the microcontroller on both ends. The data will be displayed on LCD.

Actually what happens is, sending SMS through phone has become very popular and if we can use this SMS to control devices and in displaying data. It is possible to receive or decode the SMS globally by using GSM, by the any part of world we can control and display data on LCD board.

iii.) Scope - The main intention of this project is to display the latest information on the notice board through an android application device by entering the updated information to display on electronic notice board with wireless technology.

The scrolling display board is a common display today for shopping malls, railway stations, colleges, etc., for effective mode of providing information for the people, but this is not easy for updating the messages instantly. This system is enhanced to display the latest information through an Android application of smart/ tablet phones.

iv.) Definitions, Acronyms and Abbreviations : Admin (Administrator): He/she has the authority to add, delete

and update users. J2EE (Java 2 Enterprise Edition): It is a programming

platform, belonging to the Java platform, HTTP (Hyper Text Transfer Protocol): It is a service protocol. JSP (Java Server Pages): It is used to content dynamic web

content. Servlet page (which is used in the background of processing

like submitting.)

v.) Overview: Existing User

Manually Registration.

Drawbacks

Drivers are database dependent, as different database

vendors use wildly different (and usually proprietary)

network protocols.

Not all users can access an application. People who don’t have knowledge of computer can’t use

the system.

Proposed System Registration for faculty. This can also be used for surveillance in corporate

campuses and industries.

Our Plan Registration for faculty members. Project is based on android app.

3. Overall Descriptioni.) Product Perspective - This software is totally self contained and

works relatively as efficient as other packages related to the subject. It provides simple database rather than complex ones for high requirements and it provides good and easy graphical user interface to both new, naive as well as experienced users of the computers.

ii.) Software Requirements – Client on Internet Web Browser, OS (any) Android Web.HTML Interpreter Google Chrome 6.0, I.E., Mozilla Firefox Web Server WASCE, OS (any)Database Server Apache Tomcat OS (any)Development End RAD (J2EE, JAVA, Servlets,

HTML, XML, AJAX), DB2, OS (Windows), WebSphere

iii.) Hardware Requirements - RAM 256 MB Processor Pentium (R) Dual-Core CPU 1.30 GHz

Android Based Device. (More than 4.0 version).

iv.) Software Interface –

Back-End Description : My SQL Database Administrator

Front-End Description : The communication establish between admin and employee is done by J2EE.

1) Constraints - Foreign Key Constraints must be followed in MySQL. Login and Password is used for the identification of users. Only registered person will be authorized to use the services. Fields specified as Primary Key must not be empty. The clock speed of server should be almost 1.7 GHz.`

2) Memory Constraints - At least 1GB of RAM is required at the server side for

effective working. MySQL needs at least 114 KB of memory.

3) Operations -Modes of Operation – Admin is a authorized person who manages employees, admin has the power to add/delete user and control them.

4) User Characteristics – User should have a basic knowledge of

operating various hardware devices specified. User has known more about android technology.

Result – This is to conclude that the project that I undertook was worked upon with a

sincere effort. Most of the requirements have been fulfilled up to the mark and the

requirements which have been remaining, can be completed with a short extension.

The project made here is just to ensure that this product could be valid in today real

challenging world. Here all the facilities are made and tested. Currently the system

works for limited number of administrators to work. In near future it will be

extended for many types of insurance policies so that efficiency can be improved.
