Description

Its a Network Application based onClient/Server Architecture for RemoteMonitoring with the aid of mostcommonly used hand held device i.e.Cell Phone.

Mobile Application will interact with themobile camera and take snapshots atusers will. At the same time theapplication will establish connection

with the Server using GPRS or EDGE

Description

The current image uploaded to webserver and stored in database, nowcan be viewed on any otherGPRS/EDGE enabled cell phonerunning our Receiver MobileApplication.

Motivation

The idea is to build an applicationthat would monitor any remote

location without the constraints ofthe following.

Wired system of Devices.

Specified Region/Boundary.Higher Cost of Implementation.


7/50

Solution

Wireless Device Cell Phone is the most commonly

used and easily available WirelessDevice.

No Boundary limit Once uploaded to the Web Server ,

images/snapshots of the distantlocation would be easily accessible

via Internet.


8/50

Solution

Cost Efficient Implementation Our Mobile Sender Application will

turn a simple mobile camera intoSurveillance Camera and upload thecurrent images with the aid ofGPRS/EDGE without requiring any

additional Hardware.


9/50

Solution

Our project comprises of two mobileapplications run separately on two

cell phones and a Serverapplication runs on Web Server.

Both Mobile applications connect

with Server application to performtheir respective functions.

Major Concepts Of TheProject


11/50

GPRS (General PacketRadio Service)

2.5G Cellular Communication (GSM).Packet Oriented Mobile data service.

a best-effort packet switchedservice.Data rates of 56-114 Kbit/s.Supports WAP (Wireless Application

Protocol)WAP enables access to Mobile Web.GPRS data transfer is typically

charged per megabyte of traffic

12/50

GPRS (General PacketRadio Service)

It provides moderate speed datatransfer, by using unused

time division multiple access(TDMA) channels in the GSMsystem.

WhenTCP/IP is used, each phone

can have one or more IP addressesallocated.

TCP handles any packet loss (e.g.

due to a radio noise induced

EDGE (Enhanced Datarates for GSM Evolution)

It is an upgrade that provides morethan three-fold increase in both the

capacity and performance ofGSM/GPRS networks.In addition to

Gaussian minimum-shift keying

(GMSK), EDGE useshigher-order PSK/8 phase shift keying(8PSK).

MIDP (Mobile InformationDevice Profile)

A specification published for the useofJava on embedded devices such

as mobile phones and PDAsMIDP is part of theJava Platform, Micro Edition (JavaME) framework

There are several different ways tocreate MIDP applications.Code can be written in a plain

text editor.

17/50

MIDlet

An application that conforms to theMIDP standard.

Typically implemented on a Java-enabled cell phone or other

embedded device or emulatorUnlike aJava applet, a MIDlet is

limited to use of the LCDUIThe main class needs to be a

subclass of

javax.microedition.midlet.MIDlet

18/50

Mobile Media API(MMAPI)

Embedding multimedia capabilitiesin a MIDlet.

Java Specification Requests (JSR) 135Play different formats of audio and

video files from the network, arecord store, or a Java Archive (JAR)

file.Capture audio and video and take

snapshots.

Different device manufactures


19/50

Mobile Media API(MMAPI)

Allow you to access media over HTTPand play the WAV file format for

audio and MP3 for video.All devices can be queried todiscover their capabilities.


20/50

Servlet

A servlet is a Java programminglanguage class used to extend the

capabilities of servers.Host applications accessed via arequest-response programmingmodel.

Java Servlet technology definesHTTP-specific servlet classes forapplications hosted by Web

servers.


21/50

Servlet

The Basic Servlet Architecture orLife Cycle


22/50

Servlet Container

A specialized web server thatsupports servlet execution.

The ability to automatically translatespecific URLs into servlet requests.

Servlets are registered with a servletcontainer.

Also referred to as webcontainers or web engines.

Our Server Application uses Tomcatas servlet container.


23/50

Hyper Text Transfer

Protocol


24/50

Overview

Core of our project.An application-level TCP/IP based

protocol.Deliver virtually all files and otherdata, collectively called resources,on the World Wide Web.

A browser works as an HTTP client.Sends requests to an HTTP server

which is called Web server.

Port for HTTP servers to listen on is


25/50

Overview

HTTP is connectionless.HTTP is media independent.

HTTP is stateless.


26/50

Message Format

HTTP uses the client-server model.An HTTP client opens a connection

and sends a request message to anHTTP server.The server then returns a response

message, usually containing the

resource.The format of the request and

response messages is similar.

Structure of Message:


27/50

Message Format

Zero or more header lines CRLF

A blank line i.e.. a CRLF

An optional message body like file,query data or query output.


28/50

Methods()

The GET Method.Client application.

The GET method means retrieveinformation.

Identified by the Request-URI.

Request-URI refers to a data-producing

process.Produced data shall be returned as the

entity in the response.

The GET method can also be used to


29/50

Methods()

Entire form submission can beencapsulated in one URL.

You can access the CGI or Servletprogram with a query.

Fully includes it in the URL.

Example:

http://myhost.com/mypath/myscript.cgi?name1=value1&name2=value2.


30/50

Methods()

The POST MethodClient Application.

A POST request is used to send data to

the server to be processed byServlet.

A block of data sent with the request,

in the message body.Extra headers like Content-Type: and

Content-Length:

The request URI is not a resource to

retrieve.


31/50

Methods()

The HTTP response is normallyprogram output, not a static file.

Query length can be unlimited (unlikein GET)

Can send entire files using post.

Form data is attached to the end of

the POST request (as opposed to theURL).

Not as quick and easy as using GET,but more versatile.


32/50

Methods()

The doGet MethodServer application.

Performs the HTTP GET operation.

Overriding this method to support theGET operation also automaticallysupports the HEAD operation.

Set entity headers in the response.Access the writer or output stream.

Write any response data.


33/50

Methods()

Include content type, and encoding.

Headers before the response data.

May include Data retrieval fromdatabase.

Parameters:req - HttpServletRequest that

encapsulates the request to the servlet.resp - HttpServletResponse that

encapsulates the response from theservlet.


34/50

Methods()

The doPost methodServer application.

Performs the HTTP POST operation.

Read any data from the request (forexample, form parameters).

May include storing data in Database.

Set entity headers in the response.

Access the writer or output stream.

Write any response.


35/50

Methods()

Parameters:req - HttpServletRequest that

encapsulates the request to the servlet.

resp - HttpServletResponse thatencapsulates the response from theservlet.
