Instant Messaging
Instant messaging (IM) is a form of online communication that
allows real-time interaction through personal computers or mobile
computing devices.
Users can exchange messages privately, similar to e-mail, or join group
conversations
The interactive nature of IM is closer to spoken conversation thanwritten correspondence, allowing users to communicate in a manner
that e-mail does not.

Large and growing number of teens- todays and tommorrows
college students are the regular users of IM,both as personal
communication tool and for educational initiatives in high school.
As IM matures into an accepted means of communication and larger
number of Students arrives on campus as IM users.
Some institution library have set up an online reference desks with IM
applications and faculty have begun using the technology to facilitate office
hours.
Whos Doing it?

How Does it Work?
Functionality ranges widely for IM applicatioins but typically users log into
service with a screen name or ID.
Most IM applications notify users when others join or leave and many
allow users to indiacate their status.
Once logged in, you can send messages to individuals or join IMsessions.Most IM Windows include an area where messages can be displayed
chronologically and a composition box where messages are typed.

Why is it Significant?
Hundereds of millions of people use IM to stay connected.IM epitomizes
the notion of multitasking student,sending and receiving messages at all
hours from a wide range of spectrum devices.
For many students technology has become ingrained in daily life as
telephones are for older generations.
Many colleges and universities are working to incorporate IM into the
eucational aspects of students lives,rather than relegating into a social
function.

Where is it Going?
The introduction of new consumer electronic devices and the growing
functionality of existing ones are broadening the scope of IM avialability.
Video chat applications are appearing,and IM networks are starting to allow
users to send messages to users who are not online and to see archived transcripts
of past messages.
New features are being added to allow richer conversations such as turn
taking,Collaboraive composition, and game playing.

What are the implications ofteaching and learning
Students who use IM feel connected with peers and faculty and some
users have found that IM fecilitates semiformal distance relationships that
are difficult to create through media.
IM offers a higher education a new mode of communication, often for
relatively a low cost and without significant overhead for IT infrastructure.
IM expecting the technology to be their part of their educational lives.in
addition with IM used in many corporations hence its will extend beyond
college.

The Technology
Presence is becoming a key issue in the wired and wireless world. At the
most basic level, presence awareness lets users know when other people in
their contact list are online.
The concept has expanded from the initial online/offline description to
what we identify as rich presence. Thus, presence information can include
more user details.
A general notion of presence would answer the questions of Who(user), Where (location and device), When (preference and willingness),
How, (device capability) and Why (information exchange, leisure,
keeping in touch etc) .

ContinuedAll widely used desktop IM applications like MSN Messenger, Yahoo!
Messenger and Jabber have the following basic features and some includemore advanced communication capabilities, like voice chat and file exchange:
Contact list management - Allows users to create lists of friends and
colleagues and organize them into groups, in order to be able to see their
presence information and contact them directly.
Person to person communication - is achieved through sending and
receiving instant messages. Usually messages can also be sent to users who
are offline, for later retrieval.
User database search - Users can search through a directory to find
others according to interests and profile

SMS, using specified commands and codes to organise contact lists and
send instant messages
Major desktop IM providers have already formed partnerships with
wireless carriers to add SMS (Short Message Services) functionality to
their systems.
Currently IM is also implemented on mobile phones through WAP-based clientand also as a separate Java application for Java enabled mobile phones.
Presence is the key feature that differentiates wireless Instant Messaging to
the existing SMS messaging facility on mobile phones. Without presence, the
user does not know of a persons availability or device status.

ApplicationsMobile messaging standards(SMS - EMS- MMS)
Messaging on mobile phones is rapidly evolving from pure text messages
(SMS) to messages that resemble multimedia presentations (MMS
Multimedia Messaging Service) and can include graphics, data, animations,
audio clips, voice transmissions and short video sequences.
In between SMS and MMS we have the Enhanced Messaging Service(EMS), which can contain combinations of text, simple images and
melodies. The text of an EMS message can be formatted.
While IM has already been combined with SMS, it will be more
successful and easy to use when we will have persistent always oninternet connectivity on mobile phones.

Java application development
Sun Microsystems Java technology on mobile phones is at an
introduction phase, at least in Europe.
In Japan, however, Java has successfully been deployed on i-mode
platform. Interactive content on i-mode is more advanced and graphically
interesting than most mobile content available in Europe (e.g. users can
send full color animated messages with cartoon characters).
The J2ME (J ava2 Platform, Micro Edition, 2001) technology is a drivingforce for content development on mobile phones, personal digital assistants
and other handheld devices.

Other constraints
Privacy concerns
-As presence technology becomes more ubiquitous, personal information canbe accessed by others at any time, bringing not only a sense of being
connected, but new possibilities of surveillance as well.
-By observing the activity that takes place on contact lists, people can
understand their contacts daily routines (e.g. arrival at work, being away
from the desk etc).
-Although basic IM systems allow users to become invisible to others or toblock communication from certain users, more advanced presence
management systems will be required, particularly as IM moves gradually to
the wireless domain.

Security
Security is also a very important factor, particularly for business use of
IM. Major desktop IM services (AOL, Yahoo, MSN etc) have proved to be
unsuitable for corporate environments because of their centralized server
architecture.
Sensitive data can be exposed and there are virus risks as well. The issues
in security involve client to client encryption, client to server and server to
server encryption.
Separate enterprise solutions are common practice to ensure security in
professional settings.

Usability
Handheld devices have limited text input and display capabilities. For
wireless IM, this means a lot of menu navigating and key pressing before
sending an instant message.
mobile phones gradually become more sophisticated, with small
complete keyboards, which have proved to be a convenient input
mechanism for handheld devices.

Example
JabberJabber Project works against incompatibility by providing an open
and extensible IM standard. In early 1998, the Jabber project with the
simple hope of a cross platform IM system.
Today, Jabber is a set of open, XML-based protocols for which there
exist multiple implementations. Jabber compliant servers and clients
provide instant messaging and presence services on thousands of
domains worldwide.
The Jabber platform is free, open source and unlike major IM solutions
that depend on a centralized server, Jabber employs a distributed server
architecture.

Future work
Wireless IM and Presence can be useful for Higher and Further Educationin assisting group communication and collaboration, much like desktop IM
has already done. Little research has been carried out in this new field.
We are still uncertain about how exactly the industry will be formed in the
future and when the interoperability issue will be resolved.
The future of wireless IM and Presence depends upon the establishment and
general acceptance of standards for the exchange of presence information and
instant messages between different service providers, networks and devices.
The open source community through the Jabber project and the newly
formed working group and we can expect many significant applications of
this technology in the near future.

Conclusion
Wireless presence and Instant Messaging are clearly very promising and
have already attracted a great interest.
The gradual establishment of the third generation of mobile network
technology will facilitate persistent always-on connection with friends,
family and colleagues through IM.
Presence is becoming increasingly important and currently moving
beyond IM to a variety of domains.
Hence the emergence of innovative applications on mobile phones based
on presence, including information and location based services,
entertainment applications and multiplayer games.
