THE ROLE OF INTERNET TECHNOLOGY IN MOBILE DATA SYSTEMS
[attachment=67893]
INTRODUCTION
1. Today, Internet Technology is progressing so fast today that it is revolutionizing
the entire framework of communication technology which had just been a distant dream
till a few decades back. Mobile data systems are basically an extension of the internet
on mobile devices which allow the users to access internet even while they are on
move. It is an integration of telecommunication technologies and internet in such a way
that it provides solutions to all types of communication requirements today. With the
amount of progress which has been achieved in wireless technology, sophisticated
software and hardware design, the way we communicate has changed in quite a major
way.
NEW INTERNET TECHNOLOGY: TRANSITION FROM IPv4 TO IPv6
4. Mobile networks are being designed around IP frameworks by which we mean
using Internet technology to run mobile services. We are standing on the cusp of a huge
update of one of the underlying technologies of the internet – from IPv4 to IPv6. To help
understand what this entire means and the impact of IP on the future of mobile
networks, let us discuss the transition of Internet Technology from IPv4 to IPv6 in
mobile Data systems
IPV6 TECHNOLOGY: OVERVIEW
Mobile IPv6 is standardized much like Mobile IPv4. Mobile IPv6 provides
transparent mobility support for mobile nodes communicating across IPv6 networks. It
shares many of the same features and capabilities as Mobile IPv4 while leveraging the
advantages that the IPv6 protocol itself provides.
Mobile IPv6 Operation
In IPv6, the mobile node is always reachable
regardless of point of attachment. The mobile node registers with a home agent in the
home network whenever it changes point of attachment within foreign networks. While
the binding between the mobile node and home address allows any node corresponding
with the mobile node to continue communication, traffic is routed in a non optimal
manner. Mobile IPv6 resolves this by allowing the correspondent node to participate in
the Mobile IPv6 process. The two nodes (mobile and correspondent) communicate
through two different methods of bidirectional tunneling and route optimization as
explained in succeeding paragraphs
Bidirectional Tunneling Mode
Bidirectional tunneling mode does not
require the correspondent node to support Mobile IPv6. In this mode, traffic is
routed similarly to a reverse tunneling mode in Mobile IPv4. Figure 1 below
illustrates bidirectional tunneling mode in Mobile IPv6. Packets from the mobile
node towards the correspondent node are tunneled to the home agent and then
routed from the home network to the correspondent node. Packets from the
correspondent node are routed to the home agent and then tunneled to the
mobile node. Bidirectional tunneling mode requires IPv6 neighbor discovery
capability in the home agent
Route Optimization Mode
Route optimization mode in Mobile IPv6
allows the IPv6 network to use standard or policy based algorithms to determine
how packets are routed from the correspondent node to the mobile node. This
mode requires the correspondent node to support the Mobile IPv6 protocol.
Figure 2 below illustrates route optimization mode in Mobile IPv6. To populate
the binding’s database on the correspondent node, the mobile node sends
Binding Update messages, similar to those sent to the home agent. The
correspondent node maintains a binding’s database that maps the mobile node’s
home address. Packets from the mobile node towards the correspondent node
are sent directly to the correspondent node. Packets from the correspondent
node are routed directly to the CoA of the mobile node.
carrying Authentication Network Access (PANA).
Network Mobility Basic Support Protocol.
Network Mobility (NEMO)
is an extension of Mobile IPv6 that enables session continuity for all nodes
connected to a mobile network. NEMO introduces the concept of a mobile router,
which is a Mobile IPv6 mobile node that can route traffic that moves with the
router. This allows reach of all nodes behind the mobile router, regardless of their
support for any mobility protocol, as the router changes its point of attachment to
the network. NEMO works by using the bidirectional tunnel mode of Mobile IPv6
to tunnel all traffic between the mobile router and the home agent.
MOBILE INTERNET TECHNOLOGY: MOBILE DATA CONNECTIVITY OVER CELLULAR NETWORK
The Mobile Internet technology refers to Internet content viewable by wireless
mobile devices of which WAP (Wireless Application Protocol) is one, but not the only
example. Popular websites like yahoo.com have carefully been designed their WAP
sites to look and feel much like their wired counterparts, while search engines like
Google are transferring pages from HTML to WML so they can be accessed by wireless
users. Besides WAP, expertise in Mobile Internet technology extends to parallel mobile
technologies like I-mode and J-Phone (dominant in the Asia-Pacific region).
10. Link Mobile Gateways are designed to provide internet/WAN connectivity over a
Cellular Network to 10/100-BaseT Ethernet and/or 802.11 WiFi connected devices.
Remote Video Monitoring for mobile subscribers is provided by this for additional
security of users or sensitive equipments. Various package solutions are provided fornternet connectivity for industrial use as well. Using cellular, these packages are ideal
for situations where individuals who work at multiple locations need access to the web
on a routine basis. Mobile Internet Systems are custom-designed and are built with
rugged components. Each package is built with the subscribers work environment in
mind. Additional elements such as web-enabled video monitoring or sensor monitoring
can be added as needed into this
CONCLUSION
11. Mobile internet technology is the new trend in cell phone users. People prefer to
listen to music, watch videos, send and receive emails and communicate to each other
while they are on the move and to be able to do that they need mobile internet. With so
many people hooked on to the virtual world and the mobile technologies, there is no
doubt that there would still be many more developments in this field. In last decade, the
internet has fundamentally changed the way we work, play and communicate. Evolving
wireless and mobile broadband technologies are now enabling the next major wave to
be called Mobile Internet. The next-generation Mobile Internet will enable consumers
and businesses to connect and access new types of applications and new forms of
information wherever and whenever they want.
12. In the next decade, the expansion of the Mobile Internet Technology is likely to
be the fastest growing marketplace in the telecommunications industry. Mobile Internet
Technology is the next generation evolution which changes the way how we
communicate. The market of mobile users is increasing daily. Today, with millions of
people using the mobile technology, there is a sudden surge to search and develop new
mechanisms to engage the subscribers. This means that the market of mobile is not
limited to providing services pertaining to calling anymore.
13. Advancements in technology have made it possible for a variety of features such
as Internet access, games, cameras etc to be made available on mobile phones. The
advent of multimedia phones, with their slick touch-screen interfaces and a wide array
of innovative features has revolutionized the way mobile applications are done in Mobile
Internet Technology. This has led to an increase in demand for subscriber applications.
Basically, with the help of mobile internet, the computer users can surf the internet,
exchange data from anywhere they like even outside their home
