Introduction to Mobile Internet Protocol PPT Presentation:
Mobile internet is the most common and widely used all over the world. This document helps us to understand the mobile internet protocol in detail. While studying mobile internet protocol we will go through following topics.
a.) WIRLESS TECHNOLOGY BECOMING HOTTER
b.) TRANSACTION TOWARD MOBILITY OVER PAST 20 YEARS
c.) CISCO IOS HAS INTEGRATED NEW TECHNOLOGIES ON MOBILE IP WHICH PROVIDES USER THE FREEDOM TO ROAM
d.) NETWORK MOBILITY IS PROVIDED BY MOBILE IP
Let us learn something about Mobile IP. Mobile IP routing is based on the IP address which is stationary in IP Networks. This enables user to retain its IP address while roaming. Retaining it own mobile IP was made possible and this helped the node to change its IP address while roaming.
The protocols used for mobile IP are.
a.) AGENT DISCOVERY
To take care of address there are two methods used foreign acre of address and collated care of address. Let us have a look at the message format used for this protocol. Type, length, data are the most important component used in transfer of the data. The mobile IP works in the following way agent discovery, registration, and tunneling. Agent discovery contains advertisement and solicitation. Tunneling contains general tunneling, packet forwarding, and reverse tunneling. General tunneling takes place from source to encapsulation and from encapsulation to decapsulation to destination. To send data between mobile node and home node there is need of authentication. Hash based authentication is also been supported by mobile.
Let us now learn the IP version used for transfer of data. IPv4 is used for data transfer in mobile. The drawbacks of using IPv4 are inefficient routing, security issues, ingress filtering, and competition with other protocol, triangular routing, and congestion. To overcome these drawbacks IPv6 provided protecting loss of data packets, routing optimization, security, source routing.
