Mobile Ip: Technology of Mobile Networking

Description

Mobile IP is a communication protocol that allows the users the move from one network to another while maintaining a permanent IP address. It ensures that the communication will continue without the user's sessions or connections being dropped. It is most often found in wire and wireless environments where users need to carry their mobile devices across multiple LAN subnets. Examples of wire systems are IP over DVB, WLAN, WiMAX and BWA. The Mobile IP allows for location-independent routing of IP datagrams on the internet. Each mobile node is identified by its home address disregarding its current location in the internet. Its home address is associated with the local endpoint of a tunnel to its home agent. Mobile IP specifies how a mobile node registers with its home agent and how the home agent routes data grams to the mobile node through tunnel. Mobile IP is not required within cellular systems such as 3G, to provide transparency when Internet users migrate between cellular towers, since these systems provide their own data link layer handover and roaming mechanisms. However, it is often used in 3G systems to allow seamless IP mobility between different packet data serving node (PDSN) domains. The present book of “Mobile IP Technology of Mobile Networking” consists of all the principles and practices required for the accurate IP address and provides basis for the field of computer engineering.
