In mobile IP, packets that are sent to a mobile host by the correspondent host are first routed to the mobile host's home agent and then forwarded to the mobile host at its current location by its home agent. However, packets that are sent from the mobile host should not be handled in this way.
The care-of address of a mobile device is the network-native IP address of the device when operating in a foreign network. Home agent A home agent is a router on a mobile node’s home network which tunnels datagrams for delivery to the mobile node when it is away from home. It maintains current location (IP address) information for the mobile ...
Although there are many types of routing protocols, three major classes are in widespread use on IP networks: Interior gateway protocols type 1, link-state routing protocols, such as OSPF and IS-IS; Interior gateway protocols type 2, distance-vector routing protocols, such as Routing Information Protocol, RIPv2, IGRP.
An IP network to which a mobile set can be connected; A set of settings that are used for that connection; A particular option in a set of settings in a mobile phone; When a GPRS mobile phone sets up a PDP context, the access point is selected. At this point an Access Point Name (APN) is determined Example: aricenttechnologies.mnc012.mcc345.gprs
To illustrate the operation of MIH, let us take an example of a real-time gaming application, using DiffServ at the IP layer, being handed over from Mobile-Fi to WiMAX. The application is currently using the Assured Forwarding Class 1, AF1, DiffServ service, and the Class 2 Real-Time Interactive Mobile-Fi service.
An IP packet has no trailer. However, an IP packet is often carried as the payload inside an Ethernet frame, which has its own header and trailer. Per the end-to-end principle , IP networks do not provide guarantees of delivery, non-duplication, or in-order delivery of packets.

The Optimized Link State Routing Protocol (OLSR) [1] is an IP routing protocol optimized for mobile ad hoc networks, which can also be used on other wireless ad hoc networks. OLSR is a proactive link-state routing protocol , which uses hello and topology control (TC) messages to discover and then disseminate link state information throughout ...
