Research And Realization Of Fast Handoff In Mobile IPv6

With the fast prevalence of Internet, the wide employment of notebook computers and the development of wireless communication devices, users demand the mobility of hosts, i.e., they expect that the hosts can change their locations continuously without interrupting current communication sessions. Therefore IETF defines Mobile IP protocol specifications and relevant technical standards.Each mobile node (MN) has two addresses, home address and care-of address to representing its identity and current position. Mobile IP routing mechanism provides a solution for MN to connect to any links with a permanent IP address on the global Internet. Currently, the researches mainly focus on how to guarantee the communication continuity, how to reduce the handoff delay, how to assure smooth handoff and how to provide the QoS during MIP handoff process.Firstly this thesis introduces MIPv4 and MIPv6, and analysis the...
