Abstract


With the rapid development of communications and wireless access technologies , mobile host network services become a necessity . Mobile IP protocol is a communication terminal in the movement to ensure the communication connection of the protocol, the protocol can be by the terminal when moving remains an ongoing communication . IPv4 is Mobile IPv6 instead become a new network infrastructure , the tremendous impact of mobile IPv6 will be the development of network technology . The switch mobile IPv6 technology is the core problem . Communication terminal to change the access route , how to reduce the switching delay time and lost insurance rate is the key to the development and popularization of mobile technology in the future . The paper outlines the basic principles of mobile IP technology and achieve goals , and mobile IPv4 and IPv6 protocol is described in detail . Furthermore, the paper analyzes the Mobile IPv6 protocol hierarchical mobile , fast-moving and fast hierarchical mobile three switch extension technology . Lag for fast hierarchical mobile switching persists in mobile handoff latency and packet loss rate can not be further reduced , this paper presents a fast hierarchical mobile technology prediction parameters based on the probability of movement ( PF - HMIP) . Mobile station acts according to its own mobile and mobile location mobile probability forecast parameters and the parameters are sent to the mobile anchor . Mobility anchor point parameter to its management of all mobile domain forwarding destination for the message of the mobile station in accordance with the movement probability forecast . The paper elaborated the principle of the technology , algorithm , message format and the switching process , and pointed out that the technology can further reduce switching packet loss rate and handoff delay . Based on the rapid classification of mobile technology and mobile probability forecast parameters of the three expansion using network simulation software NS2 implementation and completion of the performance verification . Four the technical packet loss rate , switching delay performance comparison , proved the the PF-HMIP technology relative to the hierarchical mobile , fast-moving and fast - hierarchical mobile the three extension technology to further reduce handoff delay . and packet loss rate in the switching process , in order to better adapt to the requirements of the mobile network switch .
