Abstract: This paper proposes the implementation scheme and the key technology improvement of MIPv6 protocol based on Linux Adhoc network.Through the analysis on the problem of mobile switching delay,the proposal reduces the system delay.Through the establishment of experimental scenes,the performance of the mobile switching is studied.Comparison of the delay data verifies the improved scheme is correct and feasible.

Key words: Adhoc network, MIPv6, Dual NIC technology, Linux
