Abstract: This paper proposes an improved Anycast routing scheme in mobile IP network based on Anycast routing protocol in mobile IP. This scheme can make the mobile nodes locating in foreign areas acquire Anycast services with good quality and little response time. It reduces the delay time for obtaining the services and saves the network bandwidth resource. The feasibility of the scheme is analyzed. According to the experimental data in IPv6 simulation, it proves that the scheme is valid and reliable.
