How to implement Anycast service in mobile IP network

In this paper, a new kind of Anycast communication model in mobile IP network is proposed. This model can use two types of measurement units to dynamically select the optimal Anycst member according to the current status of network congestion, achieves dynamic Anycast group with allowing Anycast members to freely leave and join Anycast group, and solves the existing scalability problem. In addition, this model accomplishes the distributed maintenance and transaction of information on Anycast mobile members. This paper deeply analyzes and discusses the feasibility and validity of this communication model, and the experimental data in the IPv6 simulation demonstrate that the TRT of Anycast service acquired through this communication model is shorter than the one through the current mobile IP communication model.
