Abstract: At the present time, the issue of how to perform Anycast service in Ad Hoc network has attracted more attendon. This paper proposed an Anycast communication model in Ad Hoc network which has been implemented in the simulation network. This model creates a new kind of IPv6 address autoonfiguration scheme which does not need detection of address duplication. In addition, in this model when an Anycast mobile member switches between different sulrnets it does not need to register its carcof address and to build a tunnel to transfer data. This paper deeply discussed and analyzed the model and the experimental data proved its validity and efficiency.
