Abstract: This paper proposes a build-up scheme for large scale heterogeneous mobile Ad hoc networks where a hierarchical architecture with multi-frequency is preferred.Optimized and combined operations of clustering，IPv6 address autoconfiguration，routing and mobility management are proposed to reduce the control overhead and improve the scalability of the networks.Simulation results demonstrate that the scheme improves the efficiency and performance of the organization of heterogeneous Ad hoc networks and supports nodes’ group mobility well.

Key words: Ad hoc networks, hierarchical, IPv6 autoconfiguration, routing, mobility management
