MANET protocols are often evaluated through simulations, not in a real radio environment. We describe here the implementation and deployment of a complete testbed for hybrid networks, allowing a seamless integration of an ad-hoc network in the Internet. In particular, a self-organization protocol and the mobility management protocol benefiting from this organization were implemented. The performances demonstrate the feasibility and usefulness of this scheme. Besides, this testbed offers a detailed description of the requirements to constitute a wireless testbed and to test any protocol for ad hoc or hybrid networks.
