Mobile Ad hoc Networks (MANet) are a spontaneous collection of mobile terminals. Each node must collaborate in order to structure information exchange. An hybrid network is a MANet connected to Internet via an Access Point (AP). This paper proposes to organize MANet and hybrid networks through a virtual topology. The paper considers a virtual topology as a hierarchical organization based on the integration of both backbone and clusters. Construction and maintenance procedures of such a virtual topology are detailed and deal with robustness and reliability issues. The paper presents a proactive gratuitous maintenance for the backbone and a new maintenance algorithm for clusters presenting a reduced overhead. Moreover, this improved solution allows integrating multiple APs in hybrid networks, deleting the previous single point of failure.
