Considerable efforts are being made in the area of interactive satellite broadcast services to mobiles, which range from the development of specific communication standards to the realization of practical proof-of-concept prototypes. The main reasons for such a big interest lie in the fact that interactive satellite services are a large potential market with many possible applications. Frequent and long-lasting shadowing caused by surrounding buildings in urban and suburban scenarios greatly limits system availability. The common approach to solve the problem consists in deploying fixed gap fillers, which imply a great consumption of economic and bandwidth resources. In the present paper we propose a novel hybrid satellite-terrestrial system architecture in which cooperative communication techniques are extensively adopted in order to reduce the number of gap-fillers needed to get a target system availability. Nodes are meant to have both networking and satellite communication capabilities so that each of them can possibly act as a Mobile Gap-Filler (MGF).
