In recent years, multi-unmanned aerial vehicle (UAV) systems have been an active research area. Coverage problem is a basic task in multi unmanned aerial vehicles (UAVs). As UAVs are nowadays widely used in many application areas, the research in the coverage control has become a hot point. In this paper, we present a survey of the most works in this area, classifying the types of these works and describing the main contributions in their works.

Multiple unmanned multirotor (MUM) systems are becoming a reality. They have a wide range of applications such as for surveillance, search and rescue, monitoring operations in hazardous environments and providing communication coverage services. Currently, an important issue in MUM is coverage control. In this paper, an existing coverage control algorithm has been extended to incorporate a new sensor model, which is downward facing and allows pan-tilt-zoom (PTZ). Two new constraints, namely view angle and collision avoidance, have also been included. Mobile network coverage among the MUMs is studied. Finally, the proposed scheme is tested in computer simulations.
