Drones are more and more important in emergency response scenarios, where they can be equipped with wireless access points and deployed to configure a recovery ad-hoc flying network, e.g., to interconnect users positioned in a disaster area. Communication between users is allowed by means of multi-hop paths including one or more relay drones. An interesting optimization problem asks for determining the position of a minimum number of drones in order to guarantee that all the required communication paths can be established. Wireless channels are used and interference plays an important role: we propose an interference model and we embed it in a Mixed Integer Linear Programming formulation. Preliminary computational results are presented, showing the proposed model is able to solve instances of medium size in order of minutes.

Abstract
Drones are more and more important in emergency response scenarios, where they can be equipped with wireless access points and deployed to configure a recovery ad-hoc flying network, e.g., to interconnect users positioned in a disaster area. Communication between users is allowed by means of multi-hop paths including one or more relay drones. An interesting optimization problem asks for determining the position of a minimum number of drones in order to guarantee that all the required communication paths can be established. Wireless channels are used and interference plays an important role: we propose an interference model and we embed it in a Mixed Integer Linear Programming formulation. Preliminary computational results are presented, showing the proposed model is able to solve instances of medium size in order of minutes.
