The ability to move and hover has made rotary-wing Unmanned Aerial Vehicles (UAVs) excellent platforms to act as Flying Communications Relays (FCR). The problem is the limited amount of time that these UAVs can remain in the air, as they usually depend on batteries that can be drained quickly. In this letter we propose Energy-aware RElay Positioning (EREP), an algorithm for positioning the FCR taking into account its energy consumption. The EREP algorithm is evaluated using simulations. The obtained results show significant gains in the FCR lifetime.
