“…In this paper, we devise energy-efficient information fusion strategies triggered by the detection of a mobile target, e.g., an Unmanned Aerial Vehicle (UAV). We consider an ELectronic-signals INTelligence (ELINT) scenario, where the event detection is based on the radio signal emitted by the mobile target [12]. Motivated by the recent advances in SubGHz communication technologies, which allow relatively inexpensive wireless devices to communicate at distances of the order of kilometers [13], we first consider a scenario with direct communications between the WSN nodes and the Communication and Control center (C2).…”
