Directional antennas concentrate the transmitted power into a specified direction and form a directional beam pointing to a receiver. Directional communication can bring benefits in terms of power consumption, spatial reuse and security. Using direction antennas implies the transmitters must know the directions of receivers. In this paper, we propose an(More)
In a hostile environment, it is important for a transmitter to make its wireless transmission invisible to adversaries because an adversary can detect the transmitter if the received power at its antennas is strong enough. This paper defines a detection probability model to compute the level of a transmitter being detected by a detection system at arbitrary(More)
