Model As in [16], in this study, we use the switched beam antenna system which consists of …

… with a directional antenna with beam-width θ = π/2. The objective of the directional antenna
… sensor devices which are equipped with directional antennas with beam-width θ ∈ [0, 2π] …

… with a directional antenna with beam-width θ = π/2. The objective of the Directional Antenna
… is to determine an orientation of the antennas with a minimum transmission power range r = …

… We now turn to the case of a ‘steerable’ directional antenna, one whose beam-direction and
beam-width can both be varied. Of course, such variation, as before, could cause changes …

… antenna beam can be supported for each session in which a node participates; thus the use
of directional antennas … , without changing the width or direction of the beam.On the other …

… For the whole high-speed rail, we use the same type of transmitting antenna with 65 o
horizontal and 6.8 o vertical beam widths. The nominal antenna pattern is shown in Fig. 2, though …

… Each node is equipped with the same directional antennas, which have the same beam
width θ (generally less than π). We also take the side lobe and back lobe of the …

… that applies multibeam directional antennas to controlling … we assume antenna patterns
