… equipped with a directional antenna for transmission and an omnidirectional antenna for
reception.Similar to [26], we assume that each node’s transmitter has a power control capability. …

… control packets are unnecessarily broadcast in the channel. … directional antennas, we
consider an optimization whereby a node forwards a control packet with only n (n <= N) antenna …

… -gain directional antennas for both transmission and reception in wireless ad hoc networks
[1–10]. Directional antennas provide longer transmission range and higher data rate, and …
