… studied the multihop connectivity of networks with directional antennas. Specifically we have
focused on random beamforming strategies where nodes choose the direction of radiation …

… backbone of the network. These links are set up by highgain directional antennas mounted
on top … Typically, a subset of network nodes (called gateways) have direct connectivity to the …

… After laying out the modeling assumptions in the next section, in Section 3 we consider
the notion of threshold range for k-connectivity in the context of directional antennas. In the …

… In Sections I11 and IV we describe the multihop network environment and the new protocols
… angles of the directional antennas are presented in Section V. A network design example is …

… Detailed wireless network simulations also show that this … of multihop flows relative to using
omni-directional antennas. … of the mesh network with multiple directional antennas and orient …
