“…Zhang and Li [16] derive analytical expressions for the number of slots required to discover all the neighbors while taking the collision effect (i.e., two or more neighbors are in the same beam) into account. Olcer et al [17] propose a neighbor scanning strategy to reduce the discovery time by eliminating the unlikely sector scans based on the node position. An et al [18], [19] develop analytical frameworks to investigate the neighbor discovery performance through two theoretical models: one-way neighbor discovery and handshake-based neighbor discovery.…”

A 60 GHz radio is an attractive technology in wireless home networks because it can provide high data rate up to a few Gbps. A 60 GHz network generally uses directional antennas and has a problem of neighbor discovery even though it has an advantage of high data transmissions. In particular, if a directional antenna is used in self-organized wireless adhoc networks, the neighbor discovery time and energy consumption can be significantly increased. To solve this problem, we propose a multi-band directional neighbor discovery scheme, in which management procedures are carried out by using the 2.4 GHz band with the omni-directional antennas whereas data transmissions are performed by using the 60 GHz band with directional antennas. Analytical models on the neighbor discovery time and energy consumption are also derived by considering assisted and beamforming periods in the neighbor discovery procedure through the omni-directional antenna and directional antenna. Performance evaluation results demonstrate that the proposed scheme outperforms comparative schemes that use only directional beamforming in terms of the average neighbor discovery time and energy consumption.Index Terms-Directional antennas, mmWave ad-hoc networks, multi-band application, neighbor discovery, selforganization.0018-9545 (c)

“…To cope with the attenuation problem, directional antennas with high directive gains can be utilized. In [19] [20], smart directional neighbor scanning strategies are proposed to reduce the directional neighbor discovery time in indoor networks at mmWave frequence. In [21], the deafness and hidden node problem is discussed for short range transmission limitations due to large propagation losses and reduced diffraction around obstacles with directional antennas over the mmWave frequency band.…”

The relation of multicast transmission and directional antennas is an open problem that has been debated for a long period of time. In this paper, we propose a group-aware multicast scheme of efficient multicast communication using the directional antennas for 60GHz millimeter wave wireless networks. For this purpose, we first derive the relation among beamwidth, distance between devices and most suitable data rate in the 60GHz frequency-based wireless network. In addition, for the dynamic beamforming of multicast communication, the x and y coordinates of any point with sender device at the center is generated, and a best-chosen group is deduced based on the Euclidean distance. Then the most suitable data rate for the group is obtained using the law of cosine. Using the Standard IEEE 802.11ad MAC protocol as an example, extensive simulation results demonstrate that the proposed scheme outperforms the existing multicast communication schemes with directional antennas under different situations.
