Terahertz (THz)-band (0.1-10 THz) communication is envisioned as a potentially key technology to satisfy the need for much higher wireless data rates. The THz-band provides a huge transmission bandwidth, which ranges from hundreds of GHz up to a few THz. Nevertheless, this bandwidth comes at the cost of a very high pass loss, and, as a result, highly directional antennas are needed simultaneously in transmission and reception to establish a communication link beyond a few meters. In directional communication networks, efficient neighbor discovery is needed to overcome the deafness problem. Existing neighbor discovery protocols for lower frequency bands cannot be directly utilized, because they do not capture the peculiarities of the THz band or the need to support multi Giga-bit-per-second and even Tera-bit-per- second links. In this paper, a neighbor discovery protocol for THz- band communication networks that leverages the directional antenna side-lobe information is presented. More specifically, the full antenna radiation pattern is utilized to detect a series of effective signals and map them to a universal detection standard and expedite the neighbor discovery process. A mathematical framework is developed to compare the neighbor discovery protocols with and without the antenna side-lobe information, and numerical results are provided to illustrate the performance of the proposed neighbor discovery protocol in terms of total time needed to complete the discovery process.
