THz communication exhibits an extremely large bandwidth (tens to hundreds of GHz) at the cost of a very high path loss (>100 dB for distances beyond a few meters). Therefore, highly directional antennas (DAs) are needed simultaneously in transmission and reception all the time to establish reliable communication links. The application of highly DAs introduces new challenges when moving up in the protocol stack. In this thesis, new protocols for ultra-broadband networks in the THz band are presented, by following a bottom up approach (from data link layer to network layer). First, an open source network simulation platform for THz communication networks, TeraSim, is introduced. Second, a link-layer synchronization and medium access control (MAC) protocol for very-high-speed THz wireless communication networks is presented. Third, a time-efficient neighbor discovery protocol for THz-band communication networks is introduced. The fundamental idea in the protocol is to expedite the neighbor discovery process by leveraging the full antenna radiation pattern. Then, multi-hop relaying strategy for THz-band communication networks is introduced to study the relaying distance that maximizes the network throughput by considering cross-layer effects. Finally, an adaptive routing protocol for highly dynamic buffer-limited directional terahertz communication networks is presented.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
