ABSTRACT
The first and only available open-source model of a full stack Terahertz (THz) network called TeraSim is integrated within the ns-3 network simulator. TeraSim currently supports only uplink communication in infrastructure mode, which is sufficient for UDP-based applications. This paper presents an extension to TeraSim for supporting TCP-based data transmission and reception. The implemented extension involves modifications to TeraSim's MAC layer in both the client node and the Access Point (AP) to enable downlink data communication needed for TCP. The extension has been assessed via a simulation campaign that compares the average throughput and AP cycle time when UDP/TCP is employed at the Transport layer. A Transmission Window in the range of 0.25-0.32 THz frequency is considered. The protocol is evaluated for various number of client nodes and Physical layer modulation schemes.
