ADAPT: An Adaptive Directional Antenna Protocol for medium access control in Terahertz communication networks

Terahertz (THz)-band (0.1–10 THz) communication is envisioned as a key technology for the next generation of wireless communications, with potential to enable Terabit-per-second (Tbps) links. To overcome high path loss this band, use directional antennas on both transmitter and receiver necessary even distances few meters. This paper presents an Adaptive Directional Antenna Protocol THz networks (ADAPT), novel medium access control (MAC) protocol tailored ultra-high-speed in centralized architecture. An point turning antenna divides space sectors, synchronization achieved 3-way receiver-initiated handshake. The implements adaptive sector time modulation mechanisms. analytical model study stability condition achievable throughput presented. performance ADAPT investigated extensive simulations ns-3 terms discard rate, using physical layer defined IEEE 802.15.3d, first standard communications. Results show that proposed solution improves current protocols achieves excess 100 Gigabit-per-second (Gbps), while reducing latency packet rate.
