Enhancement and performance analysis of channel access mechanisms in Terahertz band

With Terahertz band (0.1–10 THz) technology, several nanoscale ad hoc applications could be developed, such as intrabody health monitoring, programmable material, etc. The fundamental element to ensure the functionality of these is way access radio communication channel. main challenge with nanocommunication need efficiently share terahertz spectrum optimize data transmission in nanonetworks. In this context, Spread Time On-Off Keying (TS-OOK) protocol was proposed a channel mechanism that uses Femtosecond-Long pulse-based OOK modulation. Furthermore, different new improvements TS-OOK were introduced, RD-TSOOK and SRH-TSOOK approaches. paper, we review compare OOK-based techniques our approach called SDMA-TSOOK. design scheme takes into account weaknesses mechanisms terms balancing, co-channel collision, networking capacity pose problem for concurrent access. We evaluate performance using BitSimulator. obtained results showed SDMA-TSOOK ensures 100% equitable between nanodevices, well better success rate an insignificant number collisions compared published reference protocols.
