Abstract:

A load-aware time division multiple access (LATDMA) protocol is proposed in this paper, by considering the avoidance of symbol collisions in the time spread on-off keying (TSOOK) based communication system combined with load-unbalanced application scenarios. This protocol adopts a dynamic TDMA-based time slot allocation mechanism according to the current number of source nodes, their corresponding traffic and the transmission peculiarities of Terahertz channel. The simulation results show that LATDMA is energy efficient and gains obvious advantages in average end-to-end delay and average throughput, which proves suitable to support low-delay and load-unbalanced wireless nanosensor networks (WNSNs).

Key words:nanonetworks; Terahertz band; medium access control; load-aware
