Abstract
In this letter, we investigate the bit error rate (BER) performance of a cooperative relaying transmission scheme for wireless nanosensor networks in the Terahertz (THz) Band. We consider nanosensor networks comprising several graphene-based devices deployed at the nanoscale. Both amplify-and-forward (AF) and decode-and-forward (DF) relaying modes are studied. We consider a line-of-sight (LOS) channel model in the THz band which takes into account both spreading loss and molecular absorption loss. Given the high path loss and level of noise from significant random fluctuations through the THz channel, relay assisted schemes offer advantages in terms of significant performance improvements. To quantify the likely benefits, we derive the predicted bit error rate (BER) of the proposed scheme. We conduct a simulation of the proposed relay schemes based on the THz LOS channel model utilizing a Monte-Carlo method. The results obtained show that a performance improvement of 2.2 dB for AF and of 5 dB for DF is achievable at a target bit error rate (BER) of 10-5.
