SBN: Simple Block Nanocode for nanocommunications

Nanonetworks consist of nanomachines that perform simple tasks (sensing, data processing and communication) at molecular scale. Nanonetworks promise novel solutions in various fields, such as biomedical, industrial and military. Reliable nanocommunications require error control. ARQ and complex Forward Error Correction (FEC) are not appropriate in nano-devices due to the peculiarities of Terahertz band, limited computation complexity and energy capacity. In this paper we propose Simple Block Nanocode (SBN) to provide reliable data transmission in electromagnetic nanocommunications. We compare it with the two reliable transmission codes in nanonetworks in the literature, minimum energy channel (MEC) and Low Weight Channel (LWC) codes. The results show that SBN outperforms MEC and LWC in terms of reliability and image quality at receiver. The results also show that a nano-device (with nano-camera) with harvesting module has enough energy to support perpetual image transmission.
