Terahertz band (0.1–10 THz) nanocommunications are expected to have a plethora of biomedical, industrial, and military applications. A pulse‐based modulation scheme could enable communications among nano‐devices. Nevertheless, synchronisation could be a significant performance limiting factor and an arduous task to accomplish considering the huge bandwidth of the transmitted pulse, and the simple design and energy constraint requirements of the nano‐transceivers. This study proposes a novel synchronisation scheme for pulse‐based nanocommunication based on a continuous‐time moving average (CTMA) algorithm. Since CTMA uses an energy collection approach, it does not increase the energy and complexity requirements of nano‐transceivers. This approach is based on continuously moving sub‐integration windows and searching for the maximum energy over the entire preamble duration. The simulation results showed that using the proposed scheme, for a distance of up to 5 mm, a synchronisation probability of >0.7 was obtained for a signal energy to noise ratio (SNR) of 20 dB. The results showed good performance in terms of the tradeoff among the synchronisation probability, SNR, and distance between nanonodes. Moreover, synchronisation error was also evaluated to check the overall performance of the scheme. Altogether, the proposed scheme makes an appropriate step forward to enable nanocommunication among resource‐constrained nanonetworks.
