Performance analysis of power adjustment methods in molecular communication via diffusion

In this paper, performance of binary concentration shift keying (BCSK), BCSK with power adjustment (BCSK-PA), and BCSK with consecutive power adjustment (BCSK-CPA) are analyzed in terms of bit error rate (BER), energy, and memory within the context of molecular communication via diffusion. As the communication environment, vessel-like environment is realized. The results show that BCSK-PA outperforms BCSK and BCSK-CPA in BER and energy analysis. Yet, it is outperformed by BCSK and BCSK-CPA in memory requirements. BCSK-CPA performs between BCSK and BCSK-PA in all three analysis that shows BCSK-CPA is a nice option to have comparatively low BER and energy usage when the system has low memory requirement.
