Molecular communication with DNA cellular storage system

Abstract

In this paper, we construct a DNA Cellular Storage System (DCSS) that allows rewritable and reliable DNA storage and retrieval. To demonstrate the applicability of our proposed DCSS, we embed it into a molecular communication system and propose a new signal modulation scheme called DNA-molecule shift keying (DNA-MoSK). In our proposed modulation scheme, DNA sequences are used to encode data in molecules, providing higher scalability than other existing modulation schemes, such as concentration shift keying (CSK), molecule shift keying (MoSK), and depleted-molecule shift keying (D-MoSK). Through numerical analyses, we show that the performance of DNA-MoSK is comparable to the performance of D-MoSK which, in turn, performs better than both MoSK and CSK, in terms of the achievable rate (AR) and the symbol error rate (SER). Overall, DNA-MoSK is capable of achieving high channel capacity values, suggesting it as a better modulation technique for high scalability.
