Mobile Two-Way Molecular Communication via Diffusion Using Amplify-and-Forward and Analog Network Coding

Coding in Diffusion-Based Molecular Nanonetworks: A Comprehensive Survey

“…Consequently, the error probability in absolute terms decreases as the transmission rate decreases. Also, The mobile molecular communication system via diffusion using AF relaying and ANC, adapted from [268]. Half-duplex network coding, analogous to Table 9, is utilized.…”

“…Cheng et al [268] present for the first time a mobile DBMC system. The changing distance between the transmitters leads to time-varying channels [268].…”

“…Cheng et al [268] present for the first time a mobile DBMC system. The changing distance between the transmitters leads to time-varying channels [268]. Two source nanomachines, denoted as S 1 and S 2 , exchange information using the nanorelay R, as illustrated in Fig.…”

“…In the initial feed sand, the relay R is located between the two nodes S 1 and S 2 . In addition, it is assumed that S 1 is not in the transmission range of S 2 and the three nodes are time synchronized [268]. Quaternary MoSK modulation [279] is considered as a baseline modulation scheme.…”

“…At each time step of the simulation, the molecules, node S 1 , node S 2 , and relay R are subject to a random walk. Let ∆t denote the time interval duration, D A,B denote the diffusion coefficients of the molecule types A and B (which are assumed to be equal in [268]). Also, D S1 and D S2 denote the diffusion coefficients of nodes S 1 and S 2 , respectively, and D R denotes the diffusion coefficient of the relay R. The new positions are determined in each coordinate by sampling a random Gaussian variable with mean 0 and the respective standard deviation 2D A,B ∆t, 2D S1 ∆t, 2D S2 ∆t, and √ 2D R ∆t.…”
