“…In [20], [21] the impact of transposition errors for diffusion-based MC with mobile transmit and receive nano-machines is investigated. Different techniques for mitigating transposition errors are considered in [16], [22]- [26]. These approaches can be divided into three categories: Sender-oriented, environment-oriented, and receiver-oriented.…”

In this work, we consider diffusion-based molecular communication with and without drift between two static nanomachines. We employ type-based information encoding, releasing a single molecule per information bit. At the receiver, we consider an asynchronous detection algorithm which exploits the arrival order of the molecules. In such systems, transposition errors fundamentally undermine reliability and capacity. Thus, in this work we study the impact of transpositions on the system performance. Towards this, we present an analytical expression for the exact bit error probability (BEP) caused by transpositions and derive computationally tractable approximations of the BEP for diffusion-based channels with and without drift. Based on these results, we analyze the BEP when background is not negligible and derive the optimal bit interval that minimizes the BEP. Simulation results confirm the theoretical results and show the error and goodput performance for different parameters such as block size or noise generation rate.

“…Popular among these molecular modulation techniques are the Concentration Shift Keying (CSK) and Molecule Shift Keying (MoSK) [19], and Frequency Shift Keying [50]. Other notable works in terms of sequential transmission can be found in [51], [52]. However, the approach to the actual implementation of these techniques has received little attention.…”

The aim of molecular communication (MC) is to develop communication systems for biochemical information interchange among nano devices. While there have been research efforts to model, design and analyze various MC network and devices, a lot still have to be done before we can develop and deploy such systems. Following the traditional physical layered architecture of communication networks, this paper presents design initiatives, open research issues and proffer suggestion towards modeling and designing diffusion-based MC devices.Specifically, we present biologically inspired modular theoretical design approach to modeling and designing MC devices. We also discussed various issues that should be considered in developing an accurate system-theoretic model of an MC system.

“…Then we use Fig. 5 to illustrate the 50% bandwith and acquisition time in (24) and (25), respectively. Where t lef t is determined by the time occurred at 50% magnitude of the first peak h e (x, t), which leaves from zero magnitude; while t right is the time occurred at the 50% magnitude of the last peak returning to zero.…”

“…The information capacity of the relay channel in molecular communication system is analyzed in [23]. In [24], some transmission strategies for molecular communications channel are proposed based on in-sequence delivery of molecules. In [25] and [26], the molecular channel capacity is derived in an information theoretical approach and some necessary techniques for future nano-networks are also explored.…”

Molecular communication has been considered as an emerging technology for both scientific and engineering interests, due to molecular biology and the need of nano-scale communication and computation systems. Molecular communication systems are widely analogue to electrical communication systems involving emitting molecules, diffused propagation of molecules, and reception of molecules, under stochastic characteristics of relatively slow propagation speed and short transmission range. To facilitate large-scale molecular information systems for the purpose of communication and computation, state-ofthe-art explorations are generally assumed perfect alignment of timing among molecular devices and sub-systems. To reach synchronous condition in electronics, phase locked loop (PLL)is known to align timing or phase of waveforms. We extend PLL into molecular PLL (MPLL) consisting of basic elements as molecular phase detector, molecular loop filter, and molecular voltage controlled oscillator. Due to stochastic nature of molecular diffusion, we further analyze MPLL in terms of the diffusion jitter, displacement, and the (particle or molecular) counting noise. Simulations verify such MPLL concept model, tracking performance, and robustness in operation.
