Paper Accepted: "Diffusive Molecular Communication in a Biological Spherical Environment with Partially Absorbing Boundary"

The paper "Diffusive Molecular Communication in a Biological Spherical Environment with Partially Absorbing Boundary" (link to arXiv version; here is the DOI) was accepted for publication in IEEE Transactions on Communications. We derive the diffusive channel response for a transmitter and receiver that are arbitrarily placed within a partially absorbing spherical shell. This paper was co-authored with Hamidreza Arjmandi and Mohammad Zoofaghari (both at Yazd University, Iran).

Paper Accepted - A Novel A Priori Simulation Algorithm for Absorbing Receivers in Diffusion-Based Molecular Communication Systems

The paper "A Novel A Priori Simulation Algorithm for Absorbing Receivers in Diffusion-Based Molecular Communication Systems" (link to arXiv version; here is the DOI) was accepted for publication in IEEE Transactions on NanoBioscience. We propose a Monte Carlo type approach to efficiently simulate surface absorption in microscopic particle-based simulations. The algorithm is shown to be very accurate when simulating with large time steps. This paper was co-authored with Yiran Wang and Nan Yang (both at ANU, Australia). An implementation of this algorithm is included in the AcCoRD simulator (Actor-based Communication via Reaction-Diffusion).

Paper Accepted - "Channel Modeling for Diffusive Molecular Communication - A Tutorial Review"

The paper "Channel Modeling for Diffusive Molecular Communication - A Tutorial Review" (link to arXiv version; here is the DOI) was accepted for publication in Proceedings of the IEEE. We do an extensive review of the end-to-end communication channel models that are available for diffusive molecular communication systems, as well discuss simulation methods and experimental testbeds. It should be a helpful resource for anyone interested in working in this area, whether you are new to the field or an experienced member. This paper was co-authored with colleagues at FAU (Germany): Vahid Jamali, Arman Ahmadzadeh, Wayan Wicke, and Robert Schober.

Paper Accepted - Symbol-by-Symbol Maximum Likelihood Detection for Cooperative Molecular Communication

The paper "Symbol-by-Symbol Maximum Likelihood Detection for Cooperative Molecular Communication" (link to arXiv version; here is the DOI) was accepted for publication in IEEE Transactions on Communications. We propose different methods of maximum-likelihood-based detection when a fusion centre combines observations of diffusing molecules by a collection of receivers. This paper was co-authored with Yuting Fang (ANU, Australia), Nan Yang (ANU, Australia), Andrew W. Eckford (York, Canada), and Rodney A. Kennedy (ANU, Australia).

Posted to arXiv - On the Analysis of Bacterial Cooperation with a Characterization of 2D Signal Propagation

Our paper "On the Analysis of Bacterial Cooperation with a Characterization of 2D Signal Propagation" was posted to arXiv. This paper derives new results on diffusion with degradation over a 2D environment and applies them to a model for bacteria quorum sensing. We then use approximations to estimate the expected density of cooperating bacteria. The paper was co-authored with Yuting Fang, Nan Yang, and Andrew W. Eckford, and submitted to IEEE ICC 2019.

Tutorial on Molecular Communication at IEEE GLOBECOM

I will be helping to deliver a tutorial on molecular communication at this year's IEEE GLOBECOM in Abu Dhabi, UAE. The full title is "Molecular Communication: Methods, Simulations, and Experiments" It will be presented with Andrew Eckford (York), Yansha Deng (KCL), and Nariman Farsad (Stanford). The tutorial will be held on Sunday, 9 December from 2pm-5:30pm.

Abstract: This tutorial introduces the emerging field of molecular communication wherein chemical signals are used to connect "tiny" machines such as living cells, synthetic biological devices and swarms of micro-scale robots. The tutorial begins with an overview of molecular communication systems and how they are modeled; each has a Transmitter, the Propagation Channel, and the Receiver, just as in a conventional communication system. Specific channel and noise models are presented and the derivation of channel impulse responses is discussed. Signal processing via chemical and genetic circuits is described. An overview and demonstration of specialized simulation tools is provided. The tutorial concludes with a discussion of the recent experimental implementations of molecular communication, and some of the most important open problems in this exciting new area.

My section of the tutorial will be on simulation methods, and will include a demonstration of the AcCoRD simulator.

Posted to arXiv - A Novel A Priori Simulation Algorithm for Absorbing Receivers in Diffusion-Based Molecular Communication Systems

Our paper "A Novel A Priori Simulation Algorithm for Absorbing Receivers in Diffusion-Based Molecular Communication Systems" was posted to arXiv. This paper shows how a Monte Carlo type approach can be used to efficiently simulate surface absorption in microscopic particle-based simulations. Compared with the usual method for simulating microscopic surface absorption, the proposed scheme can speed up simulations by many orders of magnitude with a very small loss in accuracy. The paper was co-authored with Yiran Wang and Nan Yang and submitted for journal publication. An implementation of this algorithm is included in the AcCoRD simulator (Actor-based Communication via Reaction-Diffusion).
