Modeling and Experimental Verification of the Diffusion Channel for Nanonetworking

Advances in the fields of nanotechnology and biotechnology over the last decade show that many applications that were considered to be science-fiction will become feasible in the near future. In particular, the early treatment of nanotechnology in the field of health will provide Turkey with significant opportunities in this new field of science and its applications.

Our goal in this project is to establish the first testbed in the nano-scale in the field of molecular communication between the nanomachines, which is studied only theoretically, and to make the necessary corrections in theoretical models by measuring the characteristics of different transmission channels for close-to-real applications, and also develop a GPU-based simulator. The fact that a similar nano-scale communications testbed does not exist in the literature will seriously highlight our research group, which has already been recognized by our previous scientific studies in the nanonetworking society. Thus, the accumulation of the knowledge and skills obtained through this project will strengthen our hand in our planned future applications for the ERC / FET programs. Therefore, the project proposal is in full compliance with the TUBITAK-1003 call objectives.

Experimental studies carried out in the project are aimed at developing two different setups. One of these setups involves the development of a nano-scale sensor in accordance with the IEEE 1906.1 Standard definitions, utilizing cantilever sensing of each of the message carrier molecules in the free diffusion environment. In this way, it will be possible to count the message carrier molecules one-by-one using the sensor. The other mechanism involves the detection of nanobeads and electrically charged molecules in microfluidic channels, which are to be microfabricated on a single chip, with Hall and GMR sensors. An experimental platform to be used in the field of molecular communication will be presented in the literature with experimental setups to be developed. We foresee that this platform can be used effectively in different applications.

The data to be obtained by the designed experimental studies will constitute a body of information that the nanonetworking society does not possess. Findings from these experiments will enable our group to develop new theoretical channel models for these transmission environments. The models used so far are not supported by any experimental studies, based on the assumption that macro-scale theories are valid also for the nano-scale. For this reason, the theoretical channel models to be developed in the framework of this project will be enlightening for the nanonetworking society.

Although theoretical channel models will be improved by making use of experimental results, it is difficult to produce theoretical models in complex environments (e.g., structures consisting of bifurcated and/or merged channels). The best tool for such complex structures is still simulation. However, traditional CPU-based simulators are inadequate for the calculation of so many molecules’ mobility. For this reason, a high-performance, GPU-based simulator needs to be developed. To this end, we will develop a GPU-based simulator designed as open source and for general use that will enable the adoption and contribution of the entire nanonetworking society. The inclusion of the nanonetworking society in this process will also contribute to the visibility of our group and Turkish science community.

Modelling Diffusion in Vessel-like Environments for Molecular Communication and Healthcare Applications

With the rapid development of nanotechnology, manufacturing nano-machines with computing capabilities will be feasible in the near future. Such nanomachines by themselves will have limited computing and memory capacity, and will require meticulously planned communication and coordination for performing complex tasks. Therefore, communication systems at those levels are the crucial components to be designed and developed for nanotechnology to achieve its full capacity. Using nano-machines to aid healthcare applications is one of the most substantial and practical area of utilization in nanotechnology. There is also a considerable deficiency in association of theoretical work and useful applications. To this end, it is very important to devise novel, realistic, and in-detail models and simulations which take the biological aspect of such applications into consideration.

Optimization of Communication Parameters in Nanonetworking

The design of nanoscale machines and engineered cells established a new research area, focusing on communication needs of these devices where new types of motivations and constraints apply. For nanomachines, accomplishing complex tasks will only be possible via efficient communication among themselves and external systems. Molecular communication, which is used by many living organisms (e.g., communication via diffusion, ion signaling, microtubule – molecular motors, pheromone signaling), is one of the methods that can be used for inter-nanomachine communication. In our study, the optimum achievable data rate of Communication via Diffusion (CvD), will be explored. Models for co-channel interference and noise will be developed, and their effect on optimum data rate will be investigated.

MoleCom
Molecular Communications in Nano-Communication Networks

The demand for processor power and devices operating at low power has pushed the microchip design to the physical limits of technology. This demand has been the most active driving force for the development of nanotechnology. However, when considered by individually, nano-machines performing significant jobs with limited processing power and memory appear unrealistic without the presence of cooperation by communication. A nano communication network is the technology that will satisfy this demand. Among the nano communication methods, the bio-hybrid approach, which is based on communication with molecules, is the most likely approach to succeed in short term due to the fact that it mimics the naturally existing systems in the nature.

Among the most effective methods that can be used for communication between nano-machines is molecular communication inspired by the communication techniques in biological systems. Although the talents of nano-machines produces with top-down and bottom-up approaches are not satisfactory yet, the biological machines existing in nature can carry on rather complex processes in nano and micrometer scales. Thus, we use the molecular communication approach for nano-networks in this project.

Molecular communication is the general name for the communication systems, where the information exchange is provided via molecules among nano and micro scale devices. In the literature, various methods have been proposed for this new communication system. Communication via Diffusion (CvD) is one of the most important methods among these.

The dynamics of diffusion have to be thoroughly understood, since the messenger molecules sent from one nano-machine to another spread in the medium with diffusion. Moreover, the dynamics of diffusion have to be modeled with nano-communication networks in mind, in order to develop structures consisting of more than one nano-machine and analyze their performance. Such modeling will enable new research mainly on the physical layer. The outcomes of this research will be enlightening for further research on data link layer and transmitter/receiver design.

In this project, our aim is to conduct research on the fields mentioned above in the CvD systems, publish papers that will contribute to the both national and international literature, construct the necessary infrastructure for participating in international projects by increasing the nano-communication networks knowledge base in Turkey, and educate competent PhD-grade researchers.

MC Approaches

Nanotechnology is a new, emerging field dealing with the development and manufacturing of nanoscale materials and machines. These machines, called nanomachines, are expected to have the capabilities of their higher-scale counterparts in the nanoscale. In order to perform more complex tasks, the nanomachines should be able to communicate with each other. Communication systems that enable information exchange between nanomachines are called nanonetworks. The methods proposed to realize nanonetworks are composed of two groups: Traditional Communication Systems and Molecular Communication Systems. Traditional systems are systems already being used by higher scale machines (e.g., electromagnetic communication, cable-based communication, acoustic communication, and heat communication). Molecular communication systems are systems that are either being used by living organism cells or systems inspired from biological cell communication (e.g., communication via diffusion, ion signaling, microtubule - molecular motors, pheromone signaling).
