Wireless communication for bio-chemical nanosensor

Short project description

In this project, wireless communication for biochemical nanosensor will be explored by means of simulation. Nanotechnology enables the creation of nanoscale components, which are able to perform simple specific tasks like computing, data storing, sensing and actuation. Based on these components very small devices - so-called nano-devices - can be constructed and used to build small nano sensor networks with applications in bio-medicine and eHealth. Communication among the devices will be wireless. Due to the small size of these devices the carrier frequency has to be at several THz. Before such a nano network can be realized a couple of basic problems have to be solved such as the characterization of the THz propagation channel in nano scales, the exploration of the appropriate (novel) physical layer techniques such as modulation and coding as well as the development of novel protocol methods taking into account the specific interference and multiple access situation. On the other hand the feasibility to design and fabricate the required nanoscale transceivers and antennas has to be investigated. All these aspects will be dealt with in this project in the context of applying the nano sensor network approach to the area of bio-medicine.

The research in this project will be based on two pillars. The group of Prof. Kürner at TU Braunschweig has a strong background and long-lasting experience in radio channel characterization, the development of THz communication systems and developing simulation tools. This will form one pillar. The second pillar will be the technology developed in LENA, which will be the basis for investigating the possibilities to build transceivers and antennas. Nano communications is in a very early stage, which does not allow to do most of the investigation experimentally. Therefore the focus of this project will be on theoretical investigations and simulations. Hence, the main goal of the project is to provide the basic building blocks for the development of a simulation environment for nanoscale communication in biomedical applications. These building blocks are channel and propagation models, transceiver and antenna models as well as modules to enable link-level and system-level simulations required to develop the solutions for the physical layer techniques and protocol.
