Bacteria-based communication in nanonetworks

This paper describes a Bacteria-based Nanonetwork for communication between eukaryotic cell sized nano devices. The communication is achieved by the exchange of DNA molecules which are transported by bacteria guided by chemotaxis. First, the modules of the network are described and all the biological phenomena that support the basic communication steps are explained in detail. Then an analytical model is developed to assess the communication range and the network performance in terms of capacity and end-to-end delay by considering the available information about the biological mechanisms used. As there are no appropriate estimates of the propagation delay introduced by bacterial chemotaxis, our newly developed simulator is introduced which helps us to obtain the statistics on bacteria propagation. Finally, by combining the analytical model with the simulation results, a network performance in terms of end-to-end delay, capacity and end-to-end throughput is obtained which is 4 orders of magnitude higher than the other molecular communication approaches.
