Vücut-içi moleküler haberleşme: Çoklu-erişimli sinaptik kanal üzerine teorik bir çalışma

Molecular communication is a novel nanoscale communication paradigm, in which information is encoded in messenger molecules for transmission and reception. Indeed, human body is a large-scale heterogeneous communication network of nanonetworks composed of interacting nanomachines, i.e., cells, whose functionalities primarily depend on nanoscale molecular communications. In this thesis, we introduce the elementary models for significant intra-body molecular communication channels, and then, discuss molecular nanonetworks belonging to multi-terminal extensions of channel models. Our objective is to learn from the elegant molecular communication mechanisms inside us for engineering practical communication techniques for emerging nanonetworks. Besides, we aim to pave the way for the advancement of revolutionary diagnosis and treatment techniques inspired from information and communication technologies, which is promising for future nanomedicine and bio-inspired molecular communication applications. Furthermore, we model the multiple-access synaptic communication channel, and analyze the synaptic transmission performance by incorporating the role of presynaptic input correlation. Using this model, we concentrate on the disorders characterized by abnormalities in the synaptic terminals and connections, and establish relations between neural diseases and synaptic communication problems. Additionally, we investigate the multiuser interference in synaptic communication channel and provide a performance analysis for the postsynaptic rate. Moreover, we investigate the performance, i.e., rate and delay, tradeoffs in messenger based molecular nanonetworks, and analyze a molecular network coding scheme to investigate the communication rate improvement.
