Analysis of reception process for an absorbing receiver in molecular communication via diffusion

Abstract

Nanotechnology is currently being applied to vast number of elds to overcome the challenges faced with existing technologies that cannot e ciently scale down to nano level. However, considering the limited processing and memory resources of nano-machines, performing complex tasks requires new communication mechanisms. Communication is one of the important issues to be addressed in nano-scale environment. Inspired by the nature, molecular communication via di usion is a candidate to address this issue. Although the reception process of the messenger molecules has a signi cant impact on the performance of molecular communication via di usion, the factors that e ect the received signal for an absorbing receiver have not been investigated in the literature. In this thesis, we rst introduce methods for e cient simulation of molecular communication via di usion to enable further analysis. We propose two novel simulation architectures; a dual-zone simulation model to decrease execution time while preserving simulation accuracy and an HLA based architecture for distributed simulation of molecular communication via di usion. Then, we analyse di erent dimensions of reception process for an absorbing receiver to derive closed form formulations. The results presented enable optimizations that will have a direct e ect on production costs of receptors and the receivers. Finally, we propose a new approach for demodulation of information for an absorbing receiver and analyse energy consumption and data rate for the proposed model.
