Influence of Sub-Processes Timescale Differences on Molecular Communication Systems Performance

摘要

Molecular communication (MC) processes consist of sub-processes that are physical, biological or biophysical in nature. Unlike the classical electromagnetic communication systems, each constituent sub-process may operate on a different timescale. Existing bio-MC models do not take the influence of the differences in the sub-processes timescales into consideration. Hence, information provided by the multiple timescale characteristics of the bio-MC process is not readily available. In this paper, we explore the effect of variation in the timescales of some distinct sub-processes that make up the whole diffusion- based bio-MC process on system performance. To do that, we present an event-driven stochastic model for the bio-MC systems that takes the timescale variance into consideration. Using this model, we explore the impact of the sub-processes timescale variations on the performance of a typical bio-MC system. Relationships between the timescale factors and conventional electromagnetic parameters such as antenna gain are highlighted.
