The concept of communication via breath is introduced under the molecular com
munication system, where data can be exchanged through inhalation and exhalation.
Those data are carried by volatile organic compounds (VOCs) or pathogens and
transferred through an aerosol channel. In this thesis, we propose a molecular com
munication model for an instantaneous source in a bounded indoor environment. The
walls of this environment could be reﬂectors and/or absorbers by adjusting the value
of deposition velocity. We assume a puﬀ source in a given location and study the per
formance of a point source since it is the basic element that can be used to derive the
concentration of breath, cough, and sneezing, where the concentration of continuous
source can be found by integrating a point source over space and time domains. Also,
we show some numerical results to visualize the performance of these mathematical
models and evaluate them.
As a case study, we consider a real-life scenario of detecting a virus from an
exhaled breath of a person standing in an indoor bounded room with reﬂective and
absorptive walls. We derive the spatial-temporal concentration of an exhaled virus at
the molecules source and the receiver in the room. Finally, we study the probability
of misdetection using a suitable bio-sensor.
