  Molecular communication is a new, active area of research that has created a
paradigm shift in the way a communication system is perceived. An artificial
molecular communication network is created using biological molecules for
encoding, transmitting and decoding the symbols to convey information. In
addition to typical biological molecules, we are also exploring other classes
of molecules that possess unique distinctive features which can be potentially
exploited for establishing reliable communications. Odor molecules are one such
class of molecules which possess several distinctive features such as
Intensity, Headonic tone which provides a basis to convey the information in an
olfactory communication system. In our work, we investigate the ICT
(information and communication theory) perspective of the olfactory
communications by evaluating the channel capacity of an odor molecular
communication (OMC) system with the help of a novel modulation scheme viz. odor
intensity shift keying (OISK), where information is being conveyed from the
intensity level of an odor. Furthermore, we also analyse the effects of
critical parameters like temperature and noise on the achievable channel
capacity to provide an insight about the resilience of the proposed OMC system
towards any such anomaly faced by it.
