Evolutionary game theoretic resource allocation simulation for molecular
communication

Pages 111-119
Caglar Koca, Meltem Civas, Ozgur B. Akan

Molecular Communication (MC) is an emerging technology using molecules to transfer information
between nanomachines. In this paper, we approach the resource allocation problem in Molecular Nano-
networks (MCN) from the perspective of evolutionary game theory. In particular, we consider an MCN
as an organism having three types of nodes acting as a sensor, relay, and sink, respectively. The
resources are distributed among the nodes according to an evolutionary process, which relies on the
selection of the most successful organisms followed by creating their offspring iteratively. In this regard,
the success of an organism is measured by the total number of dropped messages during its life cycle.
To illustrate the evolution procedure, we design a toy problem, and then solve it analytically and using
the evolution approach for comparison. We further simulate the performance of the evolution approach
on randomly generated organisms. The results reveal the potential of evolutionary game theory tools to
improve the transmission performance of MCNs.

Electric manifestations and social implications of bacteria aggregation from the

Bessel-Keller-Segel equation

Pages 121-128
Huber Nieto-Chaupis

This paper proposes a fair extension of Keller-Segel equation based in the argument that bacteria exhibit
properties electric in their composition. The new mathematical form of this extension involves the
integer-order Bessel functions. With this one can go through the electrodynamics of the representative
scenarios in order to understand the social behavior of bacteria. From the theoretical side this paper
demonstrates that, charged electrically, aggregation of bacteria would give rise to electric currents that
hypothetically are the reasons for social organization and disruption among them. The electrical
properties of bacteria from this mathematical proposal might be relevant in a prospective
implementation of so-called Internet of Bio-Nano Things network, that aims to be characterized for
having a very high signal/noise.
