Scaling laws for molecular communication
In this paper, we investigate information-theoretic scaling laws, independent
from communication strategies, for point-to-point molecular communication,
where it sends/receives information-encoded molecules between nanomachines.
Since the Shannon capacity for this is still an open problem, we first derive
an asymptotic order in a single coordinate, i.e., i) scaling time with constant
number of molecules and ii) scaling molecules with constant time . For a
single coordinate case, we show that the asymptotic scaling is logarithmic in
either coordinate, i.e., and , respectively.
We also study asymptotic behavior of scaling in both time and molecules and
show that, if molecules and time are proportional to each other, then the
asymptotic scaling is linear, i.e., .Comment: Accepted for publication in the 2014 IEEE International Symposium on
