  Since the birth of computer and networks, fuelled by pervasive computing and
ubiquitous connectivity, the amount of data stored and transmitted has
exponentially grown through the years. Due to this demand, new solutions for
storing data are needed, and one promising media is the DNA. This storage
solution provides numerous advantages, which includes the ability to store
dense information while achieving long-term stability. However, the question as
how the data can be retrieved from a DNA-based archive, still remains. In this
paper, we aim to address this question by proposing a new storage solution that
relies upon molecular communication, and in particular bacterial nanonetworks.
Our solution allows digitally encoded information to be stored into non-motile
bacteria, which compose an archival architecture of clusters, and to be later
retrieved by engineered motile bacteria, whenever reading operations are
needed. We conducted extensive simulations, in order to determine the
reliability of data retrieval from non-motile storage clusters, placed at
different locations. Aiming to assess the feasibility of our solution, we have
also conducted wet lab experiments that show how bacteria nanonetworks can
effectively retrieve a simple message, such as "Hello World", by conjugation
with non-motile bacteria, and finally mobilize towards a final point.
