The Cloud Continuum for Military Deployable Networks: Challenges and Opportunities.

Due to the constant demand for novel network services, including those envisioned by 5G technologies and beyond, the cloud computing paradigm has recently evolved towards distributed systems located preferably at the edge of networks. Fog, edge and even mist computing have emerged in this regard, providing multiple benefits such as low latency or bolstering security. In the specific area of military deployable networks, this so-called cloud continuum has fostered the appearance of multiple use cases, which will be analyzed in detail in this paper, together with their current and future trends in the field. This survey includes works from diverse areas, such as tactical edge, combat cloud or cyber-physical environments, for example. The main objective is to overview the main challenges and opportunities brought by these technologies, as well as future research lines, so that researchers in the field could gather and examine them with a global vision, taking into consideration the specific characteristics of military scenarios.
