**1.1 Motivation**

CA support to various ground domains or terrestrial networks has lately been identified as a critical success factor for a large number of jobs that require significant enhancement of timeframe, connectivity, and flexibility. As a result, a really well notion of this paradigm must be precisely specified while taking into account the various CA criteria. This enables CAs to better support ground-users (GUs) and complete their assigned tasks. CAs can overcome communication gaps in ground networks and monitor hostile settings or disaster zones [3]. Aside from the traditional CA difficulties, a number of new ones, including such technical and standardisation considerations, societal privacy and safety, and mobility optimization, require further attention. The possible benefits of CAs raise the following concerns:


• How can CAs improve ground network performance as well as better serve GUs?

Inspired from the afforested questions, we present a full overview of CA's extant achievements and control mechanisms in this chapter.
