“…In addition, UAVs and UAV-assisted wireless networks have already been proven to be invaluable in civil applications, such as monitoring fires, transporting goods, detecting oil leakages, and providing network services [ 2 ]. UAVs may be employed as mobile base stations (BSs) or relays as they can be deployed for flexible coverage areas on demand, especially for future sixth-generation (6G) wireless networks [ 3 ]. UAV-BSs can enable the existing wireless communication networks to increase another dimension such that future wireless networks can be three-dimensional in space [ 4 , 5 , 6 ], particularly in situations where it is difficult or impossible to connect nodes using the conventional terrestrially based network infrastructure.…”

Unmanned aerial vehicles (UAVs) employed as airborne base stations (BSs) are considered the essential components in future sixth-generation wireless networks due to their mobility and line-of-sight communication links. For a UAV-assisted ad hoc network, its total channel capacity is greatly influenced by the deployment of UAV-BSs and the corresponding coverage layouts, where square and hexagonal cells are partitioned to divide the zones individual UAVs should serve. In this paper, the total channel capacities of these two kinds of coverage layouts are evaluated using our proposed novel computationally efficient channel capacity estimation scheme. The mean distance (MD) between a UAV-BS in the network and its served users as well as the MD from these users to the neighboring UAV-BSs are incorporated into the estimation of the achievable total channel capacity. We can significantly reduce the computational complexity by using a new polygon division strategy. The simulation results demonstrate that the square cell coverage layout can always lead to a superior channel capacity (with an average increase of 7.67% to be precise) to the hexagonal cell coverage layout for UAV-assisted ad hoc networks.
