ground; these UAVs facilitate the mission by conveying the scene accurately
to the decision maker. In light of the
technological progress of the armed
forces, UAVs have become active
weapons that support the front lines in
battle by tracking the movement of the
enemy on the battlefield.
Since more battles occur in constrained areas where it is difficult to
transmit information over fixed networks, using UAVs' ad-hoc networking
communication architecture in these
areas is a challenge. There are several
ways to integrate communication architecture to connect multiple UAVs in a
mesh network, but network latency affects the quality of battlefield information transfer via the UAV. The same is
true for situational awareness views at
the operations centers; network latency
has a negative impact on decision makers in the theatre of operations.
In constrained areas, operators use
UAVs to support mission achievement
through reconnaissance to detect the
enemy's position in battle. Therefore, a
delay in signal communication between
UAVs and the ground station will impact ground forces' movement; commanders will not have enough information about the situation on the ground
to guide or inform ground forces to attack or defend, which can cause loss of
position, as well as increase the possibility of causalities.
The military needs an adaptive flexible network architecture to reduce vulnerability arising from latency. Future
wars will require ensuring performance
of packets in the network and providing
a real-time picture to avoid lack of communication in battlefield environments.
Therefore, network topology, network
architecture, wireless propagation, network routing, network performance,
and network applications are all needed
to face this phenomenon. These technologies facilitate the exchange of information among nodes and also defend
network capabilities in the operational
theater for continued transmission.
Although some research has been conducted in the area of reinforcing signal
strength between UAVs to ensure that
network performance endures, the question remains of what type of network ar-

chitecture maximizes signal performance
in the face of constraints. This requires a
network technology capable of facilitating electronic integration among various
systems to establish efficient coordination. Given these requirements, improving network technology through effec-

tive systems architecture can ensure
communication between a ground station and multiple UAVs' nodes to reinforce network and telecommunication
technology in mesh networks.
This research focuses on the effect of
the UAV nodes' altitude from a ground
