Abstract
Unmanned Aerial Vehicles (UAVs) or drones have become extremely popular and are used in various
commercial applications. When multiple UAVs communicate and work together, they form a UAV network.
A private UAV network or Local Area Network of Drones (LoDs) is a special type of UAV network which
has the minimum number of UAVs to carry out a certain task. All UAVs in a LoD use the wireless medium
to send and receive the data as well as the control signals. An organization or a single owner will be more
interested in this type of network, where they want multiple UAVs to scan an area, communicate with each
other, and send all the images and live video streams to a single ground station. The currently available
commercial UAVs Can send the video signals to and receive control signals only from their own ground
station controllers. However, in an LoD network where UAVs are connected in tandem, the UAVs that are
in the middle of the network have to carry the control and video signals of other UAVs. Given the limited
processing power and dynamic memory capacity of UAVs, this would increase the queuing delays and
performance.
In this paper, we study the frame formats of existing control, feedback, and data messages of commercial
AR UAVs and propose a new approach to construct the payloads of control and feedback frames that are
suitable for an LoDs. We compare the performance of our approach of single control and feedback frame
for all UAVs in a LoD branch with that of separate control and feedback frames for each UAV. We
calculate and compare the UAV node processing delay in both types of signaling mechanisms and show
that the single control and feedback frame signaling has less delay on the average.
