Design of a Communication Module Based on ZigBee Mesh Topology for Unmanned Aerial Vehicles
Abstract
Contemporary Unmanned Aerial Vehicles utilize wireless communication modules based
on WIFI, Bluetooth, cellular networks, LoRa WAN, infrared, WiMAX and a few other flourishing protocols, yet there’s still an ever-growing appetite to remotely control these UAVs
beyond visual line of sight with power efficiency, reliability and most of all scalability. As
the UAV application industry is mature and full of opportunities to explore, the delivery
of such characteristics is expected due to emerging technology enhancements, hence the
design of a unique communication module based on mesh radio for ZigBee.
The latest UAVs take on some sort of wireless protocol as a means of exchanging data
between themselves and ground control stations. The earlier mentioned control schemes
do a great job in addressing remote control beyond visual line of sight and further more
allow for greater data rates and throughput hence transmission of not only telemetry data
but also high resolution videos and images, however; this is mostly in the case of Wi Fi,
WiMAX and use of cellular networks. On the downside, these are usually power intensive
techniques and the greater range that the UAV takes on, transmit and receive power also
keep increasing in that regard for example Wi Fi whose average power is about +10dB or
cellular networks that usually use +4.77dBW for the same. Furthermore, these sometimes
are also not scalable according to application demand not forgetting the continous expenses
involved in setup. In cases where ZigBee has been used to control UAVs, it has been used
either to ensure flight formation without collision or telemetry data collection or otherwise
but all these use a one to one network.
