SUMMARY:

The scanning area procedure of the probable impact region is a mandatory step in the pre-launch 

phase of any rocket. The objective is restrict the presence of unauthorized vessels, avoiding 

possible accidents and, consequently, preserv human lives. Considering the high operational cost 

of this procedure, normally performed by a P-95 aircraft, the SpaceVANT II project proposed the 

execution of the area scan by a fleet of Unmanned Aerial Vehicles (UAVs) that, acting in a 

cooperative way, have the ability to execute the mission with lower cost and operational complexity. 

In this context, it is essential to create a communication network able to ensure the exchange of 

information between the aircraft that make up the system. One of the most used alternatives to 

provide this communication network is mobile ad hoc network (MANET) protocols adapted for 

flying ad hoc networks (FANET). However, managing the dynamic behavior of this type of network 

in order to minimize disconnections and enable the necessary conditions for the operation of 

applications on board aircraft is not simple and has found limitations in the solutions adopted. In 

this perspective, this thesis proposed a management based Software Defined Networking (SDN) 

called SD-FANET. Design on a distributed and hierarchical architecture, the SD-FANET control 

plane allows centralized management and assigns the controller the ability to program the 

switches, changing the data forwarding from a holistic view of the network. The SDN approach 

allows the use of different path selection algorithms, which adds more flexibility and improvement 

to the forwarding process. To validate the proposed solution, experiments were carried out in the 

emulated environment provided by Mininet-Wifi and a proof of concept based on a prototype using 

a communication protocol developed to enable transmission of images in ZigBee communication 

links embedded in DJI Phantom 3 Standard drones. The results showed that the throughput 

obtained by SD-FANET was 22.2% better than MANET protocols and 5.4% in relation to the local 

SDN controller. The average recovery time provides by resilience mechanisms was about 1.5 s.
