Similar to technologies that initially started at a military base, unmanned aerial vehicles (UAVs) will soon be affecting civilian life. To date, several industries have built and commercially supplies low-end UAVs technologies for various non-military purposes. However, most of these UAVs are recreational and remote-controlled toys that only fly in secluded areas with minimum impact on the airspace. However, the rate at which technology is advancing, civilian UAVs are no longer restricted to creational use. Despite advancements, the existing collision avoidance systems that are currently regulated within the civilian airspace were unable to integrate both manned and unmanned aircraft. The research discussed in this post therefore presents the design, implementation, and verification of two types of cooperative collision avoidance algorithms for UAVs in multi-aircraft conflict scenarios.
