Each UAV hosts a TIEN device which can broadcast and receive the relevant traffic information and create a local traffic view
The ground systems receive information from different UAVs and relay them to other UAVs and data centers.
Data center combines the information from different ground systems into an overarching global traffic view of UAVs in the city
The information exchange system is affordable for various users with minimal capital costs.
Robust against cyber-attacks that have low technology requirements.
Provide on-time information for detect-and-avoid system to ensure vehicle clearances.
Suitable for operations in urban environments amidst skyscrapers with UAVs outside line of sight
Operates with ad-hoc networks enabling seamless communication connectivity
The flexible framework allows integration of customized data from the operator into the communication network.
Significant Improvement over ADS-B, a mandatory equipment for commercial aviation
Preliminary simulations show a clear improvement over single state broadcasts from traditional ADS-B like distributed surveillance systems. The results show that the system can have longer effective broadcasting range than the actual broadcasting range. And, the results show the effective broadcasting range increases with maximum blockchain length. This characteristic is useful in both metropolitan and rural areas. In rural areas, UAV operators can monitor operations of their UAVs by, beside the working UAVs, deploying several relay UAVs to help transmit traffic data to operators. In metropolitan areas, both onboard and ground systems can have shorter broadcasting ranges to reduce power consumptions without impacts its performance.
