Direction-Aware Greedy Routing Protocol with Recovery Mechanism (DAGR-R) For Flying Ad-Hoc Networks

FANET (Flying Ad Hoc Network) is formed using unmanned aerial vehicles (UAVs) that are used in a variety of areas like emergency communications, surveillance, and monitoring. FANETs communication nodes have a higher level of speed, which results in intermittent connectivity. A swarm of UAVs, commonly referred to as a FANET. Real-time communication between UAVs is required. Drones can maneuver well in three-dimensional spaces, but they have weak batteries that can lead to issues like limited usage time and inefficient routing. Due to the intrinsic network features and environmental factors, routing data in FANETs is challenging, hence a routing mechanism that considers all these factors into account is essential. This paper considers the choosing of the forwarder UAV, and avoiding the looping of messages that impact the performance of a FANET because UAVs have quick movements and frequent topological modifications. For effective communication, this paper proposed a Direction-aware greedy Routing with a Recovery mechanism (DAGR-R). The suggested approach considers the network's ability to adapt on its own in the event of topological changes. The simulation outcome demonstrates that the suggested protocol outperforms other routing protocols in terms of delay, packet delivery, and routing overhead (RO).
