Abstract

Routing protocols enable reliable communication in Unmanned Aerial Vehicle (UAV) networks, particularly Flying Ad-hoc Networks (FANETs), amid high-speed 3D mobility, dynamic topologies, and energy limits. Key challenges include intermittent links due to mobility, limited energy resources, variable network density, and the need to minimize end-to-end delay while maximizing throughput and fault tolerance. This paper classifies recent UAV routing protocols into topology-based routing protocols, position-based routing protocols, and hierarchical-based routing protocols. It reviews mechanisms, including predictive clustering and energy-aware metrics, addresses challenges like link failures and scalability, and compares performances via simulations, showing the superiority of hybrids in terms of throughput and packet delivery.

Keywords: UAV; FANETs; Routing Protocol; Topology Based Routing protocols; Position Based Routing Protocols; Hierarchical Based Routing Protocols
