GWPRP: Um Protocolo de Roteamento de Camada Cruzada Guloso e baseado em Localização para Redes Ad-Hoc Voadoras
Abstract
The Flying Ad-hoc Networks (FANETs) enhance the coverage capacity in cellular networks by forwarding data in multiple hops using Unmanned Aerial Vehicles (UAVs). The link quality, however, depends on several features, including the three-dimensional space, not considered by classic routing protocols in ad-hoc networks, even when they take into account node’s location. This paper proposes the GWPRP (Greedy Weighted Perimeter Routing Protocol), a position-based cross-layer greedy routing protocol. GWPRP makes forwarding decisions by considering information about the three-dimensional space, the link layer, and adjacent link stability. The protocol is evaluated in a simulated environment, comparing its performance with GPSR (Greedy Perimeter Stateless Routing) and EE HELLO AODV (Energy Efficient Hello Ad-hoc On-Demand Distance Vector), a variant of AODV for FANETs. The results show that, on average, GWPRP achieves a 2.58% higher packet delivery ratio over AODV and 4.22% over GPSR with lower average end-to-end delay and jitter.
