Geographic routing in ad hoc and sensor networks prevails recent years for its efficiency and scalability. The Combined Greedy-Face routing (CGF) is a major family of geographic routing that equipped greedy forwarding scheme with a face routing scheme as a backup scheme to resumes forwarding traffic when greedy forwarding fails. Although the backup scheme enable the routing a deliver guaranteed

In this paper, we propose a novel geographic routing approach called reactive geographic forwarding (RGF). RGF reactively discovers the relay nodes and constructs paths to destination through the relay node. Simulation results on various network topologies show that RGF significantly improves the performance of geographic routing.
