- Geographic routing (also called georouting or position-based routing) is a routing principle that relies on geographic position information. It is mainly proposed for wireless networks and based on the idea that the source sends a message to the geographic location of the destination instead of using the network address. In the area of packet radio networks, the idea of using position information for routing was first proposed in the 1980s for interconnection networks. Geographic routing requires that each node can determine its own location and that the source is aware of the location of the destination. With this information, a message can be routed to the destination without knowledge of the network topology or a prior route discovery. (en)

- Greedy forwarding variants: The source node has different choices to find a relay node for further forwarding a message to the destination . A = Nearest with Forwarding Progress , B = Most Forwarding progress within Radius , C = Compass Routing, E = Greedy (en)
- Face routing: A message is routed along the interior of the faces of the communication graph, with face changes at the edges crossing the S-D-line . The final routing path is shown in blue. (en)
