Review on Efficient Requirements of Greedy, Face, and Combined Greedy-Face Routing
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. This paper gives the brief introduction about the three geographic routing. Namely Greedy routing, Face routing and combined greedy face routing. In this geographic routing intermediate nodes maintain a key role.
