A Survey on Position-Based Routing in Mobile Ad-Hoc Networks

by Martin Mauve, Jörg Widmer, Hannes Hartenstein - IEEE Network , 2001
"... We present an overview of ad-hoc routing protocols that make forwarding decisions based on the geographical position of a packet's destination. Other than the destination 's position, each node needs to know only its own position and the position of its one-hop neighbors in order to forwar ..."
