Greedy Distance Vector Routing

Greedy Distance Vector (GDV) is the first geographic routing protocol designed to optimize end-to-end path costs using any additive routing metric, such as: hop count, latency, ETX, ETT, etc. GDV requires no node location information. Instead, GDV uses estimated routing costs to destinations which are locally computed from node positions in a virtual space. GDV makes use of VPoD, a new virtual positioning protocol for wireless networks. Prior virtual positioning systems (e.g., Vivaldi and GNP) were designed for Internet hosts and require that each host measures latencies (routing costs) to distant hosts or landmarks. VPoD does not have this requirement and uses only routing costs between directly connected nodes.
