Greedy forwarding
A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time.

WebAug 20, 2014 · 3.3 Forwarding packets. The greedy forwarding strategy has two subcomponents: neighbor selection and packet selection. Once a new packet is injected into the VANET, the source node queries the location server for the current location information of the destination node, including its physical position, speed, and the corresponding … There are various approaches, such as single-path, multi-path and flooding-based strategies (see for a survey). Most single-path strategies rely on two techniques: greedy forwarding and face routing. Greedy forwarding tries to bring the message closer to the destination in each step using only local … See more Geographic routing (also called georouting or position-based routing) is a routing principle that relies on geographic position information.
