WebApr 22, 2024 · Greedy routing algorithms are easy to understand and easy to implement. These algorithms are highly efficient for the route discovery process. A general structure of the greedy forwarding approach is shown in Fig. 1 where S and D are source and destination nodes respectively, and other nodes may be used as intermediate nodes. WebAbstract. Greedy routing computes paths between nodes in a network by successively moving to the neighbor closest to the target with respect to coordinates given by an embedding into some metric space. Its advantage is that only local information is used for routing decisions. We present different algorithms for generating graph embeddings …
