The class of trees that admit greedy embeddings into the Euclidean plane has been completely characterized, and a greedy embedding of a tree can be found in linear time when it exists. For more general graphs, some greedy embedding algorithms such as the one by Kleinberg start by finding a spanning tree of the given graph, and then construct a greedy embedding of the spanning tree. The result is necessarily also a greedy embedding of the whole graph. However, … WebII. COMPATIBILITY OF GREEDY ROUTINGBASED ROUTING PROTOCOLS Greedy routing is an algorithm that makes the locally opti-mum choice at each stage with the hope of approximating the global optimum. For geographic routing, the greedy routing chooses the lightest weight out-going link at each forwarding node, and the weight of each link is …
