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, … WebFeb 9, 2024 · For Congestion detection, we propose a use of a location-based algorithm called GPSR [9, 10]—greedy perimeter stateless routing. GPSR combines greedy forwarding and perimeter forwarding for routing the destination. The main aim of GPSR is to increase the mobility rate under increasing number of nodes in a network.
