Geographic Routing Using Hyperbolic Space - cs.cornell.edu

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 … 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.
